I don't believe that the vast majority of our armed services would fire on Americans. I do believe that the Blue Hats of NATO would have no problem doing so.
The "Blue Hats" belong to the UN not NATO. And since the UN has no standing army it's usually just shitty 3rd World Troops. Do any on you guys check and see if a kook thread for what ever look theory your about to post already exsist? Because this one already does. It's also made up garbage.
