By 1948, as a result of the Cold War between the Soviet Union and the U.S., Korea was split into two regions, with separate governments, each claiming to be the legitimate government of Korea, and neither side accepting the border as permanent. In 1950 fighting broke out between Communists and Republicans that soon involved troops from China (on the Communists' side), and the United States and 15 allied countries (on the Republicans' side).

. Mao Zedong's decision to take on the U.S. in the Korean War was a direct attempt to confront what the Communist bloc viewed as the strongest anti-Communist power in the world, undertaken at a time when the Chinese Communist regime was still consolidating its own power after winning the Chinese Civil War. The first figure to propose the domino theory was President Harry S. Truman in the 1940s, where he introduced the theory in order to “justify sending military aid to Greece and Turkey.” However, the domino theory was popularized by President Dwight D. Eisenhower when he applied it to Southeast Asia, especially South Vietnam. Moreover, the domino theory was utilized as one of the key arguments in the “Kennedy and Johnson administrations during the 1960s to justify increasing American military involvement in the Vietnam War.” In May 1954, the

During the summer of 1963, Buddhists protested about the harsh treatment they were receiving under the Diem government of South Vietnam. Such actions of the South Vietnamese government made it difficult for the Kennedy administration's strong support for President Diem. President Kennedy was in a tenuous position, trying to contain Communism in Southeast Asia, but on the other hand, supporting an anti-Communist government that was not popular with its domestic citizens and was guilty of acts objectionable to the American public. The Kennedy administration intervened in Vietnam in the early 1960s to, among other reasons, keep the South Vietnamese "domino" from falling. When Kennedy came to power there was concern that the communist-led

Arguments in favor of the domino theory

The primary evidence for the domino theory is the spread of communist rule in three Southeast Asian countries in 1975, following the communist takeover of Vietnam: South Vietnam (by the Viet Cong), Laos (by the Pathet Lao), and Cambodia (by the
Khmer Rouge The Khmer Rouge (; ; km, ខ្មែរក្រហម, ; ) is the name that was popularly given to members of the Communist Party of Kampuchea (CPK) and by extension to the regime through which the CPK ruled Cambodia between 1975 and 1979 ...

argued that the prospects for a domino effect, though high in the 1950s and early 1960s, were weakened in 1965 when the Indonesian Communist Party was destroyed via death squads in the Indonesian genocide. However, proponents believe that the efforts during the containment (i.e., Domino Theory) period ultimately led to the demise of the Soviet Union and the end of the Cold War. Some supporters of the domino theory note the history of communist governments supplying aid to communist revolutionaries in neighboring countries. For instance, China supplied the Viet Minh and later the North Vietnamese army, with troops and supplies, and the Soviet Union supplied them with tanks and heavy weapons. The fact that the Pathet Lao and Khmer Rouge were both originally part of the Vietminh, not to mention Hanoi's support for both in conjunction with the Viet Cong, also give credence to the theory. The Soviet Union also heavily supplied Sukarno with military supplies and advisors from the time of the Guided Democracy in Indonesia, especially during and after the 1958 civil war in Sumatra.


Arguments that criticize the domino theory

* In the spring of 1995, former US Secretary of Defense Robert McNamara said he believed the domino theory was a mistake. Professor Tran Chung Ngoc, an overseas Vietnamese living in the US, said: "The US does not have any plausible reason to intervene in Vietnam, a small, poor, undeveloped country that does not have any ability to do anything that could harm America. Therefore, the US intervention in Vietnam regardless of public opinion and international law is "using power over justice", giving itself the right to intervene anywhere that America wants."


Significance of the domino theory

The domino theory is significant because it underlines the importance of alliances, which may vary from rogue alliances to bilateral alliances. This implies that the domino theory is useful in evaluating a country’s intent and purpose of forging an alliance with others, including a cluster of other countries within a particular region. While the intent and purpose may differ for every country, Victor Cha portrays the asymmetrical bilateral alliance between the United States and countries in East Asia as a strategic approach, where the United States is in control and power to either mobilize or stabilize its allies. This is supported by how the United States created asymmetrical bilateral alliances with the Republic of Korea, Republic of China and Japan “not just to contain but also constrain potential ‘rogue alliances’ from engaging in adventurist behavior that might it into larger military contingencies in the region or that could trigger a domino effect, with Asian countries falling to communism.” Since the United States struggled with the challenge of “rogue alliances and the threat of falling dominoes combined to produce a dreaded entrapment scenario for the United States,” the domino theory further underscores the importance of bilateral alliances in international relations. This is evident in how the domino theory provided the United States with a coalition approach, where it “fashioned a series of deep, tight bilateral alliances” with Asian countries including Taiwan, South Korea, and Japan to “control their ability to use force and to foster material and political dependency on the United States.” Hence, this indicates that the domino theory assists in observing the effect of forged alliances as a stepping stone or stumbling block within international relations. This underscores the correlation between domino theory and path dependency, where a retrospective collapse of one country falling to communism may not only have adverse effects to other countries but more importantly, on one’s decision-making scope and competence in overcoming present and future challenges. Therefore, the domino theory is indubitably a significant theory which deals with the close relationship between micro-cause and macro-consequence, where it suggests such macro-consequences may result in long-term repercussions.

American hostages were seized aboard the SS ''Mayaguez'' (off Cambodia) and in Tehran. The Soviet Army invaded Afghanistan. There is no obvious connection with the Vietnam War, but there is little doubt that the defeat of a superpower encouraged our enemies to undertake acts of aggression that they might otherwise have shied away from." In addition, this theory can be further bolstered by the rise in terrorist incidents by left-wing terrorist groups in Western Europe, funded in part by Communist governments, between the 1960s and 1980s.
