The international community considers the deliberate use of chemical, biological, radiological, or nuclear devices as uniquely abhorrent. The fear of these weapons is so profound that, on the one hand, it spawned an entirely new concept of conflict and conflict management in the form of deterrence. On the other hand, it also led to the establishment of a robust international architecture of laws, treaties, agreements, and norms designed to prevent the proliferation and use of these weapons. Despite these efforts, there is concern across the international community about the spread and limited use of WMD. The International Security Program, Project on Nuclear Issues, and Proliferation Prevention Program conduct timely research and analysis on countering the spread of weapons of mass destruction from the continued use of chemical weapons in Syria to the threat posed by non-state actors to the effort to prevent further nuclear proliferation.
