Secretary of State John Kerry on Wednesday signed a controversial U.N. treaty on arms regulation, riling U.S. lawmakers who vow the Senate will not ratify the agreement.  As he signed the document, Kerry called the treaty a “significant step” in addressing illegal gun sales, while claiming it would also protect gun rights. “This is about keeping weapons out of the hands of terrorists and rogue actors. This is about reducing the risk of international transfers of conventional arms that will be used to carry out the world’s worst crimes. This is about keeping Americans safe and keeping America strong,” he said. “This treaty will not diminish anyone’s freedom. In fact, the treaty recognizes the freedom of both individuals and states to obtain, possess, and use arms for legitimate purposes.” 

U.S. lawmakers, though, have long claimed the treaty could lead to new gun control measures. They note the U.S. Senate has final say on whether to approve the agreement.  Sen. Bob Corker, R-Tenn., in a letter to President Obama, urged his administration not to take any action to implement the treaty without the consent of the Senate.  He claimed the treaty raises “fundamental issues” concerning “individual rights protected by the Second Amendment of the United States Constitution.” 

The National Rifle Association blasted the plan, claiming it would impose an “invasive registration scheme” by requiring importing countries to give exporting countries information on “end users.”  “The Obama administration is once again demonstrating its contempt for our fundamental, individual Right to Keep and Bear Arms,” Chris Cox, executive director of the NRA’s Institute for Legislative Action, said in a statement. “These are blatant attacks on the constitutional rights and liberties of every law-abiding American. The NRA will continue to fight this assault on our fundamental freedom.” 

Sen. Jim Inhofe, R-Okla., one of the most vocal opponents of the treaty, also sent a letter to Kerry declaring the treaty “dead in the water,” since a majority of senators has gone on record against the agreement. “The administration is wasting precious time trying to sign away our laws to the global community and unelected U.N. bureaucrats,” he wrote.  Kerry, who is in New York attending the U.N. General Assembly session, announced earlier this year that the administration planned to sign the treaty.

The treaty would require countries that ratify it to establish national regulations to control the transfer of conventional arms and components and to regulate arms brokers, but it will not explicitly control the domestic use of weapons in any country.  Still, gun-rights supporters on Capitol Hill warn the treaty could be used as the basis for additional gun regulations inside the U.S. and have threatened not to ratify.

Over the summer, 130 members of Congress signed a letter to President Obama and Kerry urging them to reject the measure for this and other reasons.

The chance of adoption by the U.S. is slim. A two-thirds majority would be needed in the Senate to ratify. 

What impact the treaty will have in curbing the estimated $60 billion global arms trade remains to be seen. The U.N. treaty will take effect after 50 countries ratify it, and a lot will depend on which ones ratify and which ones don’t, and how stringently it is implemented.

The Control Arms Coalition, which includes hundreds of non-governmental organizations in more than 100 countries that promoted an Arms Trade Treaty, has said it expects many of the world’s top arms exporters — including Britain, Germany and France — to sign alongside emerging exporters such as Brazil and Mexico. It said the United States is expected to sign later this year. The coalition notes that more than 500,000 people are killed by armed violence every year and predicted that “history will be made” when many U.N. members sign the treaty, which it says is designed “to protect millions living in daily fear of armed violence and at risk of rape, assault, displacement and death.” 

Many violence-wracked countries, including Congo and South Sudan, are also expected to sign. The coalition said their signature — and ratification — will make it more difficult for illicit arms to cross borders. The treaty covers battle tanks, armored combat vehicles, large-caliber artillery systems, combat aircraft, attack helicopters, warships, missiles and missile launchers, and small arms and light weapons. It prohibits states that ratify it from transferring conventional weapons if they violate arms embargoes or if they promote acts of genocide, crimes against humanity or war crimes. The treaty also prohibits the export of conventional arms if they could be used in attacks on civilians or civilian buildings such as schools and hospitals.

In addition, the treaty requires countries to take measures to prevent the diversion of conventional weapons to the illicit market. This is among the provisions that gun-rights supporters in Congress are concerned about.
