So, lets say we get to August or some summer month, and 4,000,000 people are protesting right out front the white house.
Do they send in the tanks? Do they kill 1,000,000 people? Would republican civilians see empathy for the dead americans who were democrats? Or would it unite the nation like 9/11 did, except this time against the government?


Yep, there is no organization capable of staging armed opposition to the government. A series of mass shootings and maybe some explosives is all we are going to get.
Given the number of incidents, I wouldn’t be shocked if historians decide later we are already living through it. Political assasinations in Minnesota, the attempted murder of pelosi’s husband, attempted trump shooter, charkie Kirk, the car bomb in Memphis that didn’t go off a few years ago. The United Healthcare CEO hit. Attempted kidnapping of Gretchen Whitmer.
There is plenty of violence to go around, but nothing that would rise to civil war.
I have imagined a scenario where a debt crisis degrades the capacity of the federal government and polarization leaves citizens and national guard more loyal to their state than the federal government, but we are a long way away from that.
