American socialist revolutionaries are terrified of there finally being a power vacuum and a crisis to exploit.

Because we have zero chance of filling it. None. It can't happen. If you rip apart America you're left with a bunch of insane reactionary warlords with piles of nukes.

End up with some crazy evangelical theocrat who decides they were chosen by god to bring on the apocalypse or setup a white christian ethnostate that makes Saudi Arabia look good.
