Americans may be misleading themselves if they think that all the damage Trump has done will suddenly be undone once he is gone. Most people outside the US see Trump as holding up a mirror to what America really is that was previously cloaked in some level of diplomacy so it wasn’t so readily shown to the world. Plus the US used to have the money to buy goodwill but Trump is doing his best to bankrupt the company (country) while lining his own pockets, the only skill in which he has prior demonstrated ability.
