Last week, the United States announced its support for U.N. efforts to develop a new treaty regulating international trade in conventional arms. The terms are still far from settled, but draft provisions from a U.N. review conference last summer provide a rough guide on how the treaty might work. In this post, I want to highlight some of the key provisions and then explain a likely practical hurdle to U.S. ratification. In a subsequent post, I’ll address a Second Amendment objection raised by treaty critics.

The latest draft suggests that the treaty would have four basic dimensions. First, it would establish a limited number of categorically prohibited international transfers. These include transfers in violation of a measure adopted by the U.N. Security Council pursuant to the Council’s peacekeeping authority; transfers in violation of other international obligations; and transfers made for the purpose of facilitating genocide, crimes against humanity, or certain categories of war crimes.

Second, the treaty would limit the power of states to export conventional arms by requiring assessments on whether proposed exports would contribute to or undermine peace and security. Mandatory considerations would include whether the arms could be used to commit a serious violation of international humanitarian law, human rights law, or an offense under international treaties relating to terrorism. In the event of an “overriding risk” of one of these consequences, the treaty would prohibit the exporting state from authorizing the transfer. The treaty would also require exporting states to “consider taking feasible measures” to make sure that the arms are not diverted to the illicit market, used to commit gender-based violence, or used by transnational organized crime.
