Answer:
the Cold War.
Explanation:
The Cold War period was the result of the ideological, economic, and political breach that was created between the winners of World War II, mostly represented by the Soviet Union —the eastern bloc— and the free market economy of the USA —the western bloc. This confrontation led these two nations to an arms race and a form of interventionist politics all around the world, with each nation claiming superiority and control over different key geopolitical areas of the world. Some of these confrontations carry consequences even to this day.
