I mean it's quite the tradition for the USA to help authoritarian leaders if it means more capital for their industry and banks. Saudi Arabia and Qatar have been its allies, while it demonizes Islam at home. It's currently helping Israel genocide Palestinians since forever. It invaded Afghanistan to destroy Taliban, only to hand it over to Taliban 20 years later.

So many examples.

So yeah, It's really not unique to Trump.
