The USA has never been defeated. It's never been taken over by force and forced to submit to a foreign power. War getting a little too expensive or politically unpopular for their tastes is not really a loss, and it implies nothing about their true capabilities.
It's their relentless deindustrialization that will eventually do them in. The USA's industrial output back in WWII was staggering, its enemies had little hope of victory given the sheer number of materiel that would eventually get deployed. Since then they've been voluntarily giving up much of that industrial advantage out of greed.
