  On April 2 in Lausanne, Switzerland, Iran the P5+1 (China, France, Germany, Russia, the United Kingdom, and the United States) reached a breakthrough on the parameters of an agreement to verifiably roll back and constrain Iran’s nuclear program. As 30 leading nonproliferation specialists detailed in an April 6 statement, a comprehensive agreement based on these parameters would be a net win for nonproliferation and international security. Yet, a concern repeatedly voiced against the developing deal, which would allow for a limited Iranian uranium-enrichment program, is that it will…

The Preparatory Commission for the Comprehensive Test Ban Treaty Organization (CTBTO) carried out their second integrated field exercise (IFE14) in Jordan’s Dead Sea region from Nov. 3 to Dec. 9, 2014. The field exercise was designed to replicate a scenario in which a country (in this case, the fictional “Maridia”) has been accused of conducting a nuclear test and now the CTBTO must find evidence to either repudiate or validate this claim and find the specific nuclear test explosion site. Once the Comprehensive Test Ban Treaty (CTBT) enters into force, any state party will have the right to…

At the mid-point in the month-long 2015 Nuclear Nonproliferation Treaty (NPT) Review Conference in New York, there is growing frustration about the new approach being pursued by Egyptian Foreign Minister Sameh Shoukry and other Arab League states on the goal of convening a conference to discuss a weapons of mass destruction (WMD) free-zone in the Middle East. A proposal engineered and advanced by Egypt would give the UN Secretary General the sole responsibility to hold a conference on establishing such a zone. But this proposal, which would cut out Finnish diplomat Jaako Laajava—the…

The National Nuclear Security Administration (NNSA) recently led an experiment designed to improve the United States’ ability to detect underground nuclear explosions using conventional and advanced detection technology. This experiment was the fourth in a series of experiments conducted since 2011. The experiment tested many detection tools, such as: high-resolution accelerometers, infrasound, seismic, explosive performance, electromagnetic, ground-based LIDAR (light detection and ranging), digital photogrammetry data, and satellite-based interferometric synthetic aperture radar (InSAR…

As 190 countries meet in New York this month to discuss the implementation of the nuclear Nonproliferation Treaty (NPT), a number of steps can be taken to accelerate the pace of disarmament and ensure that the world’s most dangerous weapon do not spread. The NPT, which entered into force in March of 1970, is the most comprehensive nuclear arms control agreement in the world. The NPT divides the 190 party members into two groups. Five countries are recognized in the NPT as nuclear-weapon states and have committed to disarm all existing nuclear weapons. These states are the United States,…
