Who was at war with each other during the cold war and why

The Cold War was the tense relationship between the United States (and its allies), and the Soviet Union (the USSR and its allies) between the end of World War II and the fall of the Soviet Union. It is called the "Cold" War because the US and the USSR never actually fought each other directly.

The main enemies were the United States and the Soviet Union. Many causes that led to the outbreak of the Cold War have been identified, including tensions between the two nations at the end of World War II, the ideological conflict between both the United States and the Soviet Union, the emergence of nuclear weapons, and the fear of communism in the United States.
