I salute the Arms Control Association … for its keen vision of the goals ahead and for its many efforts to identify and to promote practical measures that are so vitally needed to achieve them. -

Defense Bill Restricts CTBTO Funding
Share this

The most recent annual National Defense Authorization Act, signed into law on Dec. 12, includes language restricting U.S. financial contributions to the Comprehensive Test Ban Treaty Organization (CTBTO), except for funds related to the International Monitoring System, which detects nuclear test explosions. The CTBTO is the international organization that promotes the Comprehensive Test Ban Treaty in advance of its entry into force and builds up its verification regime.

Although not included in the Senate bill, the measure was incorporated into the conference bill, which passed the House on Nov. 14 and the Senate two days later.

The bill also includes an assertion that UN Security Council Resolution 2310, passed in September 2016, calling for the treaty’s early entry into force and the continuation of nuclear testing moratoria does not “obligate the United States nor does it impose an obligation” to refrain from actions that would run counter to the treaty. The amendment’s supporters argue that the United States should not be bound by or contribute financially to a treaty the Senate has not ratified. Opponents of the provision contend that it could signal a weakened U.S. commitment to the global moratoria on nuclear testing and undercut support for the treaty.—ALICIA SANDERS-ZAKRE
