It aims to create a registry of arms owners in USA that would be shareable with other signatory countries.  If the other countries feel USA isn't keeping up with world norms in regard to arms, we could be sanctioned on trade as a result.  It gives way too much info about gun owners and ownership to other countries that don't necessarily have our best interest at heart.  It's globalist disarmament bullshit.  Our 2A rights our not the rest of the world's business.
