That is a scary possibility. That it'll just turn into a long bloody standstill with the right being too divided to actually pose a serious threat but the left unable to really get rid of them either. While I do think the right would have a moderately easy time winning, what I'm also afraid of is that the right will go too far in the other direction and the new government we get is oppressive in some other way.
True. I however meant something else. War is not good. It's bad, very very bad. But sometimes it can be necessary. A Civil War however? That's kinda like cutting off your Nose to spite your face.
Let's just run with the idea of a right-wing vs left-wing civil war. So, what exactly would the goal be? The left's strongest points are concentrated on either end of the Landmass whilst dotting specific, often high population areas in the rest of the country. So, I'd say in either scenario, some kind of splitting off solution seems less then ideal for either side. If the Goal is essentially to subject them to your political will...how is that supposed to work? The US is pretty fucking huge and we are talking about what would have just been a literal enemy in War, even if you win, they aren't going to just cooperate, not matter who "they" is. So...what remains, mass political culling perhaps. So, basically complete destruction or at least to the point that any survivors would either be demoralized or few enough in Number to be suppressed, neither option seems plausible, but either way would obviously require atrocities. And considering how much effect a US Civil War would have on the World at large, I wouldn't expect that shit to stay civil if I were some would-be fighter. There would definitely be intervention.
So, from where I am standing there is nothing to be gained and plenty to lose.
