Aerial reconnaissance is reconnaissance for a military or strategic purpose that is conducted using reconnaissance aircraft. The role of reconnaissance can fulfil a variety of requirements including artillery spotting, the collection of imagery intelligence, and the observation of enemy maneuvers.

History

Early developments

After the French Revolution, the new rulers became interested in using the balloon to observe enemy manoeuvres and appointed scientist Charles Coutelle to conduct studies using the balloon L'Entreprenant, the first military reconnaissance aircraft. The balloon found its first use in the 1794 conflict with Austria, where in the Battle of Fleurus they gathered information. Moreover, the presence of the balloon had a demoralizing effect on the Austrian troops, which improved the likelihood of victory for the French troops. To operate such balloons, a new unit of the French military, the French Aerostatic Corps, was established; this organisation has been recognised as being the world's first air force.

After the invention of photography, primitive aerial photographs were made of the ground from manned and unmanned balloons, starting in the 1860s, and from tethered kites from the 1880s onwards. An example was Arthur Batut's kite-borne camera photographs of Labruguière starting from 1889.

In the early 20th century, Julius Neubronner experimented with pigeon photography. These pigeons carried small cameras that incorporated timers.

Ludwig Rahrmann in 1891 patented a means of attaching a camera to a large calibre artillery projectile or rocket, and this inspired Alfred Maul to develop his Maul Camera Rockets starting in 1903. Alfred Nobel in 1896 had already built the first rocket carrying a camera, which took photographs of the Swedish landscape during its flights. Maul improved his camera rockets and the Austrian Army even tested them in the Turkish-Bulgarian War in 1912 and 1913, but by then and from that time on camera-carrying aircraft were found to be superior.

The first use of airplanes in combat missions was by the Italian Air Force during the Italo-Turkish War of 1911–1912. On 23 October 1911, an Italian pilot, Capt. Carlo Piazza, flew over the Turkish lines in Libya to conduct an aerial reconnaissance mission; Another aviation first occurred on November 1 with the first ever dropping of an aerial bomb, performed by Sottotenente Giulio Gavotti, on Turkish troops from an early model of Etrich Taube aircraft.

The first reconnaissance flight in Europe took place in Greece, over Thessaly, on 18 October 1912 (5 October by the Julian calendar) over the Ottoman army. The pilot also dropped some hand-grenades over the Turkish Army barracks, although without success. This was the first day of the Balkan wars, and during the same day a similar mission was flown by German mercenaries in Ottoman service in the Thrace front against the Bulgarians. The Greek and the Ottoman mission flown during the same day are the first military aviation combat missions in a conventional war. A few days later, on 16 October 1912, a Bulgarian Albatros aircraft performed one of Europe's first reconnaissance flight in combat conditions, against the Turkish lines on the Balkan peninsula, during the Balkan Wars of 1912–1913.

Maturation during the First World War

The use of aerial photography rapidly matured during the First World War, as aircraft used for reconnaissance purposes were outfitted with cameras to record enemy movements and defences. At the start of the conflict, the usefulness of aerial photography was not fully appreciated, with reconnaissance being accomplished with map sketching from the air.

Frederick Charles Victor Laws started experiments in aerial photography in 1912 with No. 1 Squadron RAF using the British dirigible Beta. He discovered that vertical photos taken with 60% overlap could be used to create a stereoscopic effect when viewed in a stereoscope, thus creating a perception of depth that could aid in cartography and in intelligence derived from aerial images. The dirigibles were eventually allocated to the Royal Navy, so Laws formed the first aerial reconnaissance unit of fixed-wing aircraft; this became No. 3 Squadron RAF.

Germany was one of the first countries to adopt the use of a camera for aerial reconnaissance, opting for a Görz, in 1913. French Military Aviation began the war with several squadrons of Bleriot observation planes, equipped with cameras for reconnaissance. The French Army developed procedures for getting prints into the hands of field commanders in record time.

The Royal Flying Corps recon pilots began to use cameras for recording their observations in 1914 and by the Battle of Neuve Chapelle in 1915 the entire system of German trenches was being photographed. The first purpose-built and practical aerial camera was invented by Captain John Moore-Brabazon in 1915 with the help of the Thornton-Pickard company, greatly enhancing the efficiency of aerial photography. The camera was inserted into the floor of the aircraft and could be triggered by the pilot at intervals.

Moore-Brabazon also pioneered the incorporation of stereoscopic techniques into aerial photography, allowing the height of objects on the landscape to be discerned by comparing photographs taken at different angles. In 1916, the Austro-Hungarian Empire made vertical camera axis aerial photos above Italy for map-making.

By the end of the war, aerial cameras had dramatically increased in size and focal power and were used increasingly frequently as they proved their pivotal military worth; by 1918 both sides were photographing the entire front twice a day and had taken over half a million photos since the beginning of the conflict.

In January 1918, General Allenby used five Australian pilots from No. 1 Squadron AFC to photograph a 624 square miles (1,620 km2) area in Palestine as an aid to correcting and improving maps of the Turkish front. This was a pioneering use of aerial photography as an aid for cartography. Lieutenants Leonard Taplin, Allan Runciman Brown, H. L. Fraser, Edward Patrick Kenny, and L. W. Rogers photographed a block of land stretching from the Turkish front lines 32 miles (51 km) deep into their rear areas. Beginning 5 January, they flew with a fighter escort to ward off enemy fighters. Using Royal Aircraft Factory BE.12 and Martinsyde airplanes, they not only overcame enemy air attacks, but also bucked 65 mile-per-hour winds, anti-aircraft fire, and malfunctioning equipment to complete their task circa 19 January 1918.

Second World War

High-speed reconnaissance aircraft

Sidney Cotton's Lockheed 12A, in which he made a high-speed reconnaissance flight in 1940.

During 1928, the Royal Air Force (RAF) developed an electric heating system for the aerial camera; this innovation allowed reconnaissance aircraft to take pictures from very high altitudes without the camera parts freezing. In 1939, Sidney Cotton and Flying Officer Maurice Longbottom of the RAF suggested that airborne reconnaissance may be a task better suited to fast, small aircraft which would use their speed and high service ceiling to avoid detection and interception. Although this may perhaps seem obvious today with modern reconnaissance tasks performed by fast, high flying aircraft, at the time it was radical thinking.

This PRU Blue Spitfire PR Mk XI (PL965) was a long range, high-altitude reconnaissance variant capable of flying from airfields in England and photographing targets in Berlin.

Cotton and Longbottom proposed the use of Spitfires with their armament and radios removed and replaced with extra fuel and cameras. This concept led to the development of the Spitfire PR variants. With their armaments removed, these planes could attain a maximum speed of 396 mph while flying at an altitude of 30,000 feet, and were used for photo-reconnaissance missions. The Spitfire PR was fitted with five cameras, which were heated to ensure good results (while the cockpit was not). In the reconnaissance role, the Spitfire proved to be extremely successful, resulting in numerous Spitfire variants being built specifically for that purpose. These served initially with what later became No. 1 Photographic Reconnaissance Unit (PRU).

Other fighters were also adapted for photo-reconnaissance, including the British Mosquito and the American P-38 Lightning and P-51 Mustang. Such aircraft were painted in PRU Blue or Pink camouflage colours to make them difficult to spot in the air, and often were stripped of weapons or had engines modified for better performance at high altitudes (over 40,000 feet).

The American F-4, a factory modification of the Lockheed P-38 Lightning, replaced the nose-mounted four machine guns and cannon with four high-quality K-17 cameras. Approximately 120 F-4 and F-4As were hurriedly made available by March 1942, reaching the 8th Photographic Squadron in Australia by April (the first P-38s to see action). The F-4 had an early advantage of long range and high speed combined with ability to fly at high altitude; a potent combination for reconnaissance. In the last half of 1942 Lockheed would produce 96 F-5As, based on the P-38G with all later P-38 photo-reconnaissance variants designated F-5. In its reconnaissance role, the Lightning was so effective that over 1,200 F-4 and F-5 variants were delivered by Lockheed, and it was the United States Army Air Forces's (USAAF) primary photo-reconnaissance type used throughout the war in all combat theatres. The Mustang F-6 arrived later in the conflict and, by spring 1945, became the dominant reconnaissance type flown by the USAAF in the European theatre. American photo-reconnaissance operations in Europe were centred at RAF Mount Farm, with the resulting photographs transferred to Medmenham for interpretation. Approximately 15,000 Fairchild K-20 aerial cameras were manufactured for use in Allied reconnaissance aircraft between 1941 and 1945.

The British de Havilland Mosquito excelled in the photo-reconnaissance role; the converted bomber was fitted with three cameras installed in what had been the bomb bay. It had a cruising speed of 255 mph, maximum speed of 362 mph and a maximum altitude of 35,000 feet. The first converted PRU (Photo-Reconnaissance Unit) Mosquito was delivered to RAF Benson in July 1941 by Geoffrey de Havilland himself. The PR Mk XVI and later variants had pressurized cockpits and also pressurized central and inner wing tanks to reduce fuel vaporization at high altitude. The Mosquito was faster than most enemy fighters at 35,000 ft, and could roam almost anywhere. Colonel Roy M. Stanley II of United States Air Force (USAF) stated of the aircraft: "I consider the Mosquito the best photo-reconnaissance aircraft of the war". The United States Army Air Forces (USAAF) designation for the photo-reconnaissance Mosquito was F-8.

Apart from (for example) the Mosquito, most World War II bombers were not as fast as fighters, although they were effective for aerial reconnaissance due to their long range, inherent stability in flight and capacity to carry large camera payloads. American bombers with top speeds of less than 300 mph used for reconnaissance include the B-24 Liberator (photo-reconnaissance variant designated F-7), B-25 Mitchell (F-10) and B-17 Flying Fortress (F-9). The revolutionary B-29 Superfortress was the world's largest combat-operational bomber when it appeared in 1944, with a top speed of over 350 mph which at that time was outstanding for such a large and heavy aircraft; the B-29 also had a pressurized cabin for high altitude flight. The photographic reconnaissance version of the B-29 was designated F-13 and carried a camera suite of three K-17B, two K-22 and one K-18 with provisions for others; it also retained the standard B-29 defensive armament of a dozen .50 caliber machine guns. In November 1944 an F-13 conducted the first flight by an Allied aircraft over Tokyo since the Doolittle Raid of April 1942. The Consolidated B-32 Dominator was also used for reconnaissance over Japan in August 1945.

