Allow me to let you in on a little secret; 'Arm USA' doesn't care about the U.N., nefarious plot or not. This is just marketing 101: make the customer feel like buying your product means something bigger. In the early in the century, the tobacco companies told women that it was an act of protest and suffrage to smoke. Now would someone like to explain to me the link between cigarettes and getting the right to vote?
Buy a gun if you feel you need one, not because of marketing hype.
