US of A has already created enemies.
See 9/11 for an example of "nobody is going to attack us" being false.
Could the nation slowly step back and generation-by-generation shed their national reputation such that they have no enemies? Maybe.
But that would take a while (generations) without any guarantee and is kind of the opposite of what has happened recently.

This is basically what the UK did after WWII. We’d have to be honest that a fall in relative living standards would probably accompany such a move. (Counterpoint: the Nordic countries.)
