What does the Cold War have to do with communism

The Cold War was a recent era in international relations with a bipolar order (1947-1991). Two superpowers vied for world influence and hegemony. One was the Soviet Union, which was a communist giant. The other was the United States of America. The conflict was also ideological and political; each represented a different model of social, economic and political organization of society. Marxism-Leninism was the official Soviet ideology.

Basically, the United States was trying to oppose the Soviet Union's policies of communism, and that was the basis of the Cold War. The U. S. and U. K. thought that communism was spreading uncontrollably and that they had to stop the spread which was taking over East Russia and other parts of the world.
