Question

Why did tensions between the U.S. and the Soviet Union become so great after World War II?

Answer 1

The Cold War began as World War II was ending. American leaders saw the power and ambitions of the Soviet Union as a threat to our national security. The Cold War was a war of words and ideologies rather than a shooting war, although at times the Cold War turned "hot" as in Korea and Vietnam. Basically, the Cold War was a rivalry between the United States as leader of the western democracies, and the Soviet Union and the nations that were controlled by the communists.
