Lets just say hypothetically USA stopped all the perceived negative political and military policies that so much of the world now condemns us for. How long would it take for USA to be regain favorable opinions from the many European nations that now so loathe us? Could you ever love a USA again? Or is something that will only change in a generation when the young ones did not live through it and only see the "perfect" USA. Much like how Germany/Japan has been forgiven for there past transgressions (it did not happen overnight).
