Matt, this has been a concern to me. Everyone says not to worry, the Senate would never ratify it. First, I don't believe that. Unless we strong arm them, they might. Especially since the shift in power. But other countries might go along with this and we will have a de facto partial embargo. Since we have allowed so many firearms comapanies to fall into foreign hands, it might be a problem. Tarus, Baretta, Glock, Sig, HK,... atleast Smith&Wesson is no longer British and most of our long guns are made here by US companies.
The biggest problem with the UN thing is that the US is the obvious target. Even if the US does not go along with it, the move is designed to make us look like the bad guy and the gun nuts and turn world opinion against us. This will give the antis more leverage legislatively.
The good news is that the conference was originally planned for Switzerland and the Swiss told them they couldn't have it there!
