Answer:
After the second world war, United States together Western European nations had ideological differences between the Asian continent countries and few nations of Eastern Europe based on capitalism and communism. Capitalism ideologies advocated for citizens' free expression to acquire wealth, trade freely, and participate in anything without the influence of the Government. In contrast, communisms practiced by the nations within the Soviet Union adopted policies that embraced socialism, public ownership of resources that were aimed at eliminating any social classes, and involving Government to control everyone in both economic and socio-political perspectives.
British prime minister Churchill introduced the cold war when he made his speech commonly referred to as the "iron curtain," which drew a line to separate Western European countries (Capitalists) and Eastern European Countries (Communist). The United States supported capitalism ideologies which created a conflict with the communists from the Soviet Union between 1946 to 1990. Most countries in the Asian Continent, such as Russia, Vietnam, Korea, and any other Asian country which had significant wars with the US in World War II, were pro-communist and differed with capitalism that America campaigned. Communism had good policies that caused grievous friction with capitalism was the essence of dictatorship, which communist practiced among themselves. Western countries and the Soviet bloc developed conflict to comprise political relations due to the ideologies that resulted in democracy among the capitalist and dictatorship among the communists.
