That's not unusual for Americans, though. Bush, Clinton, Reagan, Nixon... Americans have been putting up turds to the Oval Office since President Kennedy's term abruptly ended.
Turns out Kennedy too was more of a turd than most people suspected at the time. Not in the same league with your list, but still a real mess once you know enough about him.

All of those guys were way more respected than Trump. And of the rest, all of the others not Bush jr were way more respected than Bush jr.
The current period IS very unusual for how badly our reputation has fallen. Although you could also say America's reputation around the world was unusually high from 1945-2000.
