I worry about the same thing. Trump and Reagan were two in a million. I believe the hot civil war is only being postponed for 6 years.
There is no Civil War, only Civil slaughter since the military if genuinely oppressive would have all the big and powerful weapons, not to mention trained equipped killers. Plus they could just either set up or arrest plenty of people on trumped up charges and even The majority of Freepera would go along with punishing the criminals.
