James Mason,
Would you rather the terrorists are killed here in the US or over there ?
Actually, I think the way our country is going that we may end up with our troops fighting a in a revolution as well as a civil war here. 
Things started to get bad here long before Trump was sworn in as president. I remember my son being trained as a Marine in urban warfare. That was back in '98 and '99. Urban warfare included training them not to react to name calling, being spit on, cursed at, and having rocks thrown at them. In one of the training my son "got" to p,as the role of one of the protesters and he knew how to push the buttons on the Marines. He ended up with a broken arm!  They also trained in fighting in "cities" which came in handy later on in Iraq. But I often think about the training getting them ready to rout out revolutionaries or Civil wat fighters.......maybe both.  His training later helped him to save a few of his fellow Marines lives and how to survive the cemetery battle.
