Explanation:

The Cold War began following World war II when the relation between the United States and Soviet Russia remained tense. The tense rose as the Soviet Union began to expand its territories and communism in neighboring countries. The Cold war started when America developed an atomic bomb to show its dominance to the world because of its destruction. The Soviet Union became the second nation to develop a nuclear weapon to challenge the United States. Both the countries emerged as a superpower but remained different because of the political ideas on communism and democracy.
