How did US defeat the World Superpower?

Answer:
In the World War 2 period there was no one power that could be called "the World Superpower" so the US did not defeat it.

At present some call the US "the World Superpower." Whether that is a valid description or not is a matter of opinion, but even if true it is still not possible for the US to defeat itself so the US has never defeated "the World Superpower."
