This course is devoted to a simulation of the second NPT Preparatory Committee (PrepCom) meeting following the 2015 NPT Review Conference. This PrepCom will be held in Geneva in spring 2018 and will constitute the second two-week session of the 2020 NPT review process cycle. It will involve multilateral negotiations on the implementation of the NPT, with special reference to issues of nuclear disarmament, nonproliferation, and peaceful uses of nuclear energy. Based on the outcome of the 2015 Review Conference and the July 2017 Treaty on the Prohibition of Nuclear Weapons, one would expect major debates at the 2018 PrepCom on the subjects of nuclear disarmament (and especially the impact of the “Ban Treaty” on the NPT), nuclear risk reduction, further reductions in all types of nuclear weapons, creation of additional nuclear-weapon-free zones (especially in the Middle East), the DPRK and other regional nuclear threats, negative security assurances, nonproliferation compliance, international safeguards, nuclear terrorism, peaceful nuclear uses, and provisions for withdrawal from the Treaty.
