CLEP US History II

Answer: C - The Iron Curtain was the political and cultural barrier that existed during the Cold War between the communist Soviet Union and the democratic United States. Though the Americans and Soviets worked together during the war, the relationship quickly soured after peace was won, leading to an ideological war that lasted more than four decades. The proliferation of nuclear weapons heightened tensions on both sides of the Iron Curtain, as the parties reached the brink of nuclear war multiple times.
