Groupthink

From Wikipedia, the free encyclopedia

Groupthink is a psychological phenomenon that occurs within a group of people in which the desire for harmony or conformity in the group results in an irrational or dysfunctional decision-making outcome. Cohesiveness, or the desire for cohesiveness, in a group may produce a tendency among its members to agree at all costs. This causes the group to minimize conflict and reach a consensus decision without critical evaluation.

Groupthink is a construct of social psychology, but has an extensive reach and influences literature in the fields of communication studies, political science, management, and organizational theory, as well as important aspects of deviant religious cult behaviour.

Groupthink is sometimes stated to occur (more broadly) within natural groups within the community, for example to explain the lifelong different mindsets of those with differing political views (such as "conservatism" and "liberalism" in the U.S. political context  or the purported benefits of team work vs. work conducted in solitude). However, this conformity of viewpoints within a group does not mainly involve deliberate group decision-making, and might be better explained by the collective confirmation bias of the individual members of the group.

The term was coined in 1952 by William H. Whyte Jr.. Most of the initial research on groupthink was conducted by Irving Janis, a research psychologist from Yale University. Janis published an influential book in 1972, which was revised in 1982. Janis used the Bay of Pigs disaster (the failed invasion of Castro's Cuba in 1961) and the Japanese attack on Pearl Harbor in 1941 as his two prime case studies. Later studies have evaluated and reformulated his groupthink model.

Groupthink requires individuals to avoid raising controversial issues or alternative solutions, and there is loss of individual creativity, uniqueness and independent thinking. The dysfunctional group dynamics of the "ingroup" produces an "illusion of invulnerability" (an inflated certainty that the right decision has been made). Thus the "ingroup" significantly overrates its own abilities in decision-making and significantly underrates the abilities of its opponents (the "outgroup"). Furthermore, groupthink can produce dehumanizing actions against the "outgroup". Members of a group can often feel peer pressure to "go along with the crowd" in fear of rocking the boat or of what them speaking up will do to the overall to how their teammates perceive them. Group interactions tend to favor clear and harmonious agreements and it can be a cause for concern when little to no new innovations or arguments for better policies, outcomes and structures are called to question. (McLeod). Groupthink can often be referred to as a group of “yes men” because group activities and group projects in general make it extremely easy to pass on not offering constructive opinions.

Some methods that have been used to counteract group think in the past is selecting teams from more diverse backgrounds, and even mixing men and women for groups (Kamalnath). Groupthink can be considered by many to be a detriment to companies, organizations and in any work situations. Most positions that are senior level need individuals to be independent in their thinking. There is a positive correlation found between outstanding executives and decisiveness (Kelman). Groupthink also prohibits an organization from moving forward and innovating if no one ever speaks up and says something could be done differently.

Antecedent factors such as group cohesiveness, faulty group structure, and situational context (e.g., community panic) play into the likelihood of whether or not groupthink will impact the decision-making process.

History

From "Groupthink" by William H. Whyte Jr. in Fortune magazine, March 1952

William H. Whyte Jr. derived the term from George Orwell's Nineteen Eighty-Four, and popularized it in 1952 in Fortune magazine:

Groupthink being a coinage – and, admittedly, a loaded one – a working definition is in order. We are not talking about mere instinctive conformity – it is, after all, a perennial failing of mankind. What we are talking about is a rationalized conformity – an open, articulate philosophy which holds that group values are not only expedient but right and good as well.

Irving Janis pioneered the initial research on the groupthink theory. He does not cite Whyte, but coined the term again by analogy with "doublethink" and similar terms that were part of the newspeak vocabulary in the novel Nineteen Eighty-Four by George Orwell. He initially defined groupthink as follows:

I use the term groupthink as a quick and easy way to refer to the mode of thinking that persons engage in when concurrence-seeking becomes so dominant in a cohesive ingroup that it tends to override realistic appraisal of alternative courses of action. Groupthink is a term of the same order as the words in the newspeak vocabulary George Orwell used in his dismaying world of 1984. In that context, groupthink takes on an invidious connotation. Exactly such a connotation is intended, since the term refers to a deterioration in mental efficiency, reality testing and moral judgments as a result of group pressures.

He went on to write:

The main principle of groupthink, which I offer in the spirit of Parkinson's Law, is this: "The more amiability and esprit de corps there is among the members of a policy-making ingroup, the greater the danger that independent critical thinking will be replaced by groupthink, which is likely to result in irrational and dehumanizing actions directed against outgroups".

Janis set the foundation for the study of groupthink starting with his research in the American Soldier Project where he studied the effect of extreme stress on group cohesiveness. After this study he remained interested in the ways in which people make decisions under external threats. This interest led Janis to study a number of "disasters" in American foreign policy, such as failure to anticipate the Japanese attack on Pearl Harbor (1941); the Bay of Pigs Invasion fiasco (1961); and the prosecution of the Vietnam War (1964–67) by President Lyndon Johnson. He concluded that in each of these cases, the decisions occurred largely because of groupthink, which prevented contradictory views from being expressed and subsequently evaluated.

After the publication of Janis' book Victims of Groupthink in 1972, and a revised edition with the title Groupthink: Psychological Studies of Policy Decisions and Fiascoes in 1982, the concept of groupthink was used to explain many other faulty decisions in history. These events included Nazi Germany's decision to invade the Soviet Union in 1941, the Watergate scandal and others. Despite the popularity of the concept of groupthink, fewer than two dozen studies addressed the phenomenon itself following the publication of Victims of Groupthink, between the years 1972 and 1998. This was surprising considering how many fields of interests it spans, which include political science, communications, organizational studies, social psychology, management, strategy, counseling, and marketing. One can most likely explain this lack of follow-up in that group research is difficult to conduct, groupthink has many independent and dependent variables, and it is unclear "how to translate [groupthink's] theoretical concepts into observable and quantitative constructs".

Nevertheless, outside research psychology and sociology, wider culture has come to detect groupthink in observable situations, for example:

  • " [...] critics of Twitter point to the predominance of the hive mind in such social media, the kind of groupthink that submerges independent thinking in favor of conformity to the group, the collective"
  • "[...] leaders often have beliefs which are very far from matching reality and which can become more extreme as they are encouraged by their followers. The predilection of many cult leaders for abstract, ambiguous, and therefore unchallengeable ideas can further reduce the likelihood of reality testing, while the intense milieu control exerted by cults over their members means that most of the reality available for testing is supplied by the group environment. This is seen in the phenomenon of 'groupthink', alleged to have occurred, notoriously, during the Bay of Pigs fiasco."
  • "Groupthink by Compulsion [...] [G]roupthink at least implies voluntarism. When this fails, the organization is not above outright intimidation. [...] In [a nationwide telecommunications company], refusal by the new hires to cheer on command incurred consequences not unlike the indoctrination and brainwashing techniques associated with a Soviet-era gulag."

