2016 - 2020 was a pretty good time for the world, except for covid. No new wars, Abraham peace accords, plans to pull out of Afghanistan properly, making peace with North Korea, keeping sanctions and restricting funding for Iran.
I'm not American, but objectively it's hard to see what the big deal was, democracy did no die, WW3 did not happen, economy was booming. I guess if all you do is watch CNN all day, and go along with the agenda.