The Japanese Army Mitsubishi Ki-46, a twin-engined aircraft designed expressly for the reconnaissance role with defensive armament of 1 light machine gun, entered service in 1941. Codenamed "Dinah" this aircraft was fast, elusive and proved difficult for Allied fighters to destroy. More than 1,500 Ki-46s were built and its performance was upgraded later in the war with the Ki-46-III variant. Another purpose-designed reconnaissance aircraft for the Imperial Japanese Navy Air Service was the carrier-based, single-engine Nakajima C6N Saiun ("Iridescent Cloud"). Codenamed "Myrt" by the Allies, the Nakajima C6N first flew in 1943 and was also highly elusive to American aircraft due to its excellent performance and speed of almost 400 mph. As fate would have it on 15 August 1945, a C6N1 was the last aircraft to be shot down in World War II. Japan also developed the high-altitude Tachikawa Ki-74 reconnaissance bomber, which was in a similar class of performance as the Mosquito, but only 16 were built and did not see operational service.

The Luftwaffe began deploying jet aircraft in combat in 1944, and the twin-jet Arado Ar 234 Blitz ("Lightning") reconnaissance bomber was the world's first operational jet-powered bomber. The Ar 234B-1 was equipped with two Rb 50/30 or Rb 75/30 cameras, and its top speed of 460 mph allowed it to outrun the fastest non-jet Allied fighters of the time. The twin piston-engined Junkers Ju 388 high-altitude bomber was an ultimate evolution of the Ju 88 by way of the Ju 188. The photographic reconnaissance Ju 388L variant had a pressurized cockpit from the Ju 388's original multi-role conception as not only a bomber but also a night fighter and bomber destroyer, due to RLM's perceived threat of the U.S.'s high-altitude B-29 (which ended up not being deployed in Europe). Approximately 50 Ju 388Ls were produced under rapidly deteriorating conditions at the end of the war. As with other high performance weapons introduced by Nazi Germany, too many circumstances in the war's logistics had changed by late 1944 for such aircraft to have any impact.

The DFS 228 was a rocket-powered high-altitude reconnaissance aircraft under development in the latter part of World War II. It was designed by Felix Kracht at the Deutsche Forschungsanstalt für Segelflug (German Institute for Sailplane Flight) and in concept is an interesting precursor to the post-war American U-2, being essentially a powered long-wingspan glider intended solely for the high-altitude aerial reconnaissance role. Advanced features of the DFS 228 design included a pressurized escape capsule for the pilot. The aircraft never flew under rocket power with only unpowered glider prototypes flown prior to May 1945.

Imagery analysis

RAF Medmenham, where aerial reconnaissance intelligence was analysed.

The collection and interpretation of aerial reconnaissance intelligence became a considerable enterprise during the war. Beginning in 1941, RAF Medmenham was the main interpretation centre for photographic reconnaissance operations in the European and Mediterranean theatres. The Central Interpretation Unit (CIU) was later amalgamated with the Bomber Command Damage Assessment Section and the Night Photographic Interpretation Section of No 3 Photographic Reconnaissance Unit, RAF Oakington, in 1942.

During 1942 and 1943, the CIU gradually expanded and was involved in the planning stages of practically every operation of the war, and in every aspect of intelligence. In 1945, daily intake of material averaged 25,000 negatives and 60,000 prints. Thirty-six million prints were made during the war. By VE-day, the print library, which documented and stored worldwide cover, held 5,000,000 prints from which 40,000 reports had been produced.

American personnel had for some time formed an increasing part of the CIU and on 1 May 1944 this was finally recognised by changing the title of the unit to the Allied Central Interpretation Unit (ACIU). There were then over 1,700 personnel on the unit's strength. A large number of photographic interpreters were recruited from the Hollywood Film Studios including Xavier Atencio. Two renowned archaeologists also worked there as interpreters: Dorothy Garrod, the first woman to hold an Oxbridge Chair, and Glyn Daniel, who went on to gain popular acclaim as the host of the television game show Animal, Vegetable or Mineral?.

Sidney Cotton's aerial photographs were far ahead of their time. Together with other members of his reconnaissance squadron, he pioneered the technique of high-altitude, high-speed photography that was instrumental in revealing the locations of many crucial military and intelligence targets. Cotton also worked on ideas such as a prototype specialist reconnaissance aircraft and further refinements of photographic equipment. At its peak, British reconnaissance flights yielded 50,000 images per day to interpret.

Of particular significance in the success of the work of Medmenham was the use of stereoscopic images, using a between plate overlap of exactly 60%. Despite initial scepticism about the possibility of German rocket development, stereoscopic analysis proved its existence and major operations, including the 1943 offensives against the V-2 rocket development plant at Peenemünde, were made possible by work carried out at Medmenham. Later offensives were also made against potential launch sites at Wizernes and 96 other launch sites in northern France.

Particularly important sites were measured, from the images, using Swiss stereoautograph machines made by Wild (Heerbrugg) and physical models made to facilitate understanding of what was there or what it was for.

It is claimed that Medmanham's greatest operational success was Operation Crossbow which, from 23 December 1943, destroyed the V-1 infrastructure in northern France. According to R.V. Jones, photographs were used to establish the size and the characteristic launching mechanisms for both the V-1 flying bomb and the V-2 rocket.

Cold War

Immediately after the Second World War, the long range aerial reconnaissance role was quickly taken up by adapted jet bombers, such as the English Electric Canberra and its American development the Martin B-57, that were capable of flying higher or faster than enemy aircraft or defenses. Shortly after the Korean War, the United States begun to use RB-47 aircraft; these were at first were converted B-47 bombers, but later purposely built as RB-47 reconnaissance aircraft that had no bombing capability. Large cameras were mounted in the plane's belly and a truncated bomb bay was used for carrying photoflash bombs. Later versions of the RB-47, such as the RB-47H, were extensively modified for signals intelligence (ELINT), with additional equipment operator crew stations in the bomb bay; unarmed weather reconnaissance WB-47s with cameras and meteorological instruments also served the United States Air Force (USAF) during the 1960s.

The onset of the Cold War led to development of several highly specialized and clandestine strategic reconnaissance aircraft, or spy planes, such as the Lockheed U-2 and its successor the SR-71 Blackbird (both from the United States). Flying these aircraft became an exceptionally demanding task, with crews specially selected and trained due to the aircraft's extreme performance characteristics in addition to risk of being captured as spies. The American U-2 shot down in Soviet airspace and capture of its pilot caused political turmoil at the height of the Cold War.

Beginning in the early 1960s, United States aerial and satellite reconnaissance was coordinated by the National Reconnaissance Office (NRO). Risks such as loss or capture of reconnaissance aircraft crewmembers also contributed to U.S. development of the Ryan Model 147 RPV (Remotely Piloted Vehicle) unmanned drone aircraft which were partly funded by the NRO during the 1960s.

During the 1960s, the United States Navy opted to convert many of its supersonic carrier-based nuclear bomber, the North American A-5 Vigilante, into the capable RA-5C Vigilante reconnaissance aircraft. Beginning in the early 1980s, the U.S. Navy outfitted and deployed Grumman F-14 Tomcat aircraft in one squadron aboard an aircraft carrier with a system called Tactical Airborne Reconnaissance Pod System (TARPS), which provided naval aerial reconnaissance capability until the Tomcat's retirement in 2006.

Post Cold War

Since the 1980s, there has been an increasing tendency for militaries to rely upon assets other than manned aircraft to perform aerial reconnaissance. Alternative platforms include the use of surveillance satellites and unmanned aerial vehicles (UAVs), such as the armed MQ-9 Reaper. By 2005, such UAVs could reportedly be equipped with compact cameras capable of identifying an object the size of a milk carton from altitudes of 60,000 feet.

The U-2 has repeatedly been considered for retirement in favour of drones. In 2011, the USAF revealed plans to replace the U-2 with the RQ-4 Global Hawk, a UAV, within four years; however, in January 2012, it was instead decided to extend the U-2's service life. Critics have pointed out that the RQ-4's cameras and sensors are less capable and lack all-weather operating capability; however, some of the U-2's sensors could be installed on the RQ-4. In late 2014, Lockheed Martin proposed converting the manned U-2 fleet into UAVs, which would substantially bolster its payload capability; however, the USAF declined to provide funding for such an extensive conversion.

During the 2010s, American defense conglomerate Lockheed Martin promoted its proposal to develop a hypersonic UAV, which it referred to the SR-72 in allusion to its function as a spiritual successor to the retired SR-71 Blackbird. The company has also developed several other reconnaissance UAVs, such as the Lockheed Martin RQ-170 Sentinel.

Technologies

Miniature UAVs

Due to the low cost of miniature UAVs, this technology brings aerial reconnaissance into the hands of soldiers on the ground. The soldier on the ground can both control the UAV and see its output, yielding great benefit over a disconnected approach. With small systems being man packable, operators are now able to deploy air assets quickly and directly. The low cost and ease of operation of these miniature UAVs has enabled forces such as the Libyan Rebels to use miniature UAVs.

Aeryon Scout VTOL UAV

Low cost miniature UAVs demand increasingly miniature imaging payloads. Developments in miniature electronics have fueled the development of increasingly capable surveillance payloads, allowing miniature UAVs to provide high levels of capability in never before seen packages.

Reconnaissance pods

Reconnaissance pods can be carried by fighter-bomber aircraft. Examples include the British Digital Joint Reconnaissance Pod (DJRP); Chinese KZ900; UK RAPTOR; and the US Navy's F-14 Tomcat Tactical Airborne Reconnaissance Pod System (TARPS). Some aircraft made for non-military applications also have reconnaissance pods, i.e. the Qinetiq Mercator.

India–United States relations

Prime Minister Narendra Modi with President Joe Biden at the White House, September 2021.

Relations between India and the United States date back to India's independence movement and have continued well after independence from the United Kingdom in 1947. Currently, India and the United States enjoy close relations and have often seen eye-to-eye on issues such as counterterrorism (including concern of Pakistan's involvement), and share mutual distrust on Pakistan's nuclear weapons program, and Chinese influence in the Indo-Pacific.

In 1954, the United States made Pakistan a Central Treaty Organization (CENTO) treaty-ally. India cultivated strategic and military relations with the Soviet Union to counter Pakistan–United States relations. In 1961, India became a founding member of the Non-Aligned Movement to avoid involvement in the Cold War power-play between the United States and the Soviet Union. The Nixon administration's support for Pakistan during the Indo-Pakistani War of 1971 affected relations until the dissolution of the Soviet Union in 1991. In the 1990s, Indian foreign policy adapted to the unipolar world and developed closer ties with the United States.

