How did the problems that arose at the Potsdam and Yalta conferences foreshadow Cold War conflicts between the United States and the Soviet Union?

The main conflict was on 17 July 1945, Josef Stalin, Harry S. Truman, and Winston S. Churchill (who was replaced on 28 July by Clement Attlee) met for eleven days at Potsdam near Berlin. They faced two related issues: ending the war against Japan and restructuring Germany and Eastern Europe.

Explanation:

While a number of important agreements were reached at the conference, tensions over European issues—particularly the fate of Poland—foreshadowed the crumbling of the Grand Alliance that had developed between the United States, Great Britain, and the Soviet Union during World War II and hinted at the Cold War to come.
