Answer:
Who was the Cold War between? Between 1946 and 1991 the United States, the Soviet Union, and their allies were locked in a long, tense conflict known as the Cold War. Though the parties were technically at peace, the period was characterized by an aggressive arms race, proxy wars, and ideological bids for world dominance.
Why do you believe it is called the Cold War? The Cold War got its name because both sides were afraid of fighting each other directly. In a "hot war," nuclear weapons might destroy everything. So, instead, both sides fought each other indirectly.