In the twenty-first century, Indian foreign policy has sought to leverage India's strategic autonomy in order to safeguard sovereign rights and promote national interests within a multi-polar world. Under the administrations of Presidents George W. Bush (2001–2009) and Barack Obama (2009–2017), the United States of America has demonstrated accommodation to India's core national interests and acknowledged outstanding concerns. Increase in bilateral trade & investment, co-operation on global security matters, inclusion of India in decision-making on matters of global governance (United Nations Security Council), upgraded representation in trade & investment forums (World Bank, IMF, APEC), admission into multilateral export control regimes (MTCR, Wassenaar Arrangement, Australia Group) and support for admission in the Nuclear Suppliers Group and joint-manufacturing through technology sharing arrangements have become key milestones and a measure of speed and advancement on the path to closer US–India relations. In 2016, India and the United States signed the Logistics Exchange Memorandum of Agreement and India was declared a Major Defense Partner of the United States. In 2020, India provided its agreement for terminating an export embargo on a medicinal drug known as hydroxychloroquine amidst the combat against the ongoing coronavirus (COVID-19) pandemic, after Trump threatened retaliation against India, if it did not comply with terminating the export embargo on hydroxychloroquine. The relationship was briefly shaken in the early stages of the Biden administration after a plea by Adar Poonawalla, CEO of Serum Institute of India to lift the embargo on export of raw materials needed to ramp up production of COVID-19 vaccines, was rejected.

According to Gallup's annual World Affairs survey, India is perceived by Americans as their sixth favorite nation in the world, with 71% of Americans viewing India favorably in 2015. Gallup polls found that 74% of Americans viewed India favorably in 2017, 72% in 2019, and 75% in 2020.

According to a Morning Consult poll conducted in August 2021 after the fall of Afghanistan, 79% of Indians viewed the United States favorably, compared to 10% who viewed the United States unfavorably, the highest percentage out of all 15 major countries surveyed, more favorable than how most Americans viewed the United States.

In 2017, bilateral trade (in both goods & services) grew by 9.8% to reach US$126,100,000,000. India's exports to the US stood at US$76,700,000,000 while USA's exports to India stood at US $49,400,000,000.

History

American Revolution and the East India Company

Great Britain and France had territories in the Americas as well as the Indian subcontinent. In 1778, when France declared war against Britain, fighting broke out between British and French colonies in India. This marked the beginning of the Second Anglo-Mysore War. Hyder Ali, the Sultan of the Kingdom of Mysore, allied himself with the French. From 1780 to 1783, Franco-Mysorean forces fought in several campaigns against the British in western and southern India, in several places such as Mahé and Mangalore.

On June 29, with both sides weakened, the British dispatched HMS Medea to surrender, with letters to the French stating the American Revolutionary War was over. The Treaty of Paris was drafted on 30 November 1782, months before the Siege of Cuddalore but news did not reach India until seven months later, due to the delay of communications to India. The Treaty of Paris was finally signed on 3 September 1783 and was ratified by the U.S. Congress a few months later. Under the terms of the treaty, Britain returned Pondicherry back to the French and Cuddalore was returned to the British.

The flag of the East India Company is said to have inspired the Grand Union Flag of 1775, ultimately inspiring the current flag of the United States, as both flags were of the same design. Mysorean rockets were also used in the Battle of Baltimore, and are mentioned in "The Star-Spangled Banner", the national anthem of the United States: And the rockets' red glare, the bombs bursting in air.

Under British Raj (1858-1947)

The relationships between India in the days of the British Raj and the United States were thin. Swami Vivekananda promoted Yoga and Vedanta in the United States at the World's Parliament of Religions in Chicago, during the World's Fair in 1893. Mark Twain visited India in 1896 and described it in his travelogue Following the Equator with both revulsion and attraction before concluding that India was the only foreign land he dreamed about or longed to see again. Regarding India, Americans learned more from English writer Rudyard Kipling. Mahatma Gandhi had an important influence on the philosophy of non-violence promoted by American civil rights movement leader Martin Luther King Jr. in the 1950s.

In the 1930s and early-1940s, Roosevelt voiced strong support to the Indian independence movement despite being allies with Britain. The first significant immigration from India before 1965 involved Sikh farmers going to California in the early-twentieth century.

During World War II

During World War II, India became the main base for the American China Burma India Theater (CBI) in the war against Japan. Tens of thousands of American servicemen arrived, bringing all sorts of advanced technology, and currency; they left in 1945. Serious tension erupted over American demands, led by US President Franklin D. Roosevelt, that India be given independence, a proposition Churchill vehemently rejected. For years, Roosevelt had encouraged British disengagement from India. The American position was based on an opposition to Europeans having colonies and a practical concern for the outcome of the war, and the expectation of a large American role in a post-independence era. Churchill threatened to resign if Roosevelt continued to push his case, causing Roosevelt to back down. Meanwhile, India became the main American staging base to fly aid to China. During World War II, the Panagarh Airport in the state of West Bengal in India was used as a supply transport airfield from 1942 to 1945 by the United States Army Air Forces Tenth Air Force and as a repair and maintenance depot for B-24 Liberator heavy bombers by Air Technical Service Command.

Independence (1947–1997)

US President Harry S. Truman and Indian Prime Minister Jawaharlal Nehru in Washington, 1949, with Nehru's sister, Vijayalakshmi Pandit Indian ambassador to the United States.

The United States under the Truman administration leaned towards favouring India in the late-1940s as a consequence of most U.S. planners seeing India more valuable diplomatically than neighboring Pakistan. However, during the Cold War Nehru's policy of neutrality was cumbersome to many American observers. American officials perceived India's policy of non-alignment negatively. Ambassador Henry F. Grady told then-Indian Prime Minister Jawaharlal Nehru that the United States did not consider neutrality to be an acceptable position. Grady told the State Department in December 1947 that he had informed Nehru "that this is a question that cannot be straddled and that India should get on the democratic side immediately". In 1948, Nehru rejected American suggestions for resolving the Kashmir crisis via third party mediation.

Nehru's 1949 tour of the United States was "an undiplomatic disaster" that left bad feelings on both sides. Nehru and his top aide V. K. Krishna Menon discussed whether India should "align with United States 'somewhat' and build up our economic and military strength." The Truman administration was quite favorable and indicated it would give Nehru anything he asked for. Nehru refused, and thereby forfeited the chance for a gift of one million tons of wheat. The American Secretary of State Dean Acheson recognized Nehru's potential world role but added that he was "one of the most difficult men with whom I have ever had to deal." The American visit had some benefits in that Nehru gained widespread understanding and support for his nation, and he himself gained a much deeper understanding of the American outlook.

India rejected the American advice that it should not recognize the Communist conquest of China, but it did back the US when it supported the 1950 United Nations resolution condemning North Korea's aggression in the Korean War. India tried to act as a mediator to help end the war, and served as a conduit for diplomatic messages between the US and China. Although no Indian troops took part in the war, India did send a Medical Corps of 346 army doctors to help the UN side. Meanwhile, poor harvests forced India to ask for American aid for its food security, which was given starting in 1950. In the first dozen years of Indian independence (1947–59), the US provided $1,700,000,000 in aid; including $931,000,000 in food. The Soviet Union provided about half as much in monetary terms, however made much larger contributions in kind, taking the form of infrastructural aid, soft loans, technical knowledge transfer, economic planning and skills involved in the areas of steel mills, machine building, hydroelectric power and other heavy industries- especially nuclear energy and space research. In 1961, the US pledged $1,000,000,000 in development loans, in addition to $1,300,000,000 of free food.

To ease the tensions Eisenhower sent John Sherman Cooper as ambassador in 1956–1957. Cooper got along very well with Nehru.

In terms of rhetoric, Jawaharlal Nehru—as both prime minister and foreign minister (1947–1964), promoted a moralistic rhetoric attacking both the Soviet bloc and the U.S. and its bloc. Instead Nehru tried to build a nonaligned movement, paying special attention to the many new nations in the Third World released from European colonial status at this time. President Dwight D. Eisenhower and his Secretary of State John Foster Dulles themselves used moralistic rhetoric to attack the evils of Communism.

In 1959, Eisenhower became the first US president to visit India to strengthen the staggering ties between the two nations. He was so supportive that the New York Times remarked, "It did not seem to matter much whether Nehru had actually requested or been given a guarantee that the US would help India to meet further Chinese Communist aggression. What mattered was the obvious strengthening of Indian–American friendship to a point where no such guarantee was necessary."

During John F. Kennedy's Presidency (1961–63), India was considered a strategic partner and counterweight to the rise of Communist China. Kennedy said,

Chinese Communists have been moving ahead the last 10 years. India has been making some progress, but if India does not succeed with her 450 million people, if she can't make freedom work, then people around the world are going to determine, particularly in the underdeveloped world, that the only way they can develop their resources is through the Communist system.

The Kennedy administration openly supported India during the 1962 Sino-Indian war and considered the Chinese action as "blatant Chinese Communist aggression against India". The United States Air Force flew in arms, ammunition and clothing supplies to the Indian troops and the United States Navy sent the USS Kitty Hawk aircraft carrier from the Pacific Ocean to India, only to be recalled before it reached the Bay of Bengal. In a May 1963 National Security Council meeting, the United States discussed contingency planning that could be implemented in the event of another Chinese aggression on India. Defense Secretary Robert McNamara and General Maxwell Taylor advised the president to use nuclear weapons should the Americans intervene in such a situation. Kennedy insisted that Washington defend India as it would any ally, saying, "We should defend India, and therefore we will defend India." Kennedy's ambassador to India was the noted liberal economist John Kenneth Galbraith, who was considered close to India. While in India, Galbraith helped establish one of the first Indian computer science departments, at the Indian Institute of Technology in Kanpur, Uttar Pradesh. As an economist, he also presided over the (at the time) largest US foreign aid program to any country.

