I just want to mention that there’s a series of difficulties:

• practically, a good 20% - 30% are still backing trump, especially among “republicans for life”. It would be easy to topple a government if 99% of the population despised it, but if 20% back it, it’s difficult because it can retract and re-collect strength.
• normally, conflicts are decided by who can stay solvent longer, i.e. who has more money. normally, that would be blue states, but if trump can just print money through the federal reserve, then that kinda makes that point more questionable. blue states kinda would have to start using their own currency, or some foreign currency like the canadian dollar or the mexican pesos, to be fiscally independent from washington. that’s a logistic challenge to pull off so quickly. but it can be done.
• then there’s a shitload of cultural issues. the vietnam kicked the american’s butt because they were fierce and willing to die for their cause, because they were willing to die for their community. america doesn’t have communities like that, america is very atomistic, i.e. everybody fights for themselves. establishing a good sense of community is a whole lot of work and takes a long time. i don’t see it happening overnight.
