During the Cold War, what was the main concern of the United States?

The primary concern of the United States during the Cold War was communism. This ideological conflict was characterized by the U.S. and its allies opposing the spread of communism, which was primarily represented by the Soviet Union and its satellite states. The U.S. believed that the expansion of communism posed a significant threat to democracy and capitalism, leading to various policies aimed at containment. This included military interventions, support for anti-communist regimes, and economic aid to countries to prevent them from turning to communism.

The intense rivalry between the U.S. and the Soviet Union during this period influenced global politics, military strategies, and economic policies, leading to events such as the Korean War, the Vietnam War, and the Cuban Missile Crisis. Overall, the focus on communism significantly shaped U.S. domestic and foreign policy throughout the Cold War era.