Following the assassination of Kennedy in 1963, India-US relations deteriorated gradually. While Kennedy's successor Lyndon B. Johnson sought to maintain relations with India to counter Communist China, he also sought to strengthen ties with Pakistan with the hopes of easing tensions with China and weakening India's growing military buildup as well. Relations then hit an all-time low under the Nixon administration in the early 1970s.Nixon shifted away from the neutral stance which his predecessors had taken towards India-Pakistan hostilities. He established a very close relationship with Pakistan, aiding it militarily and economically, as India, now under the leadership of Indira Gandhi, was leaning towards Soviet Union. He considered Pakistan as a very important ally to counter Soviet influence in the Indian subcontinent and establish ties with China, with whom Pakistan was very close. The frosty personal relationship between Nixon and Indira further contributed to the poor relationship between the two nations. During the 1971 Indo-Pakistani War, the US openly supported Pakistan and deployed its aircraft carrier USS Enterprise towards the Bay of Bengal, which was seen as a show of force by the US in support of the West Pakistani forces. Later in 1974, India conducted its first nuclear test, Smiling Buddha, which was opposed by the US, however it also concluded that the test did not violate any agreement and proceeded with a June 1974 shipment of enriched uranium for the Tarapur reactor.

In the late 1970s, with the Janata Party leader Morarji Desai becoming the Prime Minister, India improved its relations with the US, led by Jimmy Carter, despite the latter signing an order in 1978 barring nuclear material from being exported to India due to India's non-proliferation record.

Despite the return of Indira Gandhi to power in 1980, the relations between the two countries continued to improve gradually, although India did not support the United States in its role in the Soviet invasion and occupation of Afghanistan. Indian foreign minister P. V. Narasimha Rao expressed "grave concern" over the United States's decision to "rearm" Pakistan; the two countries were working closely together to counter the Soviets in Afghanistan. The Reagan Administration led by US President Ronald Reagan provided limited assistance to India. India sounded out Washington on the purchase of a range of US defence technology, including F-5 aircraft, super computers, night vision goggles and radars. In 1984 Washington approved the supply of selected technology to India including gas turbines for naval frigates and engines for prototypes for India's light combat aircraft. There were also unpublicised transfers of technology, including the engagement of a US company, Continental Electronics, to design and build a new VLF communications station at Tirunelveli in Tamil Nadu, which was commissioned in the late 1980s.

Under Bill Clinton (President 1993–2001) and P. V. Narasimha Rao (Prime Minister 1991–1996) both sides mishandled relations, according to Arthur G. Rubinoff. Clinton simultaneously pressured India to liberalize its economy while criticizing New Delhi on human rights and nuclear issues. In the face of criticism from Washington and opposition at home, Indian leaders lost their enthusiasm for rapprochement and reverted to formalistic protocol over substantive diplomacy. The Brown Amendment that restored American aid to Pakistan in 1995 was an irritant. In returning to a Cold War style rhetoric, Indian parliamentarians and American congressmen demonstrated their unwillingness to establish a new relationship.

NDA I and II governments (1998–2004)

Soon after Atal Bihari Vajpayee became Indian Prime Minister, he authorised nuclear weapons testing at Pokhran. The United States strongly condemned this testing, promised sanctions, and voted in favour of a United Nations Security Council Resolution condemning the tests. President Bill Clinton imposed economic sanctions on India, including cutting off all military and economic aid, freezing loans by American banks to state-owned Indian companies, prohibiting loans to the Indian government for all except food purchases, prohibiting American aerospace technology and uranium exports to India, and requiring the US to oppose all loan requests by India to international lending agencies. However, these sanctions proved ineffective – India was experiencing a strong economic rise, and its trade with the US only constituted a small portion of its GDP. Only Japan joined the US in imposing direct sanctions, while most other nations continued to trade with India. The sanctions were soon lifted. Afterward, the Clinton administration and Prime Minister Vajpayee exchanged representatives to help rebuild relations.

India emerged in the 21st century as increasingly vital to core US foreign policy interests. India, a dominant actor in its region, and the home of more than one billion citizens, is now often characterised as a nascent Great Power and an "indispensable partner" of the US, one that many analysts view as a potential counterweight to the growing clout of China.

In March 2000, U.S. President Bill Clinton visited India, undertaking bilateral and economic discussions with Prime Minister Vajpayee. During the visit, the Indo-US Science & Technology Forum was established.

Over the course of improved diplomatic relations with the Bush Administration, India agreed to allow close international monitoring of its nuclear weapons development, although it has refused to give up its current nuclear arsenal. In 2004, the US decided to grant Major non-NATO ally (MNNA) status to Pakistan. The US extended the MNNA strategic working relationship to India but the offer was turned down.

After the September 11 attacks against the US in 2001, President George W. Bush collaborated closely with India in controlling and policing the strategically critical Indian Ocean sea lanes from the Suez Canal to Singapore.

UPA I & II governments (2004–2014)

During the tenure of the George W. Bush administration, relations between India and the United States were seen to have blossomed, primarily over common concerns regarding growing Islamic extremism, energy security, and climate change. George W. Bush commented, "India is a great example of democracy. It is very devout, has diverse religious heads, but everyone is comfortable about their religion. The world needs India". Fareed Zakaria, in his book The Post-American World, described George W. Bush as "being the most pro-Indian president in American history." Similar sentiments are echoed by Rejaul Karim Laskar, a scholar of Indian foreign policy and ideologue of Indian National Congress – the largest constituent of the UPA. According to Laskar, the UPA rule has seen a "transformation in bilateral ties with the US", as a result of which the relations now covers "a wide range of issues, including high technology, space, education, agriculture, trade, clean energy, counter-terrorism, etc".

After the December 2004 tsunami, the US and Indian navies cooperated in search and rescue operations and in the reconstruction of affected areas.

Since 2004, Washington and New Delhi have been pursuing a "strategic partnership" that is based on shared values and generally convergent geopolitical interests. Numerous economic, security, and global initiatives – including plans for civilian nuclear cooperation – are underway. This latter initiative, first launched in 2005, reversed three decades of American non-proliferation policy. Also in 2005, United States and India signed a ten-year defense framework agreement, with the goal of expanding bilateral security cooperation. The two countries engaged in numerous and unprecedented combined military exercises, and major US arms sales to India were concluded. An Open Skies Agreement was signed in April 2005, enhancing trade, tourism, and business via the increased number of flights, and Air India purchased 68 US Boeing aircraft at a cost of $8 billion. The United States and India also signed a bilateral Agreement on Science and Technology Cooperation in 2005. After Hurricane Katrina, India donated $5 million to the American Red Cross and sent two planeloads of relief supplies and materials to help. Then, on 1 March 2006, President Bush made another diplomatic visit to further expand relations between India and the U.S.

Indian Minister of External Affairs Pranab Mukherjee with US President George W. Bush, March 2008

The value of all bilateral trade tripled from 2004 to 2008 and continues to grow, while significant two-way investment also grows and flourishes.

The influence of a large Indian-American community is reflected in the largest country-specific caucus in the United States Congress, while between 2009 and 2010 more than 100,000 Indian students have attended American colleges and universities.

In November 2010, President Barack Obama visited India and addressed a joint session of the Indian Parliament, where he backed India's bid for a permanent seat on the United Nations Security Council.

Strategic and military determinants

In March 2009, the Obama Administration cleared the US$2.1 billion sale of eight P-8 Poseidons to India. This deal, and the $5 billion agreement to provide Boeing C-17 military transport aircraft and General Electric F414 engines announced during Obama's November 2010 visit, makes the US one of the top three military suppliers to India (after Israel and Russia). Indians have raised concerns about contract clauses forbidding the offensive deployment of these systems. India is trying to resolve performance-related issues on the Boeing P-8I that have already been delivered to India.

US Chairman of the Joint Chiefs of Staff Mike Mullen has encouraged stronger military ties between India and the United States, and said that "India has emerged as an increasingly important strategic partner [of the US]". US Undersecretary of State William Joseph Burns also said, "Never has there been a moment when India and America mattered more to each other." The Deputy Secretary of Defence, Ashton Carter, during his address to the Asia Society in New York on August 1, 2012, said that India–US relationship has a global scope, in terms of the reach and influence of both countries. He also said that both countries are strengthening the relations between their defence and research organisations.

Revelations about US spying operations against India

India, in July and November 2013, demanded that the US respond to revelations that the Indian UN mission in New York City and the Indian Embassy in Washington had been targeted for spying.

On 2 July 2014, U.S. diplomats were summoned by the Indian Ministry of External Affairs to discuss allegations that the National Security Agency had spied upon private individuals and political entities within India. A 2010 document leaked by Edward Snowden and published by the Washington Post revealed that US intelligence agencies had been authorized to spy on the Indian Prime Minister Narendra Modi (who was then the Chief Minister of Gujarat).

WikiLeaks revelations that Western intelligence agencies have used foreign aid workers and staff at NGOs as non-official cover prompted the Government of India to step-up the monitoring of satellite phones and movement of personnel working for humanitarian relief organisations and development aid agencies in the vicinity of sensitive locations.

Foreign policy issues

According to some analysts, India–U.S. relations have been strained over the Obama administration's approach to Pakistan and the handling of the Taliban insurgency in Afghanistan. India's National Security Adviser, M.K. Narayanan, criticised the Obama administration for linking the Kashmir dispute to the instability in Pakistan and Afghanistan, and said that by doing so, President Obama was "barking up the wrong tree." Foreign Policy in February 2009 also criticised Obama's approach to South Asia, saying that "India can be a part of the solution rather than part of the problem" in South Asia. It also suggested that India take a more proactive role in rebuilding Afghanistan, irrespective of the attitude of the Obama Administration. In a clear indication of growing rift between the two countries, India decided not to accept a US invitation to attend a conference on Afghanistan at the end of February 2009. Bloomberg has also reported that, since the 2008 Mumbai attacks, the public mood in India has been to pressure Pakistan more aggressively to take actions against the culprits behind the terrorist attack, and that this might reflect on the upcoming Indian general elections in May 2009. Consequently, the Obama Administration may find itself at odds with India's rigid stance against terrorism.

India and US governments have differed on a variety of regional issues ranging from India's cordial relations with Iran and Russia to foreign policy disagreements relating to Sri Lanka, Maldives, Myanmar and Bangladesh.

Robert Blake, Assistant Secretary of State for South and Central Asian Affairs, dismissed any concerns over a rift with India regarding American AfPak policy. Calling India and the United States "natural allies", Blake said that the United States cannot afford to meet the strategic priorities in Pakistan and Afghanistan at "the expense of India".

