1. The Origins of the Cold War

2. Differences between communism and capitalism.
US and Soviet Union were allies in WWII.
After WWII, Europe was in ruins, and former colonial empires were crumbling.
This set the scene for increased competition between the two superpowers, the
U.S. and the U.S.S.R.
The Soviet Red Army remained in Eastern Europe after the war, which led to the
Soviet Bloc.
At the same time, the United States developed policies of
containment – in particular, the Truman Doctrine and the Marshall Plan.
