Leading nation-states isn’t a black and white thing, there’s always going to be decisions that have to be made based on the information those leaders have at that moment and sometimes those decisions have negative consequences.
However with that being said there has never been an American president that was an outright corrupt traitor like Trump was, he was purely out for himself and selling the rest of us out to the probably not even the highest bidder, probably more the bidder that was the best at sucking up to Trump or promising him the best stuff.
