I don't think we are anywhere near civil war. I believe we might be on the verge of state violence against protestors.
You'll know we're on the brink of civil war when there is open combat between militia or national guard and the military and the military doesn't instantly put them down.
A military coup might be slightly more likely or at least doable. But I'm not sure there is anyone left in charge who might lead that. Plus, it is by definition treason, and no soldier takes that lightly. And the resultant government might not be what one might want.
I hate to say this, but the US isn't going to pull the rest of the world out of this mess. The way forward is through. Or wait for cholesterol to do its job and hold your breath for real elections this fall.
