How would life be different without world war 2?

Well since America won the war and restored almost everything to the way it used be life would only be a only a little different. Things that would be different are 1. there would be no Soviet Union which means there would be no such thing as Communism and China wouldn't be Communists today and America might not be 13 trillion dollars of debt. 2. There wouldn't of been the Korean and Vietnam Wars, and you can figure it out from there.
