You can’t have it both ways. You can’t close all your embassies, stop giving foreign aid to “shithole countries”, say, incendiary things about nonwhite immigration, ban Muslims from visiting, and then expect non-white countries to think highly of your greedy, racist, xenophobic attitudes.
Trump going around the world failing to honour treaties and agreements didn’t improve relations either. It simply convinced the world that the USA cannot be trusted to live up to the agreements.
Biden has re-established your leadership of NATO, for now, but as Macron said “For how long?” If Trump is elected, he’ll pull out of NATO, ceding European power to Putin.
