At this point I'm a little worried about Trump's prospects for the midterms
Without a strong mandate he won't be able to do crazy shit and bring about the collapse of US hegemony
But if MAGA gets annihilated at the midterms, Trump will spend the next two years preparing and just cancel all future elections when his term is about to expire.
It’s basically what he has been preparing for since taking office anyways, only defeat at the midterms will make it that much more unlikely he will TACO this time, as if he does and the Democrats come into power again, the will crucify him, potentially literally, so he will have nothing to loose and everything to gain to become God Emperor.
The most likely route he will take will be to engineer or force a crisis so monumental and existential that the majority of Americans won’t seriously question his suspension of elections until after the crisis has been dealt with. The two most likely and obvious routes are either massive foreign war (aka WWIII) or Civil War 2.0 in the states.
Personally I think Civil War 2.0 is slightly more likely, as Chinese hard power makes a world war unacceptably risky for Trump, since it’s extremely unlikely America can win a conventional hot war against China (going nuclear is pointless as then everyone dies and Trump doesn’t want to die). His biggest enemies are domestic in any case, so it makes perfect sense for him to go scorched Earth with his domestic enemies and wipe them out once and for all to consolidate his power forever at home.
Ironically, for a major foreign war, USA vs the EU is actually just as, if not more likely than NATO vs China and Russia. Since the USA can actually expect to handily curbstomp the rest of NATO, and gobble up Canada into the bargain.
So it’s not out of the question for Trump to split Europe with the Russians like it’s one giant Czechoslovak and sell out Japan, SK and Australia to China while America re-focuses on securing the Americas and eradicating its domestic enemies and turns America into a new giant North Korea.