India criticised the Obama Administration's decision to limit H-1B (temporary) visas, and India's then External Affairs Minister Pranab Mukherjee (later, the President of India until 2017) said that his country would oppose US "protectionism" at various international forums. India's Commerce Minister, Kamal Nath, said that India may move against Obama's outsourcing policies at the World Trade Organization. However, the outsourcing advisory head of KPMG said that India had no reason to worry, since Obama's statements were directed against "outsourcing being carried out by manufacturing companies" and not outsourcing of IT-related services.

In May 2009, Obama reiterated his anti-outsourcing views and criticised the current US tax policy "that says you should pay lower taxes if you create a job in Bangalore, India, than if you create one in Buffalo, New York." However, during the US India Business Council meeting in June 2009, U.S. Secretary of State Hillary Clinton advocated for stronger economic ties between India and the United States. She also rebuked protectionist policies, saying that "[United States] will not use the global financial crisis as an excuse to fall back on protectionism. We hope India will work with us to create a more open, equitable set of opportunities for trade between our nations."

President Barack Obama, Secretary of State Hillary Clinton, and the Indian delegation at the U.S.-India Strategic Dialogue reception at the Department of State in Washington, D.C., 2010.

In June 2010, the United States and India formally re-engaged the US-India Strategic Dialogue initiated under President Bush when a large delegation of high-ranking Indian officials, led by External Affairs Minister S.M. Krishna, visited Washington, D.C. As leader of the US delegation, Secretary of State Clinton lauded India as "an indispensable partner and a trusted friend". President Obama appeared briefly at a United States Department of State reception to declare his firm belief that America's relationship with India "will be one of the defining partnerships of the 21st century." The Strategic Dialogue produced a joint statement in which the two countries pledged to "deepen people-to-people, business-to-business, and government-to-government linkages ... for the mutual benefit of both countries and for the promotion of global peace, stability, economic growth and prosperity." It outlined extensive bilateral initiatives in each of ten key areas: (1) advancing global security and countering terrorism, (2) disarmament and nonproliferation, (3) trade and economic relations, (4) high technology, (5) energy security, clean energy, and climate change, (6) agriculture, (7) education, (8) health, (9) science and technology, and (10) development.

In November 2010, Obama became the second US President (after Richard Nixon in 1969) to undertake a visit to India in his first term in office. On 8 November, Obama also became the second US President (after Dwight D. Eisenhower in 1959) to ever address a joint session of the Parliament of India. In a major policy shift, Obama declared US support for India's permanent membership on the UN Security Council. Calling the India–U.S. relationship "a defining partnership of the 21st century", he also announced the removal of export control restrictions on several Indian companies, and concluded trade deals worth $10 billion, which are expected to create and/or support 50,000 jobs in the US.

Devyani Khobragade incident

In December 2013, Devyani Khobragade, the Deputy Consul General of India in New York, was arrested and accused by U.S. federal prosecutors of submitting false work visa documents for her housekeeper and paying the housekeeper "far less than the minimum legal wage." The ensuing incident caused protests from the Indian government and a rift in India–United States relations; Indians expressed outrage that Khobragade was strip-searched (a routine practice for all persons arrested by the U.S. Marshals Service) and held in the general inmate population. Former Prime Minister Manmohan Singh said that Khobragade's treatment was "deplorable".

India demanded an apology from the U.S. over her alleged "humiliation" and called for the charges to be dropped, which the U.S. declined to do. The Indian government retaliated for what it viewed as the mistreatment of its consular official by revoking the ID cards and other privileges of U.S. consular personnel and their families in India and removing security barriers in front of the U.S. Embassy in New Delhi.

The Indian government also blocked non-diplomats from using the American Community Support Association (ACSA) club and American Embassy Club in New Delhi, ordering these social clubs to cease all commercial activities benefiting non-diplomatic personnel by 16 January 2014. The ACSA club operates a bar, bowling alley, swimming pool, restaurant, video-rentals club, indoor gym and a beauty parlour within the embassy premises. Tax-free import clearances given to US diplomats and consular officials for importing food, alcohol and other domestic items were revoked with immediate effect. U.S. embassy vehicles and staff are no longer immune from penalties for traffic violations. American diplomats were asked to show work contracts of all domestic help (cooks, gardeners, drivers and security staff) employed within their households. Indian authorities also conducted an investigation into the American Embassy School.

Khobragade was subject to prosecution at the time of her arrest because she had only consular immunity (which gives one immunity from prosecution only for acts committed in connection with official duties) and not the more extensive diplomatic immunity. After her arrest, the Indian government moved Khobragade to the Indian mission to the United Nations, upgrading her status and conferring diplomatic immunity on her; as a result, the federal indictment against Khobragade was dismissed in March 2014, although the door was left open to refiling of charges. A new indictment was filed against Khobragade, but by that point she had left the country. (In an effort to resolve the dispute, the U.S. State Department had told Khobragade to leave the country).

Nancy J. Powell, the U.S. ambassador to India, resigned following the incident, which was widely seen by India "as fallout from the imbroglio." Some commentators suggested that the incident and response could lead to wider damage in U.S.–India relations. Former Finance Minister Yashwant Sinha called for the arrest of same-sex companions of US diplomats, citing the Supreme Court of India's upholding of Section 377 of the Indian Penal Code whereby homosexuality is illegal in India. Former State Department legal advisor John Bellinger questioned whether the decision to arrest and detain Khobragade was "wise policy ... even if technically permissible" under the Vienna Convention on Consular Relations, while Robert D. Blackwill, the former U.S. ambassador to India from 2001 to 2003, said the incident was "stupid." Nevertheless, within a year of the incident, U.S.-India relations were warming again, as U.S. President Obama visited India in January 2015.

Speaking at Harvard Law School in 2014, U.S. Attorney in Manhattan Preet Bharara, in the Khobragade case, said: "(It was) not the crime of the century but a serious crime nonetheless, that is why the State Department opened the case, that is why the State Department investigated it. That is why career agents in the State Department asked career prosecutors in my office to approve criminal charges." Bharara, who was born in India, said that he was upset by attacks on him in the Indian press.

Khobragade was originally a highly sympathetic figure in India, as Indians viewed her arrest as an affront to national dignity. Opinions in India shifted, however, after Khobragade was the subject of two inquiries by the Indian government. One internal investigation found that Khobragade had violated regulations "by failing to inform the government that her children had been issued American passports" and resulted in Khobragade being administratively disciplined; a second inquiry was held into Khobragade's series of interviews about the case, undertaken without authorization from the Ministry of External Affairs.

Relationship between US Government and Narendra Modi (2001–2014)

Sectarian violence during the 2002 Gujarat riots damaged relations between the US Government and Narendra Modi, then incumbent Chief Minister of Gujarat. Human rights activists accused Modi of fostering anti-Muslim violence. New-York based NGO Human Rights Watch, in their 2002 report directly implicated Gujarat state officials in the violence against Muslims.

In 2012, a Special Investigation Team (SIT) appointed by the Indian Supreme Court found no "prosecutable evidence" against Modi. The Supreme Court of India absolved Narendra Modi of any criminal wrongdoing during the 2002 Gujarat riots.

In 2005, the US Department of State used a 1998 International Religious Freedom Act (IRFA) provision to revoke Modi's tourist/business visa citing section 212 (a) (2) (g) of the US Immigration and Nationality Act. The IRFA provision "makes any foreign government official who 'was responsible for or directly carried out, at any time, particularly severe violations of religious freedom' ineligible for a visa to the United States."

David C. Mulford, the US Ambassador to India from 2003 to 2009, justified the rejection of a diplomatic visa to Modi in a statement released on 21 March 2005 stating that the US State Department re-affirmed the original decision to revoke Modi's tourist/business visa to which India's highest judiciary abstained all the charges from Modi later on the particular issue:

This decision applies to Mr. Narendra Modi only. It is based on the fact that, as head of the State government in Gujarat between February 2002 and May 2002, he was responsible for the performance of state institutions at that time. The State Department's detailed views on this matter are included in its annual Country Reports on Human Rights Practices and the International Religious Freedom Report. Both reports document the violence in Gujarat from February 2002 to May 2002 and cite the Indian National Human Rights Commission report, which states there was "a comprehensive failure on the part of the state government to control the persistent violation of rights of life, liberty, equality, and dignity of the people of the state."

Prior to Narendra Modi becoming the Prime Minister of India, the US Government had made it known that Modi as Chief Minister of Gujarat would not be permitted to travel to the US. Michael Kugelman of the Wilson Center opined that although technically speaking there was no US 'visa ban' from 2005 to 2014, the US government policy of considering Modi as persona non grata had resulted in a de facto travel-ban. After the US revoked his existing B1/B2 visa in 2005 and refused to accept his application for an A2 visa, the US State Department affirmed that the visa policy remained unchanged : "(Mr Modi) is welcome to apply for a visa and await a review like any other applicant".

Exploring opportunities on how to move the relationship out of a state of morose, Lisa Curtis, senior research fellow for South Asia in the Asian Studies Center of the Heritage Foundation, says that "the U.S. must first signal its willingness and commitment to collaborating with the new government—and that it will not dwell on the controversy of the 2002 Gujarat riots, which led the U.S. to revoke Modi's visa in 2005."

In 2009, the US Commission for International Religious Freedom (USCIRF) report after ignoring the views and decision of independent body (SIT) set up by India's highest judiciary vehemently alleged that there was "significant evidence" linking Narendra Modi to communal riots in the state in 2002 and asked the Obama administration to continue the policy of preventing him from travelling to the United States of America.

The Obama administration maintained the 2005 decision taken by the George W. Bush administration to deny Narendra Modi entry into the United States of America. The US Government says that Modi can circumvent the USCIRF sanctions regime by visiting Washington on a Heads of government A1-visa as long as he is the Prime Minister of India. According to US State Department Spokesperson, Jen Psaki : "US law exempts foreign government officials, including heads of state and heads of government from certain potential inadmissibility grounds". The visa refusal came after some Indian-American groups and human rights organizations with political view campaigned against Modi, including the Coalition Against Genocide.

On 11 June 2014, Robert Blackwill, the former Coordinator for Strategic Planning and Deputy US National Security Advisor during the presidency of George W. Bush, spoke at length about India–U.S. relations and said : "Mr Modi is a determined leader. He is candid and frank. I also worked with him during the Gujarat earthquake when I was posted as (the US) ambassador to India. ... It was mistake by the current Obama administration to delay engagement with Mr Modi. I do not know why they did so but definitely, this did not help in building relationship. ... The old formula and stereotypes will not work if the US administration wants to engage with Mr Modi. The Indian prime minister is candid, direct and smart. He speaks his mind. The US administration also has to engage in candid conversation when Mr Modi meets President Obama later this year. They have to do something innovative to engage with him."