Symptoms

To make groupthink testable, Irving Janis devised eight symptoms indicative of groupthink:

Type I: Overestimations of the group — its power and morality

  • Illusions of invulnerability creating excessive optimism and encouraging risk taking.
  • Unquestioned belief in the morality of the group, causing members to ignore the consequences of their actions.

Type II: Closed-mindedness

  • Rationalizing warnings that might challenge the group's assumptions.
  • Stereotyping those who are opposed to the group as weak, evil, biased, spiteful, impotent, or stupid.

Type III: Pressures toward uniformity

  • Self-censorship of ideas that deviate from the apparent group consensus.
  • Illusions of unanimity among group members, silence is viewed as agreement.
  • Direct pressure to conform placed on any member who questions the group, couched in terms of "disloyalty"
  • Mindguards— self-appointed members who shield the group from dissenting information.

Causes

Janis prescribed three antecedent conditions to groupthink.

  • High group cohesiveness. Janis emphasized that cohesiveness is the main factor that leads to groupthink. Groups that lack cohesiveness can of course make bad decisions, but they do not experience groupthink. In a cohesive group, members avoid speaking out against decisions, avoid arguing with others, and work towards maintaining friendly relationships in the group. If cohesiveness gets to such a high level where there are no longer disagreements between members, then the group is ripe for groupthink.
    • deindividuation: group cohesiveness becomes more important than individual freedom of expression
  • Structural faults. Cohesion is necessary for groupthink, but it becomes even more likely when the group is organized in ways that disrupt the communication of information, and when the group engages in carelessness while making decisions.
    • insulation of the group: can promote the development of unique, inaccurate perspectives on issues the group is dealing with, and can then lead to faulty solutions to the problem.
    • lack of impartial leadership: leaders can completely control the group discussion, by planning what will be discussed, only allowing certain questions to be asked, and asking for opinions of only certain people in the group. Closed style leadership is when leaders announce their opinions on the issue before the group discusses the issue together. Open style leadership is when leaders withhold their opinion until a later time in the discussion. Groups with a closed style leader have been found to be more biased in their judgments, especially when members had a high degree for certainty.
    • lack of norms requiring methodological procedures
    • homogeneity of members' social backgrounds and ideology
  • Situational context:
    • highly stressful external threats: High stake decisions can create tension and anxiety, and group members then may cope with the decisional stress in irrational ways. Group members may rationalize their decision by exaggerating the positive consequences and minimizing the possible negative consequences. In attempt to minimize the stressful situation, the group will make a quick decision with little to no discussion or disagreement about the decision. Studies have shown that groups under high stress are more likely to make errors, lose focus of the ultimate goal, and use procedures that members know have not been effective in the past.
    • recent failures: can lead to low self-esteem, resulting in agreement with the group for fear of being seen as wrong
    • excessive difficulties in decision-making tasks
    • time pressures: group members are more concerned with efficiency and quick results, instead of quality and accuracy. Additionally, time pressures can lead to group members overlooking important information regarding the issue of discussion.
    • moral dilemmas

Although it is possible for a situation to contain all three of these factors, all three are not always present even when groupthink is occurring. Janis considered a high degree of cohesiveness to be the most important antecedent to producing groupthink and always present when groupthink was occurring; however, he believed high cohesiveness would not always produce groupthink. A very cohesive group abides to all group norms; whether or not groupthink arises is dependent on what the group norms are. If the group encourages individual dissent and alternative strategies to problem solving, it is likely that groupthink will be avoided even in a highly cohesive group. This means that high cohesion will lead to groupthink only if one or both of the other antecedents is present, situational context being slightly more likely than structural faults to produce groupthink.

Prevention

As observed by Aldag and Fuller (1993), the groupthink phenomenon seems to rest on a set of unstated and generally restrictive assumptions:

  • The purpose of group problem solving is mainly to improve decision quality
  • Group problem solving is considered a rational process.
  • Benefits of group problem solving:
    • variety of perspectives
    • more information about possible alternatives
    • better decision reliability
    • dampening of biases
    • social presence effects
  • Groupthink prevents these benefits due to structural faults and provocative situational context
  • Groupthink prevention methods will produce better decisions
  • An illusion of well-being is presumed to be inherently dysfunctional.
  • Group pressures towards consensus lead to concurrence-seeking tendencies.

It has been thought that groups with the strong ability to work together will be able to solve dilemmas in a quicker and more efficient fashion than an individual. Groups have a greater amount of resources which lead them to be able to store and retrieve information more readily and come up with more alternative solutions to a problem. There was a recognized downside to group problem solving in that it takes groups more time to come to a decision and requires that people make compromises with each other. However, it was not until the research of Janis appeared that anyone really considered that a highly cohesive group could impair the group's ability to generate quality decisions. Tight-knit groups may appear to make decisions better because they can come to a consensus quickly and at a low energy cost; however, over time this process of decision-making may decrease the members' ability to think critically. It is, therefore, considered by many to be important to combat the effects of groupthink.

According to Janis, decision-making groups are not necessarily destined to groupthink. He devised ways of preventing groupthink:

  • Leaders should assign each member the role of "critical evaluator". This allows each member to freely air objections and doubts.
  • Leaders should not express an opinion when assigning a task to a group.
  • Leaders should absent themselves from many of the group meetings to avoid excessively influencing the outcome.
  • The organization should set up several independent groups, working on the same problem.
  • All effective alternatives should be examined.
  • Each member should discuss the group's ideas with trusted people outside of the group.
  • The group should invite outside experts into meetings. Group members should be allowed to discuss with and question the outside experts.
  • At least one group member should be assigned the role of devil's advocate. This should be a different person for each meeting.

The devil's advocate in a group may provide questions and insight which contradict the majority group in order to avoid groupthink decisions. A study by Hartwig insists that the devil's advocacy technique is very useful for group problem-solving. It allows for conflict to be used in a way that is most-effective for finding the best solution so that members will not have to go back and find a different solution if the first one fails. Hartwig also suggests that the devil's advocacy technique be incorporated with other group decision-making models such as the functional theory to find and evaluate alternative solutions. The main idea of the devil's advocacy technique is that somewhat structured conflict can be facilitated to not only reduce groupthink, but to also solve problems.

