I've been hearing libs (and chuds too) say this for nearly a decade now and I'm sick of it. Trump doesn't control the military, if he tried to go rogue he'd just get arrested. Or just ignored. How many of the corporate interests that make up much of the ruling class today would benefit from a civil war? They've got a fairly sweet deal going on. I could see the Fed gov fall apart domestically, lose it's ability to respond to disasters, and see state govs also abandon that responsibility, slowly leading to warlordism breaking out, but that's really got very little to do with Donald Trump.