Nicholas Burns, former U.S. Undersecretary of State for Political Affairs from 2005 to 2008, has spoken about the visa denial by saying: "Bush administration officials, including me, believed this to be the right decision at the time." and has opined that "Now that it looks like Modi will become prime minister, it's reasonable for the Obama administration to say it's been 12 years [since the 2002 riots], and we'll be happy to deal with him"

NDA government (2014–present)

India–United States relations have improved significantly during the Premiership of Narendra Modi since 2014. At present, India and the US share an extensive and expanding cultural, strategic, military, and economic relationship which is in the phase of implementing confidence building measures (CBM) to overcome the legacy of trust deficit – brought about by adversarial US foreign policies and multiple instances of technology denial – which have plagued the relationship over several decades. Unrealistic expectations after the conclusion of the 2008 U.S.–India Civil Nuclear Agreement (which underestimated negative public opinion regarding the long-term viability of nuclear power generation and civil-society endorsement for contractual guarantees on safeguards and liability) has given way to pragmatic realism and refocus on areas of cooperation which enjoy favourable political and electoral consensus.

Key recent developments include the rapid growth of India's economy, closer ties between the Indian and American industries especially in the Information and communications technology (ICT), engineering and medical sectors, an informal entente to manage an increasingly assertive China, robust cooperation on counter-terrorism, the deterioration of U.S.-Pakistan relations, easing of export controls over dual-use goods & technologies (99% of licenses applied for are now approved), and reversal of long-standing American opposition to India's strategic program.

Income creation in the USA through knowledge-based employment by Asian Indians has outpaced every other ethnic group according to U.S. Census data. Growing financial and political clout of the affluent Asian Indian diaspora is noteworthy. Indian American households are the most prosperous in the US with a median revenue of US$100,000 and are followed by Chinese Americans at US$65,000. The average household revenue in the USA is US$63,000.

The US and India continue to differ on issues ranging from trade to civil liberties. The Indian Home Ministry, through an affidavit submitted to the Delhi High Court on 13 February 2015, claimed that Country Reports on Rights & Practices have become instruments of foreign policy: "The US, UK and EU have clearly mentioned in government documents and pronouncements that these reports are made for the purpose of their being used as instruments of foreign policy." The affidavit also claimed that the reports by US, UK and European Parliament were biased since they "do not provide opportunity to the Government of India or the local embassy/high commission to record their opinion and are heavily biased against the targeted country". The 2014 State Department's annual Trafficking in Persons (TIP) report appeared to classify the Khobragade incident as an example of human trafficking, stating: "An Indian consular officer at the New York consulate was indicted in December 2013 for visa fraud related to her alleged exploitation of an Indian domestic worker." In response, India has shown no urgency to allow visits to India by the newly appointed US anti-human trafficking ambassador Susan P. Coppedge and the US special envoy for LGBT rights Randy Berry. Under Section 377 of the Indian Penal Code homosexuality was illegal in India. Indian Ambassador to the US, Arun K. Singh reiterated India's commitment to work within an international framework to tackle the problem of trafficking but rejected any "unilateral assessments" by another country saying "We will never accept it" and downplayed the importance of the visits: "When you ask a U.S. official when somebody will be given a visa, they always say 'we will assess when visa is applied for.' ... I can do no better than to reiterate the U.S. position."

In February 2016, the Obama administration notified the US Congress that it intended to provide Pakistan eight nuclear-capable F-16 fighters and assorted military goods including eight AN/APG-68(V)9 airborne radars and eight ALQ-211(V)9 electronic warfare suites despite strong reservations from US lawmakers regarding the transfer of any nuclear weapons capable platforms to Pakistan. Shashi Tharoor, an elected representative from the Congress party in India, questioned the substance of India–U.S. ties: "I am very disappointed to hear this news. The truth is that continuing to escalate the quality of arms available to an irresponsible regime that has sent terrorists to India, and in the name of anti-terrorism, is cynicism of the highest order". The Indian Government summoned the US Ambassador to India to convey its disapproval regarding the sale of F-16 fighter jets to Pakistan.

Relationship under President Trump (2017-2021)

Indian Prime Minister Narendra Modi with US President Donald Trump at the 45th G7 in Biarritz, August 2019.

In February 2017, Indian ambassador to the U.S. Navtej Sarna hosted a reception for the National Governors Association (NGA), which was attended by the Governors of 25 states and senior representatives of 3 more states. This was the first time such an event has occurred. Explaining the reason for the gathering, Virginia Governor and NGA Chair Terry McAuliffe stated that "India is America's greatest strategic partner". He further added, "We clearly understand the strategic importance of India, of India–U.S. relations. As we grow our 21st century economy, India has been so instrumental in helping us build our technology, medical professions. We recognise a country that has been such a close strategic ally of the US. That's why we the Governors are here tonight." McAuliffe, who has visited India 15 times, also urged other Governors to visit the country with trade delegations to take advantage of opportunities.

In October 2018, India inked the historic agreement worth US$5.43 billion with Russia to procure four S-400 Triumf surface-to-air missile defence system, one of the most powerful missile defence systems in the world ignoring America's CAATSA act. The U.S. threatened India with sanctions over India's decision to buy the S-400 missile defense system from Russia. The United States also threatened India with sanctions over India's decision to buy oil from Iran. According to the President of the U.S.-India Strategic Partnership Forum (USISPF), Mukesh Aghi: "sanctions would have a disastrous effect on U.S.-India relations for decades to come. In India’s eyes, the United States would once again be regarded as untrustworthy."

In June 2020, during the George Floyd protests, the Mahatma Gandhi Memorial in Washington, D.C. was vandalised by unknown miscreants on the intervening night of June 2 and 3. The incident prompted the Indian Embassy to register a complaint with law enforcement agencies. Taranjit Singh Sandhu, the Indian Ambassador to the United States called the vandalism "a crime against humanity". U.S. President Donald Trump called the defacement of Mahatma Gandhi's statue a "disgrace".

On 21 December 2020, President of the United States Donald Trump awarded Modi with the Legion of Merit for elevating India–United States relations. The Legion of Merit was awarded to Modi along with Prime Minister of Australia Scott Morrison and former Prime Minister of Japan Shinzo Abe, the "original architects" of the QUAD.

Modi–Biden relationship (2021 onwards)

Optimism reigns as Joe Biden takes the presidency, although there are serious differences. Both countries are concerned about the growing maritime presence and influence of China. Indians are optimistic that the Biden administration will ease visa requirements for Indian immigration as well as its entry into the Nuclear Suppliers Group. Both countries hope to see increased trade. The U.S. is concerned about India's coziness with Russia on defense issues and its energy relationship with Iran despite U.S. sanctions. Vice President Kamala Harris expressed concern about the situation in Kashmir when she was a senator in 2019, and American concern about Indian treatment of dissenters and minorities is a sticky point, although it is unlikely to interfere with larger goals.

However US-Indian ties began to strain in April 2021 when India faced a massive spike in infections. The US had invoked the Defense Production Act of 1950 to ban the export of raw materials needed to produce vaccines in order to prioritize domestic vaccine production. According to The Times of India, also caused an explosion of anti-US and anti-western sentiment in India, as the U.S. had vaccine reserves and refused to share COVID-19 vaccine patents. This came after a plea by Adar Poonawalla, CEO of Serum Institute of India to lift the embargo on export of raw materials needed to ramp up production of COVID-19 vaccines, was rejected. But, in late April, right after a phone call with Ajit Doval, the National Security Advisor of India, the Biden administration stated it would make raw materials necessary for production of the Oxford–AstraZeneca COVID-19 vaccine available to India, and began to send more than $100 million USD (714 crore INR) worth of drug treatments, rapid diagnostic tests, ventilators, personal protective equipment, mechanical parts needed to manufacture vaccines to India, along with a team of public health experts from the United States Centers for Disease Control and Prevention. The US also stated that it planned to finance the expansion of Biological E. Limited, an Indian-based COVID-19 vaccine production company. India entered negotiations with the US after it declared that it would share 60 million Oxford–AstraZeneca vaccines with the world.

USS John Paul Jones intrusion
USS John Paul Jones

On April 7, 2021, The United States Navy guided missile destroyer USS John Paul Jones sailed through India's Exclusive Economic Zone, without New Delhi's prior consent, then publicly announced the event, causing a diplomatic spat. At a time when the United States and India had been deepening relations, such a move had raised eyebrows among the general public in both India and The United States. As per the official statement by the United States Navy's 7th Fleet, "On April 7, 2021 (local time) USS John Paul Jones (DDG 53) asserted navigational rights and freedoms approximately 130 nautical miles west of the Lakshadweep Islands, inside India’s exclusive economic zone, without requesting India’s prior consent, consistent with international law". India requires prior consent for military exercises or maneuvers in its exclusive economic zone or continental shelf, a claim inconsistent with international law. This freedom of navigation operation (“FONOP”) upheld the rights, freedoms, and lawful uses of the sea recognized in international law by challenging India’s excessive maritime claims. The Statement further added, "U.S. Forces operate in the Indo-Pacific region on a daily basis. All operations are designed in accordance with international law and demonstrate that the United States will fly, sail and operate wherever international law allows." The Pentagon, defended the 7th Fleet's statement by claiming that the event was consistent with international law.

The Indian Ministry of External Affairs released its statement after much media attention, the statement said, "The Government of India's stated position on the United Nations Convention on the Law of the Sea is that the Convention does not authorize other States to carry out in the Exclusive Economic Zone and on the continental shelf, military exercises or maneuvers, in particular those involving the use of weapons or explosives, without the consent of the coastal state", it further added, "The USS John Paul Jones was continuously monitored transiting from the Persian Gulf towards the Malacca Straits. We have conveyed our concerns regarding this passage through our EEZ to the Government of USA through diplomatic channels." Former Chief of Naval Staff of the Indian Navy, Admiral Arun Prakash commented on the event by tweeting "There is irony here. While India ratified UN Law of the Seas in 1995, the US has failed to do it so far. For the 7th Fleet to carry out FoN missions in Indian EEZ in violation of our domestic law is bad enough. But publicizing it? USN please switch on IFF!". He Further tweeted, "FoN ops by USN ships (ineffective as they may be) in South China Sea, are meant to convey a message to China that the putative EEZ around the artificial SCS islands is an “excessive maritime claim.” But what is the 7th Fleet message for India?"

