The Cold War drew on the international relations of 1947 to 1991 through categorizing the world into two main sets: the United States as the head of capitalism and the Soviet Union as the head of communism. Countries on one side, which characterized the world politics creating a long time ideological gap.
This was divided by military alliances. NATO (i. e. the U.S.) opposed the Soviet influence, and the Warsaw pact joined Eastern European countries in the USSR. All these alliances formed organized defense systems and increased tensions which continued to drive the diplomatic approaches and world decision-making over decades.
The Cold war stimulated the arms race, particularly the nuclear ones. The two superpowers invested so much on military technology in order to dominate. This was a competition that made the world more insecure and forced countries to choose sides, which impacted foreign policies and preferences of nations in the context of international security.
Proxy wars were a key feature. Superpower rivalry was evident in conflicts in Korea, Vietnam and Afghanistan. The U.S and USSR never fought directly, but helped conflicting sides, demonstrating how the Cold War affected the domestic conflicts in the regions and reinforced the ideological boundaries in the world.
The power of economies and politics was also growing. The U.S. encouraged the ideas of capitalism and democratization with such programs as the Marshall plan, and the USSR supported the idea of the government of socialism. These plans influenced the world in terms of business, regulations and rivalry, supporting attacks and restraining counter-influence.
Conclusion
The Cold War order very simply organized international relations by division into ideologies, military alliances, armament propaganda, proxy wars, and economic weapons, a situation which had long-term effects into the politics of the world after 1991.