A similar term to groupthink is the Abilene paradox, another phenomenon that is detrimental when working in groups. When organizations fall into the Abilene paradox, they take actions in contradiction to what their perceived goals may be and therefore defeat the very purposes they are trying to achieve. Failure to communicate desires or beliefs can cause the Abilene paradox.

As explained in the Abilene paradox, the Watergate scandal is an example of this. Before the scandal had occurred, a meeting took place where they discussed the issue. One of Nixon's campaign aides was unsure if he should speak up and give his input. If he had voiced his disagreement with the group's decision, it is possible that the scandal could have been avoided.

Other examples of how groupthink could be avoided or prevented:

After the Bay of Pigs invasion fiasco, President John F. Kennedy sought to avoid groupthink during the Cuban Missile Crisis using "vigilant appraisal". During meetings, he invited outside experts to share their viewpoints, and allowed group members to question them carefully. He also encouraged group members to discuss possible solutions with trusted members within their separate departments, and he even divided the group up into various sub-groups, to partially break the group cohesion. Kennedy was deliberately absent from the meetings, so as to avoid pressing his own opinion.

Cass Sunstein reports that introverts can sometimes be silent in meetings with extroverts; he recommends explicitly asking for each person's opinion, either during the meeting or afterwards in one-on-one sessions. Sunstein points to studies showing groups with a high level of internal socialization and happy talk are more prone to bad investment decisions due to groupthink, compared with groups of investors who are relative strangers and more willing to be argumentative. To avoid group polarization, where discussion with like-minded people drives an outcome further to an extreme than any of the individuals favored before the discussion, he recommends creating heterogeneous groups which contain people with different points of view. Sunstein also points out that people arguing a side they do not sincerely believe (in the role of devil's advocate) tend to be much less effective than a sincere argument. This can be accomplished by dissenting individuals, or a group like a Red Team that is expected to pursue an alternative strategy or goal "for real".

Empirical findings and meta-analysis

Testing groupthink in a laboratory is difficult because synthetic settings remove groups from real social situations, which ultimately changes the variables conducive or inhibitive to groupthink. Because of its subjective nature, researchers have struggled to measure groupthink as a complete phenomenon, instead frequently opting to measure its particular factors. These factors range from causal to effectual and focus on group and situational aspects.

Park (1990) found that "only 16 empirical studies have been published on groupthink", and concluded that they "resulted in only partial support of his [Janis's] hypotheses". Park concludes, "despite Janis' claim that group cohesiveness is the major necessary antecedent factor, no research has shown a significant main effect of cohesiveness on groupthink." Park also concludes that research on the interaction between group cohesiveness and leadership style does not support Janis' claim that cohesion and leadership style interact to produce groupthink symptoms. Park presents a summary of the results of the studies analyzed. According to Park, a study by Huseman and Drive (1979) indicates groupthink occurs in both small and large decision-making groups within businesses. This results partly from group isolation within the business. Manz and Sims (1982) conducted a study showing that autonomous work groups are susceptible to groupthink symptoms in the same manner as decisions making groups within businesses. Fodor and Smith (1982) produced a study revealing that group leaders with high power motivation create atmospheres more susceptible to groupthink. Leaders with high power motivation possess characteristics similar to leaders with a "closed" leadership style—an unwillingness to respect dissenting opinion. The same study indicates that level of group cohesiveness is insignificant in predicting groupthink occurrence. Park summarizes a study performed by Callaway, Marriott, and Esser (1985) in which groups with highly dominant members "made higher quality decisions, exhibited lowered state of anxiety, took more time to reach a decision, and made more statements of disagreement/agreement". Overall, groups with highly dominant members expressed characteristics inhibitory to groupthink. If highly dominant members are considered equivalent to leaders with high power motivation, the results of Callaway, Marriott, and Esser contradict the results of Fodor and Smith. A study by Leana (1985) indicates the interaction between level of group cohesion and leadership style is completely insignificant in predicting groupthink. This finding refutes Janis' claim that the factors of cohesion and leadership style interact to produce groupthink. Park summarizes a study by McCauley (1989) in which structural conditions of the group were found to predict groupthink while situational conditions did not. The structural conditions included group insulation, group homogeneity, and promotional leadership. The situational conditions included group cohesion. These findings refute Janis' claim about group cohesiveness predicting groupthink.

Overall, studies on groupthink have largely focused on the factors (antecedents) that predict groupthink. Groupthink occurrence is often measured by number of ideas/solutions generated within a group, but there is no uniform, concrete standard by which researchers can objectively conclude groupthink occurs. The studies of groupthink and groupthink antecedents reveal a mixed body of results. Some studies indicate group cohesion and leadership style to be powerfully predictive of groupthink, while other studies indicate the insignificance of these factors. Group homogeneity and group insulation are generally supported as factors predictive of groupthink.

Case studies

Politics and military

Groupthink can have a strong hold on political decisions and military operations, which may result in enormous wastage of human and material resources. Highly qualified and experienced politicians and military commanders sometimes make very poor decisions when in a suboptimal group setting. Scholars such as Janis and Raven attribute political and military fiascoes, such as the Bay of Pigs Invasion, the Vietnam War, and the Watergate scandal, to the effect of groupthink. More recently, Dina Badie argued that groupthink was largely responsible for the shift in the U.S. administration's view on Saddam Hussein that eventually led to the 2003 invasion of Iraq by the United States. After the September 11 attacks, "stress, promotional leadership, and intergroup conflict" were all factors that gave rise to the occurrence of groupthink. Political case studies of groupthink serve to illustrate the impact that the occurrence of groupthink can have in today's political scene.

Bay of Pigs invasion and the Cuban Missile Crisis

The United States Bay of Pigs Invasion of April 1961 was the primary case study that Janis used to formulate his theory of groupthink. The invasion plan was initiated by the Eisenhower administration, but when the Kennedy administration took over, it "uncritically accepted" the plan of the Central Intelligence Agency (CIA). When some people, such as Arthur M. Schlesinger Jr. and Senator J. William Fulbright, attempted to present their objections to the plan, the Kennedy team as a whole ignored these objections and kept believing in the morality of their plan. Eventually Schlesinger minimized his own doubts, performing self-censorship. The Kennedy team stereotyped Fidel Castro and the Cubans by failing to question the CIA about its many false assumptions, including the ineffectiveness of Castro's air force, the weakness of Castro's army, and the inability of Castro to quell internal uprisings.

