How did the end of World War 2 politically affect both the US and the Soviet Union?

The end of World War II marked the beginning of a significant geopolitical shift, with the United States emerging as a global superpower, promoting democracy and capitalism. In contrast, the Soviet Union solidified its influence over Eastern Europe, advocating for communism and establishing satellite states. This ideological divide led to the Cold War, characterized by political tension, military rivalry, and competing spheres of influence between the two nations. Both powers sought to expand their ideologies globally, leading to conflicts and proxy wars in various regions.
