How did differing post-war visions for Europe increase tensions between the Allies? What actions deepened these tensions

The main allies: U.S., U.K., and U.S.S.R (Excluding France because at this point they were actually being under consideration to be treated as a "Conquored" nation because of the "Vichy France" state they were in established by germany)

Explanation:

Differing post war vision increased tension because the U.S.S.R was spreading communism amongst eastern europe which was (unsurprisingly) seen as a threat by the United States and the rest of the western hemisphere who believed in capitalism mainly. These tensions would be deepened by the creation of the U.S.S.R formed "Warsaw Pact" and the west formed "NATO" and both sides would fund countries in ongoing civil wars, because usually the civil wars would have 2 sides fighting: Communists/Left Wingers and Capitalist/Nationalists/Right Wingers, this would start as the cold war with many nations in a state of civil war being funded by both sides, some of which listed below:

Vietnam

Nicaragua

Korea
