The origins of Cold War competition between the U.S. and the Soviet Union can be traced back to the end of World War II. The two countries had been allies during the war, but their relationship began to deteriorate as soon as the war ended. The main sources of tension between the U.S. and the Soviet Union were ideological differences, with the U.S. promoting democracy and capitalism, and the Soviet Union advocating for communism.

The U.S. was concerned about the spread of communism, particularly in Eastern Europe where the Soviet Union had established communist governments. The U.S. also feared Soviet expansionism and aggression, as exemplified by the Soviet blockade of Berlin in 1948. The Soviet Union, on the other hand, viewed the U.S. as a capitalist imperialist power seeking to dominate the world.

The Cold War competition between the U.S. and the Soviet Union intensified as both countries sought to expand their spheres of influence and ideological influence around the world. This competition played out in various ways, such as the arms race, the space race, and proxy wars in places like Korea and Vietnam.

Overall, the origins of Cold War competition between the U.S. and the Soviet Union can be attributed to their differing ideologies, conflicting interests, and mutual distrust that emerged at the end of World War II.