State Visits by counterparts (2014 onwards)

Modi's visit to America, 2014

During the run-off to the 2014 Indian general election, there was wide-ranging scepticism regarding the future of the India–U.S. strategic relationship. Narendra Modi, whose US visa had been revoked while he was the Chief Minister of Gujarat, had been boycotted by US officials for almost a decade for his alleged role in the 2002 Gujarat riots. However, sensing Modi's inevitable victory well before the election, the US Ambassabor Nancy Powell had reached out to him. Moreover, following his 2014 election as the Prime Minister of India President Obama congratulated him over telephone and invited him to visit the US. US Secretary of State John Kerry visited New Delhi on 1 August to prepare the grounds for Modi's first ever US visit as Prime Minister. In September 2014, days before visiting the US in an interview to CNN's Fareed Zakaria, Modi said that "India and the United States are bound together, by history and culture" but acknowledged that there have been "ups and downs" in relations. Modi travelled to US from 27 to 30 September 2014, beginning with his maiden address in the United Nations general assembly followed by attending a gala public reception by the Indian American community in New York's Madison Square Garden before heading Washington, D.C. for the bilateral talk with Obama. While there, Modi also met several American business leaders and invited them to join his ambitious Make in India program in a bid to make India a manufacturing hub.

Obama's visit to India, 2015

President Barack Obama became the first US president to be the chief guest of the 66th Republic Day celebrations of India held on 26 January 2015. India and the US held their first ever bilateral dialogue on the UN and multilateral issues in the spirit of the "Delhi Declaration of Friendship" that strengthens and expands the two countries' relationship as part of the Post-2015 Development Agenda.

The conspicuous absence of major announcements, a key indicator of the state of US relations with the host country, led political commentators in both countries to highlight the confidence-building aspects of the visit.

Modi's visit to America, 2015

Prime Minister Narendra Modi toured the Silicon Valley and met with entrepreneurs – several of whom are persons of Indian origin – involved in successful microelectronics, digital communications and biotechnology start-ups to promote the NDA government's Make in India initiative. Modi left the U.S. West Coast and travelled to New York for the 2015 UN General Assembly meeting where he had bilateral discussions with US President Barack Obama.

Modi's visit to America, 2016
Prime Minister Narendra Modi meeting President Barack Obama in the Oval Office, at the White House, in Washington, DC, USA on June 07, 2016.

Prime Minister Narendra Modi while visiting the United States addressed a joint session of Congress highlighting the common traits of both democracies and long-term friendship between the two countries. In a speech lasting more than 45 minutes, Mr. Modi drew on parallels between the two countries and addressed a variety of issues where the two countries have worked together in the past and where the future course of action would lie.

Modi's visit to America, 2017

On June 26, 2017, Prime Minister Narendra Modi visited the United States and met US President Donald Trump. On 8 November 2017, the US announced a grant of nearly US$500,000 for organisations which came up with ideas and projects to promote religious freedom in India and Sri Lanka.

Modi's visit to America, 2019

In September 2019, Modi visited Houston and he addressed a large Indian American contingent in the Houston NRG stadium. Along with President Trump, he reaffirmed Indian American ties, with an emphasis on increased military cooperation with the initiation of the Tiger Triumph exercises.

Trump's visit to India, 2020

On February 24, 2020, Trump visited Ahmedabad, Gujarat to address a large Indian crowd. The event, titled "Namaste Trump", was a response to the "Howdy Modi" event held in 2019. Attendance of over 100,000 people was reported. The event served as a platform for the U.S. president and the Indian prime minister to show off their friendly relationship.

Trump also visited Agra, Uttar Pradesh and the Taj Mahal on the same day. In Agra, the Chief Minister of Uttar Pradesh, Yogi Adityanath welcomed the President and the First Lady. There were 3000 cultural artists showcasing art, cultural & music of various regions. However, political commentators state that Trump's first official visit to India had been overshadowed by the 2020 North East Delhi riots.

Modi's visit to America, 2021

Modi travelled to US from 22 to 25 September 2021, beginning with his maiden address in the United Nations general assembly before heading Washington, D.C. for the bilateral talk with President Joe Biden and Vice President Kamala Harris. While there, Modi also participated in the Quad Leaders' Summit.

The U.S. has four "foundational" agreements that it signs with its defence partners. The Pentagon describes the agreements as "routine instruments that the U.S. uses to promote military cooperation with partner-nations". American officials have stated that the agreements are not prerequisites for bilateral defence co-operation, but would make it simpler and more cost-effective to carry out activities such as refueling aircraft or ships in each other's countries and providing disaster relief. The first of the four agreements, the General Security Of Military Information Agreement (GSOMIA), was signed by India and the U.S. in 2002. The agreement enables the sharing of military intelligence between the two countries and requires each country to protect the others' classified information. The second agreement, the Logistics Exchange Memorandum of Agreement (LEMOA), was signed by the two countries on 29 August 2016. The LEMOA permits the military of either country to use the others' bases for re-supplying or carrying out repairs. The agreement does not make the provision of logistical support binding on either country, and requires individual clearance for each request. The third agreement, Communications Compatibility and Security Agreement (COMCASA) was signed during the inaugural 2+2 dialogue in September 2018. It is an India-specific variant of Communications and Information Security Memorandum of Agreement (CISMOA) that enables the two countries to share secure communication and exchange information on approved equipment during bilateral and multinational training exercises and operations. The fourth agreement, the Basic Exchange and Cooperation Agreement (BECA), signed in 2020, permits the exchange of unclassified and controlled unclassified geospatial products, topographical, nautical, and aeronautical data, products and services between India and the US National Geospatial-Intelligence Agency (NGA).

Harsh V. Pant, professor of International relations at King's College London, highlighted the importance of India to US strategic planning by saying: "India is key to the US' ability to create a stable balance of power in the larger Indo-Pacific and at a time of resource constraints, it needs partners like India to shore up its sagging credibility in the region in face of Chinese onslaught." Robert Boggs, professor of South Asia Studies at the Near East South Asia Center for Strategic Studies, opines that the US "overestimates both India's desire to improve the relationship and the benefits doing so would bring".

As part of America's policies to counter China, one of the Trump administration policies are to make India as one of the major defence partners for which it is in talks with Indian representatives to sell highly technologically advanced predator drones. India has floated a tender to buy 100 multi role fighter aircraft in the Indian MRCA competition (also called Mother of all defence deals), worth around US$15 billion under Narendra Modi's Make in India initiative. Although the deal is yet to be finalised in 2018, Present USA Trump's administration is now pushing for sales of advanced F-16 jet fighters, and F/A-18 Super Hornet

In a meeting between President George W. Bush and Prime Minister Atal Bihari Vajpayee in November 2001, the two leaders expressed a strong interest in transforming the US-India bilateral relationship. High-level meetings and concrete cooperation between the two countries increased during 2002 and 2003. In January 2004, the US and India launched the "Next Steps in Strategic Partnership" (NSSP), which was both a milestone in the transformation of the bilateral relationship and a blueprint for its further progress.

In July 2005, Bush hosted Prime Minister Manmohan Singh in Washington, D.C. The two leaders announced the successful completion of the NSSP, as well as other agreements which further enhanced cooperation in the areas of civil nuclear, civil space, and high-technology commerce. Other initiatives announced included a US-India economic dialogue, the fight Against HIV/AIDS, disaster relief, technology cooperation, an agriculture knowledge initiative, a trade policy forum, energy dialogue, CEO Forum, and an initiative to assist each other in furthering democracy and freedom. President Bush made a reciprocal visit to India in March 2006, during which the progress of these initiatives were reviewed, and new initiatives were launched.

In June 2015, US defence secretary Ashton Carter visited India and became the first American defence secretary to visit an Indian military command. In December of the same year, Manohar Parrikar became the first Indian defence minister to visit the US Pacific Command.

In March 2016, India rejected a proposal by the US to join naval patrols in the South China Sea alongside Japan and Australia. Defense Minister Manohar Parrikar said: "India has never taken part in any joint patrol; we only do joint exercises. The question of joint patrol does not arise."

In January 2017, Peter Lavoy, Senior Director for South Asian Affairs at the U.S. National Security Council, declared that the partnership between India and the United States under Barack Obama's administration had been "incredibly successful". Lavoy stated, "I can tell you quite definitively that due to our partnerships, several terrorism plots were foiled. Indian lives and American lives were saved because of this partnership."

On 27 October 2020, the United States and India signed the Basic Exchange and Cooperation Agreement (BECA), enabling greater information-sharing and further defense cooperation, to counter China's growing military power in the region.

Nuclear Cooperation

Pokhran Tests

In 1998, India tested nuclear weapons which resulted in several US, Japanese and European sanctions on India. India's then defence minister, George Fernandes, said that India's nuclear programme was necessary as it provided a deterrence to some potential nuclear threat. Most of the sanctions imposed on India were removed by 2001. India has categorically stated that it will never use weapons first but will defend if attacked.

The economic sanctions imposed by the United States in response to India's nuclear tests in May 1998 appeared, at least initially, to seriously damage India-US relations. President Bill Clinton imposed wide-ranging sanctions pursuant to the 1994 Nuclear Proliferation Prevention Act. US sanctions on Indian entities involved in the nuclear industry and opposition to international financial institution loans for non-humanitarian assistance projects in India. The United States encouraged India to sign the Comprehensive Nuclear-Test-Ban Treaty (CTBT) immediately and without condition. The United States also called for restraint in missile and nuclear testing and deployment by both India and Pakistan. The non-proliferation dialogue initiated after the 1998 nuclear tests has bridged many of the gaps in understanding between the countries.

Easing of Tension

In late September 2001, President Bush lifted sanctions imposed under the terms of the 1994 Nuclear Proliferation Prevention Act following India's nuclear tests in May 1998. A succession of non-proliferation dialogues bridged many of the gaps in understanding between the countries.

In December 2006, the US Congress passed the historic India–United States Civilian Nuclear Agreement|Henry J. Hyde US–India Peaceful Atomic Cooperation Act, which allows direct civilian nuclear commerce with India for the first time in 30 years. US policy had been opposed to nuclear cooperation with India in prior years because India had developed nuclear weapons against international conventions, and had never signed the Nuclear Non-Proliferation Treaty (NNPT). The legislation clears the way for India to buy US nuclear reactors and fuel for civilian use.

