The greatest superpower at the end of World War II was the United States, although it should be noted that the Soviet Union was seen as another great superpower as well.
I believe that the answer is that the use of nuclear weapons ended the war much faster than Stalin had anticipated. Stalin wanted to enter the war in the pacific, however the use of nuclear weapons crippled the Japanese, forcing them to surrender.

Eventually this bad blood lead to the Cold War as things got more tense between the two. Hope this helped!