Janis argued the fiasco that ensued could have been prevented if the Kennedy administration had followed the methods to preventing groupthink adopted during the Cuban Missile Crisis, which took place just one year later in October 1962. In the latter crisis, essentially the same political leaders were involved in decision-making, but this time they learned from their previous mistake of seriously under-rating their opponents.

Pearl Harbor

The attack on Pearl Harbor on December 7, 1941, is a prime example of groupthink. A number of factors such as shared illusions and rationalizations contributed to the lack of precaution taken by U.S. Navy officers based in Hawaii. The United States had intercepted Japanese messages and they discovered that Japan was arming itself for an offensive attack somewhere in the Pacific Ocean. Washington took action by warning officers stationed at Pearl Harbor, but their warning was not taken seriously. They assumed that the Empire of Japan was taking measures in the event that their embassies and consulates in enemy territories were usurped.

The U.S. Navy and Army in Pearl Harbor also shared rationalizations about why an attack was unlikely. Some of them included:

  • "The Japanese would never dare attempt a full-scale surprise assault against Hawaii because they would realize that it would precipitate an all-out war, which the United States would surely win."
  • "The Pacific Fleet concentrated at Pearl Harbor was a major deterrent against air or naval attack."
  • "Even if the Japanese were foolhardy to send their carriers to attack us [the United States], we could certainly detect and destroy them in plenty of time."
  • "No warships anchored in the shallow water of Pearl Harbor could ever be sunk by torpedo bombs launched from enemy aircraft."

Space Shuttle Challenger disaster

On January 28, 1986, the US launched the Space Shuttle Challenger. This was to be monumental for NASA, as a high school teacher was among the crew and was to be the first American civilian in space. NASA's engineering and launch teams rely on group work, and in order to launch the shuttle the team members must affirm each system is functioning nominally. The Thiokol engineers who designed and built the Challenger's rocket boosters warned that the temperature for the day of the launch could result in total failure of the vehicles and deaths of the crew. The launch resulted in disaster and grounded space shuttle flights for nearly three years.

The Challenger case was subject to a more quantitatively oriented test of Janis's groupthink model performed by Esser and Lindoerfer, who found clear signs of positive antecedents to groupthink in the critical decisions concerning the launch of the shuttle. The day of the launch was rushed for publicity reasons. NASA wanted to captivate and hold the attention of America. Having civilian teacher Christa McAuliffe on board to broadcast a live lesson, and the possible mention by president Ronald Reagan in the State of the Union address, were opportunities NASA deemed critical to increasing interest in its potential civilian space flight program. The schedule NASA set out to meet was, however, self-imposed. It seemed incredible to many that an organization with a perceived history of successful management would have locked itself into a schedule it had no chance of meeting.

2016 United States presidential election

In the weeks and months preceding the 2016 United States presidential election, there was near-unanimity among news media outlets and polling organizations that Hillary Clinton's election was extremely likely. For example, on November 7, the day before the election, The New York Times opined that Clinton then had "a consistent and clear advantage in states worth at least 270 electoral votes". The Times estimated the probability of a Clinton win at 84%. Also on November 7, Reuters estimated the probability of Clinton defeating Donald Trump in the election at 90%, and The Huffington Post put Clinton's odds of winning at 98.2% based on "9.8 million simulations".

The disconnect between the election results and the pre-election estimates, both from news media outlets and from pollsters, may have been due to three factors: news and polling professionals couldn't imagine a candidate as unconventional as Trump becoming president; Trump supporters may have been under-sampled by surveys or may have lied to or misled pollsters out of fear of social ostracism; and polls may have been unable to account for Russian interference in the 2016 United States elections.

Corporate world

In the corporate world, ineffective and suboptimal group decision-making can negatively affect the health of a company and cause a considerable amount of monetary loss.

Swissair

Aaron Hermann and Hussain Rammal illustrate the detrimental role of groupthink in the collapse of Swissair, a Swiss airline company that was thought to be so financially stable that it earned the title the "Flying Bank". The authors argue that, among other factors, Swissair carried two symptoms of groupthink: the belief that the group is invulnerable and the belief in the morality of the group. In addition, before the fiasco, the size of the company board was reduced, subsequently eliminating industrial expertise. This may have further increased the likelihood of groupthink. With the board members lacking expertise in the field and having somewhat similar background, norms, and values, the pressure to conform may have become more prominent. This phenomenon is called group homogeneity, which is an antecedent to groupthink. Together, these conditions may have contributed to the poor decision-making process that eventually led to Swissair's collapse.

Marks & Spencer and British Airways

Another example of groupthink from the corporate world is illustrated in the United Kingdom-based companies Marks & Spencer and British Airways. The negative impact of groupthink took place during the 1990s as both companies released globalization expansion strategies. Researcher Jack Eaton's content analysis of media press releases revealed that all eight symptoms of groupthink were present during this period. The most predominant symptom of groupthink was the illusion of invulnerability as both companies underestimated potential failure due to years of profitability and success during challenging markets. Up until the consequence of groupthink erupted they were considered blue chips and darlings of the London Stock Exchange. During 1998–1999 the price of Marks & Spencer shares fell from 590 to less than 300 and that of British Airways from 740 to 300. Both companies had already featured prominently in the UK press and media for more positive reasons to do with national pride in their undoubted sector-wide performance.

Sports

Recent literature of groupthink attempts to study the application of this concept beyond the framework of business and politics. One particularly relevant and popular arena in which groupthink is rarely studied is sports. The lack of literature in this area prompted Charles Koerber and Christopher Neck to begin a case-study investigation that examined the effect of groupthink on the decision of the Major League Umpires Association (MLUA) to stage a mass resignation in 1999. The decision was a failed attempt to gain a stronger negotiating stance against Major League Baseball. Koerber and Neck suggest that three groupthink symptoms can be found in the decision-making process of the MLUA. First, the umpires overestimated the power that they had over the baseball league and the strength of their group's resolve. The union also exhibited some degree of closed-mindedness with the notion that MLB is the enemy. Lastly, there was the presence of self-censorship; some umpires who disagreed with the decision to resign failed to voice their dissent. These factors, along with other decision-making defects, led to a decision that was suboptimal and ineffective.

