Answer:

Here are some possible factors that contributed to the Cold War:

1) The Soviet Union refused to become part of the UN for a long time.

2) Stalin felt that America and Britain were delaying D-Day, causing more Soviet losses in a plot to weaken the Soviet army. Almost sixty times more Soviets died in the war than the Americans.

3) The “Big Three” clashed during the Tehran Conference about Poland and other Eastern European countries that bordered with Germany. Stalin felt independent countries were a security threat to Russia because they have been weak enough to let Germany attack the Soviet Union through them several times. Britain and America wanted these countries to be independent, not under communist rule.

4) The Soviets and Germans had a non-aggression pact in the first two years of the war with a secret protocol

5) The support of the Western allies of the Atlantic CharterThe Eastern Bloc of Soviet satellite states that was created

6) The Allies allowing Germany to rebuild an industry and army, scrapping the Marshall and Morgenthau plans

7) The Allies allowing Germany to join NATOAmerican and British fears of communist attacks and the Soviet Union’s dislike of capitalism

8) The Soviet Union’s fear of America’s nuclear weapons and refusal to share their nuclear secrets

9) The Soviet Union’s actions in Eastern Germany, in the Soviet zone

10) The USSR’s aim to promote communism across the world and their expansion into Eastern Europe.
