The domino theory is a geopolitical theory which posits that changes in the political structure of one country tend to spread to neighboring countries in a domino effect. It was prominent in the United States from the 1950s to the 1980s in the context of the Cold War, suggesting that if one country in a region came under the influence of communism, then the surrounding countries would follow. It was used by successive United States administrations during the Cold War as justification for American intervention around the world. U.S. President Dwight D. Eisenhower described the theory during a news conference on April 7, 1954, when referring to communism in Indochina as follows:
Finally, you have broader considerations that might follow what you would call the "falling domino" principle. You have a row of dominoes set up, you knock over the first one, and what will happen to the last one is the certainty that it will go over very quickly. So you could have a beginning of a disintegration that would have the most profound influences.
Brinkmanship or brinksmanship is the practice of trying to achieve an advantageous outcome by pushing dangerous events to the brink of active conflict. The maneuver of pushing a situation with the opponent to the brink succeeds by forcing the opponent to back down and make concessions rather than risk engaging in a conflict that would no longer be beneficial to either side. That might be achieved through diplomatic maneuvers, by creating the impression that one is willing to use extreme methods rather than concede. The tactic occurs in international politics, foreign policy, labor relations, contemporary military strategy, terrorism, and high-stakes litigation.
The Cold War was a period of global geopolitical tension and struggle for ideological and economic influence between the United States and the Soviet Union (USSR) and their respective allies, the Western Bloc and the Eastern Bloc, that started in 1947, two years after the end of World War II, and lasted until the fall of the Soviet Union in 1991. The term cold war is used because there was no direct fighting between the two superpowers, though each supported opposing sides in major regional conflicts known as proxy wars. Aside from the nuclear arms race starting in 1949 and conventional military deployment, the struggle for dominance was expressed indirectly via psychological warfare, propaganda campaigns, espionage, far-reaching embargoes, sports diplomacy, and technological competitions such as the Space Race.
The Sino-Soviet split was the gradual worsening of relations between the People's Republic of China (PRC) and the Union of Soviet Socialist Republics (USSR) during the Cold War. This was primarily caused by doctrinal divergences that arose from their different interpretations and practical applications of Marxism–Leninism, as influenced by their respective geopolitics during the Cold War of 1947–1991. In the late 1950s and early 1960s, Sino-Soviet debates about the interpretation of orthodox Marxism became specific disputes about the Soviet Union's policies of national de-Stalinization and international peaceful coexistence with the Western Bloc, which Chinese leader Mao Zedong decried as revisionism. Against that ideological background, China took a belligerent stance towards the Western world, and publicly rejected the Soviet Union's policy of peaceful coexistence between the Western Bloc and Eastern Bloc. In addition, Beijing resented the Soviet Union's growing ties with India due to factors such as the Sino-Indian border dispute, and Moscow feared that Mao was too nonchalant about the horrors of nuclear warfare.
The Cold War (1953–1962) refers to the period in the Cold War between the end of the Korean War in 1953 and the Cuban Missile Crisis in 1962. It was marked by tensions and efforts at détente between the US and Soviet Union.
During the Cold War, Canada was one of the western powers playing a central role in the major alliances. It was an ally of the United States, but there were several foreign policy differences between the two countries over the course of the Cold War. Canada's peacekeeping role during the Cold War has played a major role in its positive global image. The country served in every UN peacekeeping effort from its inception in 1948 until 1989. This resulted in Canada provided the greatest amount of UN peacekeepers during the Cold War.
During the Cold War, the Indochina Wars were a series of wars which were waged in Indochina from 1946 to 1991, by communist forces against the opponents. The term "Indochina" referred to former French Indochina, which included the current states of Vietnam, Laos, and Cambodia. In current usage, it applies largely to a geographic region, rather than to a political area. The wars included:
This is a timeline of the main events of the Cold War, a state of political and military tension after World War II between powers in the Western Bloc and powers in the Eastern Bloc.