Recent developments

Ubiquity model

Researcher Robert Baron (2005) contends that the connection between certain antecedents which Janis believed necessary has not been demonstrated by the current collective body of research on groupthink. He believes that Janis' antecedents for groupthink are incorrect, and argues that not only are they "not necessary to provoke the symptoms of groupthink, but that they often will not even amplify such symptoms". As an alternative to Janis' model, Baron proposed a ubiquity model of groupthink. This model provides a revised set of antecedents for groupthink, including social identification, salient norms, and low self-efficacy.

General group problem-solving (GGPS) model

Aldag and Fuller (1993) argue that the groupthink concept was based on a "small and relatively restricted sample" that became too broadly generalized. Furthermore, the concept is too rigidly staged and deterministic. Empirical support for it has also not been consistent. The authors compare groupthink model to findings presented by Maslow and Piaget; they argue that, in each case, the model incites great interest and further research that, subsequently, invalidate the original concept. Aldag and Fuller thus suggest a new model called the general group problem-solving (GGPS) model, which integrates new findings from groupthink literature and alters aspects of groupthink itself. The primary difference between the GGPS model and groupthink is that the former is more value neutral and more political.

Reexamination

OLater scholars have re-assessed the merit of groupthink by reexamining case studies that Janis originally used to buttress his model. Roderick Kramer (1998) believed that, because scholars today have a more sophisticated set of ideas about the general decision-making process and because new and relevant information about the fiascos have surfaced over the years, a reexamination of the case studies is appropriate and necessary. He argues that new evidence does not support Janis' view that groupthink was largely responsible for President Kennedy's and President Johnson's decisions in the Bay of Pigs Invasion and U.S. escalated military involvement in the Vietnam War, respectively. Both presidents sought the advice of experts outside of their political groups more than Janis suggested. Kramer also argues that the presidents were the final decision-makers of the fiascos; while determining which course of action to take, they relied more heavily on their own construals of the situations than on any group-consenting decision presented to them. Kramer concludes that Janis' explanation of the two military issues is flawed and that groupthink has much less influence on group decision-making than is popularly believed.

Groupthink, while it is thought to be avoided, does have some positive effects. A case study by Choi and Kim shows that with group identity, group performance has a negative correlation with defective decision making. This study also showed that the relationship between groupthink and defective decision making was insignificant. These findings mean that in the right circumstances, groupthink does not always have negative outcomes. It also questions the original theory of groupthink.

Reformulation

Whyte (1998) suggests that collective efficacy plays a large unrecognised role in groupthink because it causes groups to become less vigilant and to favor risks, two particular factors that characterize groups affected by groupthink. McCauley recasts aspects of groupthink's preconditions by arguing that the level of attractiveness of group members is the most prominent factor in causing poor decision-making. The results of Turner's and Pratkanis' (1991) study on social identity maintenance perspective and groupthink conclude that groupthink can be viewed as a "collective effort directed at warding off potentially negative views of the group". Together, the contributions of these scholars have brought about new understandings of groupthink that help reformulate Janis' original model.

Sociocognitive theory

According to a new theory many of the basic characteristics of groupthink – e.g., strong cohesion, indulgent atmosphere, and exclusive ethos – are the result of a special kind of mnemonic encoding (Tsoukalas, 2007). Members of tightly knit groups have a tendency to represent significant aspects of their community as episodic memories and this has a predictable influence on their group behavior and collective ideology.

Foreign interventions by the United States

The United States has been involved in numerous foreign interventions throughout its history. There have been two dominant schools of thought in the United States about foreign policy, namely interventionism and isolationism which either encourage or discourage foreign intervention, both military, diplomatic, and economic, respectively.

The 19th century formed the roots of United States interventionism, which at the time was largely driven by economic opportunities in the Pacific and Spanish-held Latin America along with the Monroe Doctrine, which saw the U.S. seek a policy to resist European colonialism in the Western hemisphere.

Post-colonial

The 19th century saw the United States transition from an isolationist, post-colonial regional power to a Trans-Atlantic and Trans-Pacific power.

The first and second Barbary Wars of the early 19th century were the first nominal foreign wars waged by the United States post-Independence. Directed against the Barbary States of North Africa, the Barbary Wars were fought to end piracy against American-flagged ships in the Mediterranean Sea, similar to the Quasi-War with the French Republic.

The founding of Liberia was privately sponsored by American groups, primarily the American Colonization Society, but the country enjoyed the support and unofficial cooperation of the United States government.

Notable 19th century interventions included:

  • Repeated U.S. interventions in Chile, starting in 1811, the year after its independence from Spain.
  • 1846 to 1848: Mexico and the United States warred over Texas, California and what today is the American Southwest but was then part of Mexico (see Mexican–American War). During this war, U.S. troops invaded and occupied parts of Mexico, including Veracruz and Mexico City.
  • 1854: Matthew Perry negotiated a treaty opening Japan to the West with the Convention of Kanagawa. The U.S. advanced the Open Door Policy that guaranteed equal economic access to China and support of Chinese territorial and administrative integrity.
  • 1871: The U.S. dispatched an expeditionary force to Korea after failed attempts to ascertain the fate of the armed merchant ship General Sherman, which was attacked during an unsuccessful attempt to open up trade with the isolationist kingdom in 1866. After being ambushed, the 650-man American expeditionary force launched a punitive campaign, capturing and occupying several Korean forts and killing over 200 Korean troops.
  • 1898: The short but decisive Spanish–American War saw overwhelming American victories at sea and on land against the Spanish Kingdom. The U.S. Army, relying significantly on volunteers and state militia units, invaded and occupied Spanish-controlled Cuba, subsequently granting it independence. The peace treaty saw Spain cede control over its colonies of Puerto Rico, Guam, and the Philippines to the United States. The U.S. Navy set up coaling stations there and in Hawaii.

The early decades of the 20th century saw a number of interventions in Latin America by the U.S. government often justified under the Roosevelt Corollary to the Monroe Doctrine. President William Howard Taft viewed Dollar diplomacy as a way for American corporations to benefit while assisting in the national security goal of preventing European powers from filling any possible financial or power vacuum.

