So I think that all in all this current deal is a big bag of nothing. The reason to worry about the defense of the country isn't because this agreement would theoretically make it harder to defend. Rather, the problem is that Obama doesn't seem willing to defend it, agreement or no agreement.
Just because you have a CCW, pack a .45, and shoot perfect scores doesn't mean that you won't end up dead in a dark parking garage with your unfired pistol in your hand.
Word. Anyone with any personal defense training will tell you your most important weapon is between your ears. If you're not willing to defend yourself, right now, the rest doesn't matter.
