Communism

Commusism played a huge part in the Cold War. The Soviet Union had to tighten up their grip on the Eastern Front because they needed more communist countries. Soviet Union had Satellite Nations which were nations that were controlled by communist nations. Stalin which was the Soviet Unions leader during the cold war took over the satellite nations industries. Soviets were now a major threat to the U.S. North Korea was communist and West Berlin was a Satellite Nation.
Communist Government was corrupt, so the government controlled anything they could take your car if they needed it, they could take over the business and you could lose your job. Communism was spreading to China, Korea and other countries.