  • 1898 to 1935: The United States launched minor interventions into Latin America. These included military presence in Cuba, Panama with the Panama Canal Zone, Haiti (1915–35), Dominican Republic (1916–24) and Nicaragua (1912–1925) & (1926–33). The U.S. Marine Corps began to specialize in long-term military occupation of these countries, primarily to safeguard customs revenues which were the cause of local civil wars.
  • 1899 to 1901: The U.S. organized the China Relief Expedition during the Boxer Rebellion, which saw an eight-nation alliance put down a rebellion by the Boxer secret society and toppled the Qing dynasty's Imperial Army.
  • 1899 to 1902: The Philippine–American War saw Filipino revolutionaries revolt against American rule following the Spanish-American War. The U.S. Army deployed 100,000 (mostly National Guard) troops under General Elwell Otis to the Philippines, leading the poorly armed and poorly trained rebels to break off into armed bands. The insurgency collapsed in March 1901 when the leader Emilio Aguinaldo was captured by General Frederick Funston and his Macabebe allies.
  • 1899 to 1913: The Moro Rebellion saw the annexation of the Philippines by the United States.
  • 1901: The Platt Amendment amended a treaty between the U.S. and Cuba after the Spanish–American War, virtually making Cuba a U.S. protectorate. The amendment outlined conditions for the U.S. to intervene in Cuban affairs and permitted the United States to lease or buy lands for the purpose of the establishing naval bases, including Guantánamo Bay.
  • 1903: U.S.-backed independence of Panama from Colombia in order to build the Panama Canal; Hay–Bunau-Varilla Treaty
  • 1904: When European governments began to use force to pressure Latin American countries to repay their debts, Theodore Roosevelt announced his "Corollary" to the Monroe Doctrine, stating that the United States would intervene in the Western Hemisphere should Latin American governments prove incapable or unstable.

World War II

During the Second World War, the United States deployed troops to fight in both Europe, North Africa, and the Pacific. The U.S. was a key participant in many battles, including the Battle of Midway, the Normandy landings, and the Battle of the Bulge. In the time period between December 7, 1941 to September 2, 1945, more than 400,000 Americans were killed in the conflict. After the war, American and Allied troops occupied both Germany and Japan.

The United States also gave economic support to a large number of countries and movements who were opposed to the Axis powers. This included the Lend-Lease program, which "lent" a wide array of resources and weapons to many countries, especially Great Britain and the USSR, ostensibly to be repaid after the war. In practice, the United States frequently either did not push for repayment or "sold" the goods for a nominal price, such as 10% of their value. Significant aid was also sent to France and Taiwan, and resistance movements in countries occupied by the Axis.

Cold War

Following the Second World War, the U.S. helped form the North Atlantic Treaty Organization in 1949 to resist communist expansion and supported resistance movements and dissidents in the communist regimes of Central and Eastern Europe and the Soviet Union during a period known as the Cold War. One example is the counterespionage operations following the discovery of the Farewell Dossier which some argue contributed to the fall of the Soviet regime. After Joseph Stalin instituted the Berlin Blockade, the United States, Britain, France, Canada, Australia, New Zealand and several other countries began the massive "Berlin airlift", supplying West Berlin with up to 4,700 tons of daily necessities. U.S. Air Force pilot Gail Halvorsen created "Operation Vittles", which supplied candy to German children. In May 1949, Stalin backed down and lifted the blockade. The U.S. spent billions to rebuild Europe and aid global development through programs such as the Marshall Plan.

When democratically elected Guatemalan President Jacobo Árbenz attempted a modest redistribution of land, he was overthrown in the 1954 CIA Guatemalan coup d'état

In 1945, the United States and Soviet Union occupied Korea to disarm the Japanese Armed Forces that occupied the Korean peninsula. The US and Soviet Union split the country at the 38th parallel and each installed a government, with the Soviet Union installing a Stalinist Kim Il-sung in North Korea and in South Korea, US supported anti-communist Syngman Rhee was elected president in 1948. Both leaders were authoritarian dictators. Tensions between the North and South erupted into full scale war in 1950 when North Korean forces invaded the South. From 1950 to 1953, U.S. and United Nations forces fought communist Chinese and North Korean troops in the Korean War. The war resulted in 36,574 American deaths and 2-3 million Korean deaths. The war ended in a stalemate with the Korean peninsula devastated and every major city in ruins. North Korea was among the most heavily bombed countries in history. Fighting ended on 27 July 1953 when the Korean Armistice Agreement was signed. The agreement created the Korean Demilitarized Zone (DMZ) to separate North and South Korea, and allowed the return of prisoners. However, no peace treaty was ever signed, and the two Koreas are technically still at war. U.S. troops have remained in South Korea to deter further conflict.

During the Cold War, the U.S. frequently used the Central Intelligence Agency (CIA) for covert and clandestine operations against governments considered unfriendly to U.S. interests, especially in the Middle East, Latin America, and Africa. In 1949, during the Truman administration, a coup d'état overthrew an elected parliamentary government in Syria, which had delayed approving an oil pipeline requested by U.S. international business interests in that region. The exact role of the CIA in the coup is controversial, but it is clear that U.S. governmental officials, including at least one CIA officer, communicated with Husni al-Za'im, the coup's organizer, prior to the March 30 coup, and were at least aware that it was being planned. Six weeks later, on May 16, Za'im approved the pipeline.

In the early 1950s, the CIA spearheaded Project FF, a clandestine effort to pressure Egyptian king Farouk I into embracing pro-American political reforms. After he resisted, the project shifted towards deposing him, and Farouk was subsequently overthrown in a military coup in 1952. In 1953, under U.S. President Dwight Eisenhower, the CIA helped Shah Mohammad Reza Pahlavi of Iran remove the democratically elected Prime Minister, Mohammed Mossadegh. Supporters of U.S. policy claimed that Mossadegh had ended democracy through a rigged referendum.

In 1952, the CIA launched Operation PBFortune and, in 1954, Operation PBSuccess to depose the democratically elected Guatemalan President Jacobo Árbenz and ended the Guatemalan Revolution. The coup installed the military dictatorship of Carlos Castillo Armas, the first in a series of U.S.-backed dictators who ruled Guatemala. Guatemala subsequently plunged into a civil war that cost thousands of lives and ended all democratic expression for decades.

The CIA armed an indigenous insurgency in order to oppose the invasion and subsequent control of Tibet by China and sponsored a failed revolt against Indonesian President Sukarno in 1958. As part of the Eisenhower Doctrine, the U.S. also deployed troops to Lebanon in Operation Blue Bat. President Eisenhower also imposed embargoes on Cuba in 1958.

