Why did the Cold War start?

Answer 1

One of the reasons that the cold war started was nuclear weapons. When two countries both have that much destructive power, they begin to wonder if they trust that sort of power in the other country's hands.

Ideological differences were another big reason... the US hated Communism, and the USSR hated Capitalism. Both sides wanted to spread their form of government to other countries, so there was a lot of tension there.

I think there was also personal dislike between world leaders, and that is how it began.

Answer 2

The cold war, an ideological conflict between Communist and non-Communist countries, started after World War II (1939-45) when the Allies (United States, Britain, France, and the Soviet Union) disagreed over how to govern occupied Germany. Although the Soviet Union and the Western Allies were supposed to rule Germany jointly, the arrangement was beset by the spread of communism. During the war Soviet leaders had joined the United States and Western European countries to fight the Germans, but the Soviets supported communism, a political and economic system that they believed had to combat and overtake capitalism, which was practiced elsewhere in the Western world. By 1947 the United States had formulated policy to prevent the Soviet Union from exporting communism to other countries.
