This may be true, but which American citizens will they be firing upon? Their oath is to the Constitution, and I doubt a lot of them would come down on the side of HRC. The military would either side with us, or just sit this one out.
Perhaps. Obama has had 8 years to change the structure of the military. The culture is not what it was. There will be some who will sit it out, others will follow orders, a few may rebel in the name of the Constitution. It will, by any measure, be a disaster. I have friends who are special forces. They do not believe a citizens army can stand against the military.
