Maybe this is too fedposty (and let me know if it is), but I've been thinking about this a lot, especially with how things are going in Iran. It seems like modern warfare is basically just "my drones strike your drones", and if either side has drones free to not strike other drones, they can instantly kill whoever they like. With this in mind, is it even really possible for a revolution in the US to escalate into a civil war without simply being air-superiority'd into oblivion with modern sensors? Is guerilla war viable anymore? The main counterpoint I can think of to this possibility is that the US military is A: incompetent and B: mostly a colonial garrison force, but I don't know.

(And yeah, I know a revolution in the US would have a whole laundry list of prerequisites and is significantly hindered by the fact it can't be tied with anti-imperial nationalism. I'm talking strictly in terms of if it actually happened.)
