the Cold War
The Cold War was a period of political tension and military rivalry between the United States and the Soviet Union that lasted from the late 1940s until the early 1990s. It was characterized by a struggle for global influence, with both superpowers promoting their ideologies: capitalism in the U.S. and communism in the Soviet Union.
During this time, there were no direct military confrontations between the two nations, but they engaged in proxy wars, arms races, and espionage. Key events included the Cuban Missile Crisis, the Vietnam War, and the formation of military alliances like NATO and the Warsaw Pact.
