The Fight between US and USSR during the Cold War Period:

1.Relations between East and West were never cordial. Short of going to war directly, the two camps indulged constantly in political and military competition. This state of affairs was widely called as the "Cold War". The Cold War was marked by a great deal of competition in forming military alliances, viz. the North Atlantic Treaty Organization (NATO) and the Warsaw Treaty Organization and the arms race through sophistication of nuclear weapons.

2. The United States and the Soviet Union stood out as two opposite poles around which, to begin with, the European politics revolved. While the countries of Western Europe joined hands with the United States and called themselves the "Free World", countries of Eastern Europe became part of the Socialist camp led by the Soviet Union. These two leading countries of rival camps were clubbed under the exclusive, new category of "superpowers".

3. Soon the two Cold War rivals grudgingly acknowledged that each could destroy the other in a nuclear confrontation many times over. In the face of such dangers, the bipolar relations assumed new dimensions. On the one hand, the two camps got involved in local conflicts in West Asia, South Asia, East Asia, Central America and southern Africa.

4. As a result a good deal of military "aid" flowed to the newly found or prospective allies. At the same time, attempts to stop the spread of nuclear weapons and deny their access to other countries started in 1960s.