The India–United States Civil Nuclear Agreement also referred to as the "123 Agreement", signed on 10 October 2008 is a bilateral agreement for peaceful nuclear cooperation which governs civil nuclear trade between American and Indian firms to participate in each other's civil nuclear energy sector. For the agreement to be operational, nuclear vendors and operators must comply with India's 2010 Nuclear Liability Act which stipulates that nuclear suppliers, contractors and operators must bear financial responsibility in case of an accident.

Prominent industrial accidents (1984 Bhopal chemical-gas disaster and the 2011 Fukushima nuclear disaster) have led to greater scrutiny by civil society into corporate responsibility and financial liability obligations of vendors and operators of critical infrastructure. In 2010, the Indian Parliament voted to pass the Civil Liability for Nuclear Damage Act to address concerns and provide civil liability for nuclear damage and prompt compensation to the victims of a nuclear incident.

On 27 March 2019, India and the US signed an agreement to "strengthen bilateral security and civil nuclear cooperation" including the construction of six American nuclear reactors in India.

Post–September 11

India's contribution to the War on Terror has helped India's diplomatic relations with several countries. Over the past few years, India has held numerous joint military exercises with United States and European nations that have resulted in a strengthened US-India and EU-India bilateral relationship. India's bilateral trade with Europe and US has more than doubled in the last five years.

However, India has not signed the CTBT, or the Nuclear Non-Proliferation Treaty, claiming the discriminatory nature of the treaty that allows the five declared nuclear countries of the world to keep their nuclear arsenal and develop it using computer simulation testing. Prior to its nuclear testing, India had pressed for a comprehensive destruction of nuclear weapons by all countries of the world in a time-bound frame. This was not favoured by the United States and by certain other countries. Presently, India has declared its policy of "no-first use of nuclear weapons" and the maintenance of a "credible nuclear deterrence". The USA, under President George W. Bush has also lifted most of its sanctions on India and has resumed military co-operation. Relations with USA have considerably improved in the recent years, with the two countries taking part in joint naval exercises off the coast of India and joint air exercises both in India as well as in the United States.

India has been pushing for reforms in the United Nations and in the World Trade Organization with mixed results. India's candidature for a permanent seat at the UN Security Council is currently backed by several countries including Russia, United Kingdom, France, Germany, Japan, Brazil, African Union nations and United States. In 2005, the United States signed a nuclear co-operation agreement with India even though the latter is not a part of the Nuclear Non-Proliferation Treaty. The United States agreed that India's strong nuclear non-proliferation record made it an exception and persuaded other Nuclear Suppliers Group members to sign similar deals with India.

On 2 March 2006 India and the United States signed the Indo-US Nuclear Pact on co-operation in civilian nuclear field. This was signed during the four days state visit of USA President George Bush in India. On its part, India would separate its civilian and military nuclear programmes, and the civilian programmes would be brought under the safeguards of International Atomic Energy Agency (IAEA). The United States would sell India the reactor technologies and the nuclear fuel for setting up and upgrading its civilian nuclear programme. The US Congress needs to ratify this pact since US federal law prohibits the trading of nuclear technologies and materials outside the framework of the Nuclear Suppliers Group (NSG).

Economic relations

The United States is one of India's largest direct investors. From 1991 to 2004, the stock of FDI inflow has increased from US$11 million to $344.4 million, and totaling $4.13 billion. This is a compound rate increase of 57.5 percent annually. Indian direct investments abroad began in 1992, and Indian corporations and registered partnership firms now can and do invest in businesses up to 100 percent of their net worth. India's largest outgoing investments are in the manufacturing sector, which accounts for 54.8 percent of the country's foreign investments. The second largest are in non-financial services (software development), accounting for 35.4 percent of investments.

On 3 August 2018, India became the third Asian nation to be granted Strategic Trade Authorization-1 (STA-1) status by the United States. STA-1 enables the export of high-technology products in civil space and defence from the US to India.

Trade relations

The US is India's second largest trading partner, and India is its 9th largest trading partner. In 2017, the US exported $25.7 billion worth of goods to India, and imported $48.6 billion worth of Indian goods. Major items imported from India include information technology services, textiles, machinery, gems and diamonds, chemicals, iron and steel products, coffee, tea, and other edible food products. Major American items imported by India include aircraft, fertilisers, computer hardware, scrap metal, and medical equipment.

The United States is also India's largest investment partner, with a direct investment of $10 billion (accounting for 9 percent of total foreign investment). Americans have made notable foreign investments in the Asian country's power generation, telecommunications, ports, roads, petroleum exploration and processing, and mining industries.

American imports from India amounted to $46.6 billion or 2% of its overall imports, and 15.3% of India's overall exports in 2015. The 10 major commodities exported from India to the US were:

  1. Gems, precious metals and coins ($9.5 billion)
  2. Pharmaceuticals ($6.1 billion)
  3. Oil ($2.8 billion)
  4. Machinery: $2.5 billion
  5. Other textiles, worn clothing: $2.5 billion
  6. Clothing (not knit or crochet): $2.2 billion
  7. Organic chemicals: $2.1 billion
  8. Knit or crochet clothing: $1.7 billion
  9. Vehicles: $1.4 billion
  10. Iron or steel products: $1.3 billion

American exports to India amounted to $20.5 billion or 5.2% of India's overall imports in 2015. The 10 major commodities exported from the US to India were:

  1. Gems, precious metals and coins ($3.4 billion)
  2. Machinery: $3 billion
  3. Electronic equipment: $1.6 billion
  4. Medical, technical equipment: $1.4 billion
  5. Oil: $1.3 billion

  8. Organic chemicals: $799.4 million
  9. Other chemical goods: $769.1 million
  10. Fruits, nuts: $684.7 million

In July 2005, President Bush and Prime Minister Manmohan Singh created a new programme called the Trade Policy Forum. It is run by a representative from each nation. The United States Trade Representative was Rob Portman, and the Indian Commerce Secretary then-Minister of Commerce Kamal Nath. The goal of the programme is to increase bilateral trade and investment flow. There are five main sub-divisions of the Trade Policy Forum, including:

  • The Agricultural Trade group has three main objectives: agreeing on terms that will allow India to export mangoes to the United States, permitting India's Agricultural and Process Food Products Export Development Authority (APEDA) to certify Indian products to the standards of the U.S. Department of Agriculture, and executing regulation procedures for approving edible wax on fruit.
  • The goals of the Tariff and Non-Tariff Barriers group include agreeing that insecticides manufactured by US companies can be sold throughout India. India had also agreed to cut special regulations on trading carbonated drinks, many medicinal drugs, and lowering regulations on many imports that are not of an agricultural nature. Both nations have agreed to discuss improved facets of Indian regulation in the trade of jewellery, computer parts, motorcycles, fertiliser, and those tariffs that affect American exporting of boric acid. The group has also discussed matters such as those wishing to break into the accounting market, Indian companies gaining licenses for the telecommunications industry, and setting policies regarding Indian media and broadcasting markets. Other foci include the exchange of valuable information on recognizing different professional services, discussing the movement and positioning of people in developing industries, continuation of talks on financial services markets, limitation of equities, insurance, retail, joint investment in agricultural processing and transportation industries, and small business initiatives.
  • India and the US will sign the Basic Exchange and Cooperation Agreement (BECA), the last of four so-called foundational agreements for sharing sensitive information and sales of advanced military hardware, during the 2+2 ministerial dialogue on 27 October 2020.

India-US strategic partnership

Prime Minister Narendra Modi with President Barack Obama at the White House.

India-US relations got strategic content in the early 1960s. The rise of the People's Republic of China worried the policymakers in Washington. Chinese assertion in Tibet, its role in the Korean War and other such acts concerned Washington. As the relations between India and China were heated during the late fifties, the Americans found a golden opportunity to take advantage of this situation to promote India as a counterweight to China. But any unidimensional alliance is bound to be short-lived and this alliance was no exception to this general rule. As China ceased to be a headache for the American policymakers by the late sixties, this unidimensional alliance disappeared into thin air.

After the end of the Cold War, Indian and American interests converged in a number of areas, including counter-terrorism, promotion of democracy, counter-proliferation, freedom of navigation in the Indian Ocean, and the balance of power in Asia.

As the world's oldest and largest democracies, respectively, the U.S. and India share historic ties. India is a founding member of the "Community of Democracies"—a prominent endeavour of the United States on promotion of democracy. However, the India rejected the suggestion of the USA about setting up a Centre for Asian Democracy.

Indian Prime Minister Manmohan Singh was the guest of honour at the first state dinner, which took place on 24 November 2009, of the administration of US President Barack Obama. Obama later visited India from 6–9 November 2010, signing numerous trade and defence agreements with India. He addressed the joint session of the Indian parliament in New Delhi, becoming only the second US president to do so, and announced that the United States would lend its support to India's bid for a permanent seat in the United Nations Security Council, signifying the growing strategic dimension of the relationship between the world's two largest democracies.

On 27 October 2020, US-India signed a military agreement on sharing sensitive satellite data. The Basic Exchange and Cooperation Agreement, or BECA, allows US's strategic partners to access a range of sensitive geospatial and aeronautical data which is useful for military actions.

In December 2020, US India Business Council president Nisha Desai Biswal claimed that the ties between the two nations will continue and grow stronger in 2021, as the Biden administration will prioritize their trade deals for a prospering economic relationship.

Tensions over Russian relations

The purchase of S-400 missile system by India, resulted in an imbroglio in the US Congress. Previously, the Trump administration admonished India that it might entice economic sanctions by the United States. But since India looms as a counterweight to China, the significance of India is creeping upon the US Senate. Following that, two major Senators John Cornyn from the Republican Party and Mark Warner from the Democratic Party urged president Joe Biden to waive sanctions against New Delhi as it might euthanize the cumulative cooperation with India to maintain the hegemony of the United States of America across the region of South Asia & the Indian Ocean region.

Following the 2022 Russian invasion of Ukraine, India abstained on a United Nations resolution condemning the invasion, saying it was "deeply disturbed" by Russia's invasion. In a meeting of the Quadrilateral Security Dialogue on the implications of the crisis for the region, President Biden noted India's abstention, saying that most global allies were united against Russia. Speaking to the US Senate Foreign Relations Committee, US diplomat Donald Lu said the Biden administration was still considering sanctions against India over its S-400 deal with Russia, and its abstention at the UN.
