America and Soviet Union which were united leaving Fascism during the second world war were again separated after the war. America became the new economic nation and led capitalists. Soviet Union formed socioeconomic growth of the nations.
A result of cold war was the differences in the ideologies and diplomatic confrontation of two regions which were enemies. They planned to help their own regions. When the whole world decided to be a part of any powerful region the countries in Asia arid Africa stayed free. They were called third world nations. They feared that the powerful regions may lead for threats and use of dangerous weapons may lead for a 3rd world war. Gradually non-alignment was formed.