Covert operations continued under President John F. Kennedy and his successors. In 1961, the CIA attempted to depose Cuban president Fidel Castro through the Bay of Pigs Invasion, however the invasion was doomed to fail when President Kennedy withdrew overt U.S. air support at the last minute. During Operation Mongoose, the CIA aggressively pursued its efforts to overthrow Castro's regime by conducting various assassination attempts on Castro and facilitating U.S.-sponsored terrorist attacks in Cuba. American efforts to sabotage Cuba's national security played a significant role in the events leading up to the Cuban Missile Crisis, which saw the U.S. blockade the island during a confrontation with the Soviet Union. The CIA also considered assassinating Congolese leader Patrice Lumumba with poisoned toothpaste (although this plan was aborted).

In 1961, the CIA sponsored the assassination of Rafael Trujillo, former dictator of the Dominican Republic. After a period of instability, U.S. troops intervened the Dominican Republic into the Dominican Civil War (April 1965) to prevent a takeover by supporters of deposed left wing president Juan Bosch who wer fighting supporters of General Elías Wessin y Wessin. The soldiers were also deployed to evacuate foreign citizens. The U.S. deployed 22,000 soldiers and suffered 44 dead. The OAS also deployed soldiers to the conflict through the Inter-American Peace Force. U.S. soldiers were gradually withdrawn from May onwards. The war officially ended on September 3, 1965. The first postwar elections were held on July 1, 1966, conservative Joaquín Balaguer defeated former president Juan Bosch.

President John F. Kennedy meeting with Cheddi Jagan in October 1961. The trip was a political disaster for Jagan, who failed to sooth the suspicions of Kennedy and Congress by equivocating on Cold War issues.

At the end of the Eisenhower administration, a campaign was initiated to deny Cheddi Jagan power in an independent Guyana. This campaign was intensified and became something of an obsession of John F. Kennedy, because he feared a "second Cuba". By the time Kennedy took office, the United Kingdom was ready to decolonize British Guiana and did not fear Jagan's political leanings, yet chose to cooperate in the plot for the sake of good relations with the United States. The CIA cooperated with AFL-CIO, most notably in organizing an 80-day general strike in 1963, backing it up with a strike fund estimated to be over $1 million. The Kennedy Administration put pressure on Harold Macmillan's government to help in its effort, ultimately attaining a promise on July 18, 1963, that Macmillan's government would unseat Jagan. This was achieved through a plan developed by Duncan Sandys whereby Sandys, after feigning impartiality in a Guyanese dispute, would decide in favor of Forbes Burnham and Peter D'Aguiar, calling for new elections based on proportional representation before independence would be considered, under which Jagan's opposition would have better chances to win. The plan succeeded, and the Burnham-D'Aguiar coalition took power soon after winning the election on December 7, 1964. The Johnson administration later helped Burnham fix the fraudulent election of 1968—the first election after decolonization in 1966. To guarantee Burnham's victory, Johnson also approved a well-timed Food for Peace loan, announced some weeks before the election so as to influence the election but not to appear to be doing so. U.S.–Guyanese relations cooled in the Nixon administration. Henry Kissinger, in his memoirs, dismissed Guyana as being "invariably on the side of radicals in Third World forums."

From 1965 to 1973, U.S. troops fought at the request of the governments of South Vietnam, Laos, and Cambodia during the Vietnam War against the military of North Vietnam and against Viet Cong, Pathet Lao, and Khmer Rouge insurgents. President Lyndon Johnson escalated U.S. involvement following the Gulf of Tonkin Resolution. North Vietnam invaded Laos in 1959, and used 30,000 men to build invasion routes through Laos and Cambodia. North Vietnam sent 10,000 troops to attack the south in 1964, and this figure increased to 100,000 in 1965. By early 1965, 7,559 South Vietnamese hamlets had been destroyed by the Viet Cong. The CIA organized Hmong tribes to fight against the Pathet Lao, and used Air America to "drop 46 million pounds of foodstuffs....transport tens of thousands of troops, conduct a highly successful photoreconnaissance program, and engage in numerous clandestine missions using night-vision glasses and state-of-the-art electronic equipment." After sponsoring a coup against Ngô Đình Diệm, the CIA was asked "to coax a genuine South Vietnamese government into being" by managing development and running the Phoenix Program that killed thousands of insurgents. North Vietnamese forces attempted to overrun Cambodia in 1970, to which the U.S. and South Vietnam responded with a limited incursion. The U.S. bombing of Cambodia, called Operation Menu, proved controversial. Although David Chandler argued that the bombing "had the effect the Americans wanted--it broke the communist encirclement of Phnom Penh," others have claimed it boosted recruitment for the Khmer Rouge. North Vietnam violated the Paris Peace Accords after the US withdrew, and all of Indochina had fallen to communist governments by late 1975.

Chilean General Augusto Pinochet with George H. W. Bush

In 1975 it was revealed by the Church Committee that the United States had covertly intervened in Chile from as early as 1962, and that from 1963 to 1973, covert involvement was "extensive and continuous". In 1970, at the request of President Richard Nixon, the CIA planned a "constitutional coup" to prevent the election of Marxist leader Salvador Allende in Chile, while secretly encouraging Chilean generals to act against him. The CIA changed its approach after the murder of Chilean general René Schneider, offering aid to democratic protestors and other Chilean dissidents. Allende was accused of supporting armed groups, torturing detainees, conducting illegal arrests, and muzzling the press. However, Peter Kornbluh asserts that the CIA destabilized Chile and helped create the conditions for the 1973 Chilean coup d'état, which led to years of dictatorship under Augusto Pinochet.

In 1973, Nixon authorized Operation Nickel Grass, an overt strategic airlift to deliver weapons and supplies to Israel during the Yom Kippur War, after the Soviet Union began sending arms to Syria and Egypt. From 1972–5, the CIA armed Kurdish rebels fighting the Ba'athist government of Iraq.

Months after the Saur Revolution brought a communist regime to power in Afghanistan, the U.S. began offering limited financial aid to Afghan dissidents through Pakistan's Inter-Services Intelligence, although the Carter administration rejected Pakistani requests to provide arms. After the Iranian Revolution, the United States sought rapprochement with the Afghan government—a prospect that the USSR found unacceptable due to the weakening Soviet leverage over the regime. The Soviets invaded Afghanistan on December 24, 1979 to depose Hafizullah Amin, and subsequently installed a puppet regime. Disgusted by the collapse of detente, President Jimmy Carter began covertly arming Afghan mujahideen in a program called Operation Cyclone.

