Cold War: The Cold War was a prolonged period of geopolitical tension between the Soviet Union and the United States, along with their respective allies, following World War II. This ideological conflict was marked by a struggle for global influence, characterized by military competition, nuclear arms races, and proxy wars rather than direct confrontation.
