I think the bulk will still have a hard time killing their fellow Americans. Back when there was a Soviet Union, they wouldn't have the SSR's soldiers keep their own people in line. Bulgarian soldiers would be sent to Hungary, Hungary solders to Poland, Polish soldiers to one of the "stan's" and so forth. Is California so different culturally that they would kill their fellow citizens in Alabama? Probably not. That is where the UN "peacekeepers" come in. They'll have no problem rounding up Americans and having them shot. So do what I'll be doing and kill them first. Yeah, I said that. As far as I am concerned, those blue beret bastards are an invasion force, I don't care if any one in government invited them in. Their are fair game.
