This edited collection presents an innovative approach to global security regimes. Employing both conceptual and empirical studies, the volume examines three empirically-oriented sets of cases: weapons of mass destruction, humanitarian disarmament and unconventional threats. The book combines interrogations of the most prominent prohibition/regulatory regimes while covering WMDs, humanitarian issues and other agendas such as drugs, endangered species and cyber security. It will be of interest to academics and researchers in International Relations and Security Studies.
