What do you mean by "the US defeated Nazi Germany"?
As I understand it the US was preoccupied with Japan until the USSR had Berlin within reach. US racial policy being an inspiration for european fascists, like Hitler, kind of makes the affiliation with nazis both in the US and West Germany (and NATO) easier to understand than the USSR keeping some nazis in important positions on their side.
