In broad strokes, this sounds parallel to what has been happening nationally.
The US gov'ts keep passing laws to stop violence and trafficking of guns. These laws negatively affect the good citizens while the criminals ignore them.
Now the UN is trying to do the same thing on a global level which puts the U.S. on the other end of the argument-where we are signing this treaty while sending arms at the very same time to Syria.
It will be interesting to see how the very same people who creatively try to kill the 2nd amendment will justify future actions when they feel the need supply another country with arms without a background check nor care where those weapons end up.
(ironically, this is a global version of the 'gun show' loophole they have twisted except it is a little worse
, no background check, it is using tax dollars that came out of our paychecks and it's not even face to face).
Who knows, maybe they will create a playbook the NRA can use.
