Catastrophism is native to American politics. How, exactly, you live in a globalist world without forming an opinion on the matter is a study of sociopaths for someone else. There is no post-WWII America without the myth of catastrophe and salvation via nuclear war. We built this nation, and set the global status-quo, on the back of a global catastrophe. Ignoring that fact doesn't make you a better historian, it makes you blind.
Maybe those Bluesky users are just repeating the past 150 years of anthropological research that pertains to postmodern human politics. This Nate Silver guy would probably cream his shorts if he read Hegel.
