OK, I searched (USMB search function is a joke) for discussion on this as POTUS erased this ill advised plan in late April. The UN has no authority over our Constitution and just like that, POTUS eliminated another Obama anti-American destructive agenda

INDIANAPOLIS — In a speech to National Rifle Association members on Friday that was part political rally and part pep talk, President Trump called himself a champion of gun rights. Then he proved it, whipping out a pen onstage to sign a letter that would effectively cease America’s involvement in an arms treaty designed to regulate the international sale of conventional weapons
Trump Pulls Out of Arms Treaty During Speech at N.R.A. Convention
The fact is that the UN Small Arms Treaty is the best example of far right wing propaganda. The Congressional Research Service explains it best.
"The ATT regulates trade in conventional weapons between and among countries. It does not affect sales or trade in weapons among private citizens within a country. The treaty obligates states parties engaged in the international arms trade to establish national control systems to review, authorize, and document the import, export, brokerage, transit, and transshipment of conventional weapons, their parts, and ammunition."

This is Trump appealing to far right radicals and shows how far right the NRA has become. The NRA is likely to be a millstone around Republicans' necks.