The Cold War from 1979 to 1985, was a late phase of the Cold War marked by a sharp increase in hostility between the Soviet Union and the West. It arose from a strong denunciation of the Soviet invasion of Afghanistan in December 1979. With the election of Prime Minister Margaret Thatcher in 1979, and American President Ronald Reagan in 1980, a corresponding change in Western foreign policy approach toward the Soviet Union was marked by the rejection of détente in favor of the Reagan Doctrine policy of rollback, with the stated goal of dissolving Soviet influence in Soviet Bloc countries. During this time, the threat of nuclear war had reached new heights not seen since the Cuban Missile Crisis of 1962.
The Cold War (1962–1979) refers to the phase within the Cold War that spanned the period between the aftermath of the Cuban Missile Crisis in late October 1962, through the détente period beginning in 1969, to the end of détente in the late 1970s.
The aftermath of World War II saw the rise of two superpowers, the Soviet Union (USSR) and the United States (US). The aftermath of World War II was also defined by the rising threat of nuclear warfare, the creation and implementation of the United Nations as an intergovernmental organization, and the decolonization of Asia, Oceania, South America and Africa by European and East Asian powers, most notably by the United Kingdom, France, and Japan.
Contemporary history, in English-language historiography, is a subset of modern history that describes the historical period from about 1945 to the present. In the social sciences, contemporary history is also continuous with, and related to, the rise of postmodernity.
The aftermath of the Korean War set the tone for Cold War tension between superpowers. The Korean War was important in the development of the Cold War, as it showed that the two superpowers, United States and Soviet Union, could fight a "limited war" in a third country. The "limited war" or "proxy war" strategy was a feature of conflicts such as the Vietnam War and the Soviet War in Afghanistan, as well as wars in Angola, Greece, and the Middle East.
The following outline is provided as an overview of and topical guide to the Cold War:
North Vietnam, officially the Democratic Republic of Vietnam, was a socialist state in Southeast Asia that existed from 1945 to 1976, with formal sovereignty being fully recognized in 1954. A member of the Eastern Bloc, it opposed the French-supported State of Vietnam and later the Western-allied Republic of Vietnam. The DRV emerged victorious over South Vietnam in 1975 and ceased to exist the following year when it unified with the south to become the current Socialist Republic of Vietnam.
The effects of the Cold War on nation-states were numerous both economically and socially until its subsequent century. For example, in Russia, military spending was cut dramatically after 1991, which caused a decline from the Soviet Union's military-industrial sector. Such a dismantling left millions of employees throughout the former Soviet Union unemployed, which affected Russia's economy and military.
Though not officially a belligerent during the Korean War (1950–1953), the Soviet Union played a significant, covert role in the conflict. It provided material and medical services, as well as Soviet pilots and aircraft, most notably MiG-15 fighter jets, to aid the North Korean-Chinese army against the South Korean-United Nations Forces.
The post–Cold War era is a period of history that follows the end of the Cold War, which represents history after the dissolution of the Soviet Union in December 1991. This period saw many former Soviet republics become sovereign nations, as well as the introduction of market economies in eastern Europe. This period also marked the United States becoming the world's sole superpower.
The United States foreign policy of the Dwight D. Eisenhower administration, from 1953 to 1961, focused on the Cold War with the Soviet Union and its satellites. The United States built up a stockpile of nuclear weapons and nuclear delivery systems to deter military threats and save money while cutting back on expensive Army combat units. A major uprising broke out in Hungary in 1956; the Eisenhower administration did not become directly involved, but condemned the military invasion by the Soviet Union. Eisenhower sought to reach a nuclear test ban treaty with the Soviet Union, but following the 1960 U-2 incident the Kremlin canceled a scheduled summit in Paris.
The Cold War in Asia was a major dimension of the worldwide Cold War that shaped diplomacy and warfare from the mid-1940s to 1991. The main countries involved were the United States, the Soviet Union, China, North Korea, South Korea, North Vietnam, South Vietnam, Cambodia, Afghanistan, Iran, Iraq, India, Bangladesh, Pakistan, Indonesia, and Taiwan. In the late 1950s, divisions between China and the Soviet Union deepened, culminating in the Sino-Soviet split, and the two then vied for control of communist movements across the world, especially in Asia.
