The post-World War II events are most closely associated with the fear of communism and the spread of Soviet influence, which led to the era known as the Cold War. This period was characterized by political and military tension between the Western Bloc, led by the United States and NATO allies, and the Eastern Bloc, led by the Soviet Union and its satellite states. The fear was not only of communism as an ideology but also of the potential for the Soviet Union to expand its control over other countries, which was seen as a threat to democracy and capitalism.

Following World War II, the world saw dramatic shifts in political power and the rise of the United States and the Soviet Union as superpowers. The ideological differences between these two nations were stark—with the U.S. championing capitalism and democracy, while the Soviet Union promoted communism and a centrally planned economy. This period saw a series of crises and conflicts, including the Berlin Blockade, the Korean War, the Vietnam War, the Cuban Missile Crisis, and numerous other proxy wars.

One of the most significant features of the Cold War was the arms race, particularly the development and stockpiling of nuclear weapons. This created a state of MAD (Mutually Assured Destruction), where both sides had the capability to annihilate each other, leading to a tense balance of power.

Domestically, especially in the United States, this period was marked by McCarthyism, a campaign against alleged communists in the U.S. government and other institutions, fueled by fears that communists were infiltrating the American government and society. The fear of communism also led to the formation of alliances such as NATO (North Atlantic Treaty Organization) and the Warsaw Pact, as well as the implementation of the Marshall Plan to rebuild Europe in a way that would prevent the spread of communism. The Cold War lasted until the early 1990s, when the Soviet Union collapsed, effectively ending the political and ideological tensions of that era.