This program was greatly expanded under President Ronald Reagan as part of the Reagan Doctrine. As part of this doctrine, the CIA also supported the UNITA movement in Angola, the Solidarity movement in Poland, the Contra revolt in Nicaragua, and the Khmer People's National Liberation Front in Cambodia. U.S. and UN forces later supervised free elections in Cambodia. Under Reagan, the US sent troops to Lebanon during the Lebanese Civil War as part of a peace-keeping mission. The U.S. withdrew after 241 servicemen were killed in the Beirut barracks bombing. In Operation Earnest Will, U.S. warships escorted reflagged Kuwaiti oil tankers to protect them from Iranian attacks during the Iran–Iraq War. The United States Navy launched Operation Praying Mantis in retaliation for the Iranian mining of the Persian Gulf during the war and the subsequent damage to an American warship. The attack helped pressure Iran to agree to a ceasefire with Iraq later that summer, ending the eight-year war. Under Carter and Reagan, the CIA repeatedly intervened to prevent right-wing coups in El Salvador and the U.S. frequently threatened aid suspensions to curtail government atrocities in the Salvadoran Civil War. As a result, the death squads made plans to kill the U.S. Ambassador. In 1983, after an internal power struggle ended with the deposition and murder of revolutionary Prime Minister Maurice Bishop, the U.S. invaded Grenada in Operation Urgent Fury and held free elections. In 1986, the U.S. bombed Libya in response to Libyan involvement in international terrorism. President George H. W. Bush ordered the invasion of Panama (Operation Just Cause) in 1989 and deposed dictator Manuel Noriega.

A 2016 study by Carnegie Mellon University professor Dov Levin found that the United States intervened in 81 foreign elections between 1946 and 2000, with the majority of those being through covert, rather than overt, actions. A 2021 review of the existing literature found that foreign interventions since World War II tend overwhelmingly to fail to achieve their purported objectives.

Post-Cold War

Destroyed vehicles along the Highway of Death in 1991, a legacy of the Gulf War.

In 1990-91, the U.S. intervened in Kuwait after a series of failed diplomatic negotiations, and led a coalition to repel invading Iraqi forces led by Iraqi dictator Saddam Hussein, in what became known as the Gulf War. On 26 February 1991, the coalition succeeded in driving out the Iraqi forces. The U.S., UK, and France responded to popular Shia and Kurdish demands for no-fly zones, and intervened and created no-fly zones in Iraq's south and north to protect the Shia and Kurdish populations from Saddam's regime. The no-fly zones cut off Saddam from the country's Kurdish north, effectively granting autonomy to the Kurds, and would stay active for 12 years until the 2003 invasion of Iraq.

In the 1990s, the U.S. intervened in Somalia as part of UNOSOM I, a United Nations humanitarian relief operation that resulted in saving hundreds of thousands of lives. During the 1993 Battle of Mogadishu, two U.S. helicopters were shot down by rocket-propelled grenade attacks to their tail rotors, trapping soldiers behind enemy lines. This resulted in a brief but bitter street firefight; 18 Americans and more than 300 Somalis were killed.

Under President Bill Clinton, the U.S. participated in Operation Uphold Democracy, a UN mission to reinstate the elected president of Haiti, Jean-Bertrand Aristide, after a military coup. In 1995, Clinton ordered U.S. and NATO aircraft to attack Bosnian Serb targets to halt attacks on UN safe zones and to pressure them into a peace accord. Clinton deployed U.S. peacekeepers to Bosnia in late 1995, to uphold the subsequent Dayton Agreement. In response to the 1998 al-Qaeda bombings of U.S. embassies in East Africa that killed a dozen Americans and hundreds of Africans, Clinton ordered cruise missile strikes on targets in Afghanistan and Sudan. First was the Sudanese Al-Shifa pharmaceutical factory, suspected of assisting Osama Bin Laden in making chemical weapons. The second was Bin Laden's terrorist training camps in Afghanistan.

Also, to stop the ethnic cleansing and genocide of Albanians by nationalist Serbians in the former Federal Republic of Yugoslavia's province of Kosovo, Clinton authorized the use of U.S. Armed Forces in a NATO bombing campaign against Yugoslavia in 1999, named Operation Allied Force.

The CIA was involved in the failed 1996 coup attempt against Saddam Hussein.

War on terror and Arab Spring

The U.S. Navy participated in the Saudi Arabian-led naval blockade of Yemen.
 

After the September 11, 2001 attacks, under President George W. Bush, the U.S. and NATO launched the War on Terror, which saw an intervention to depose the Taliban government in the Afghan War and launch drone strikes and special operations in Afghanistan, Pakistan, Yemen, and Somalia against suspected terrorist targets. In 2003, the U.S. and a multi-national coalition invaded Iraq to depose Saddam Hussein. As of 2021, Afghanistan continues to host U.S. and NATO counter-terror and counterinsurgency operations under the aegis of Operation Resolute Support and Operation Freedom's Sentinel, while the Iraq War officially ended on December 18, 2011. In war-ravaged Colombia, the U.S. used large amounts of aid and provided counterinsurgency training to enhance stability and reduce violence, in what has been called "the most successful nation-building exercise by the United States in this century".

In 2011, the U.S. intervened in the First Libyan Civil War by providing air support to rebel forces. There was also speculation in The Washington Post that President Barack Obama issued a covert action, discovering in March 2011 that Obama authorized the CIA to carry out a clandestine effort to provide arms and support to the Libyan opposition. Muammar Gaddafi was ultimately overthrown and killed.

Beginning around 2012, under the aegis of operation Timber Sycamore and other clandestine activities, CIA operatives and U.S. special operations troops trained and armed nearly 10,000 Syrian rebel fighters at a cost of $1 billion a year until it was phased out in 2017 by the Trump administration.

2013–2014 saw the rise of the Islamic State in Iraq and the Levant (ISIL) terror organization in the Middle East. In June 2014, the U.S. re-intervened into Iraq and began airstrikes against ISIL there in response to prior gains by the terrorist group that threatened U.S. assets and Iraqi government forces. This was followed by more airstrikes on ISIL in Syria in September 2014, where the U.S.-led coalition targeted ISIL positions throughout the war-ravaged nation. Initial airstrikes involved fighters, bombers, and launching Tomahawk cruise missiles.

In March 2015, Obama declared that he had authorized U.S. forces to provide logistical and intelligence support to the Saudis in their military intervention in Yemen, establishing a "Joint Planning Cell" with Saudi Arabia.
