The Strengthening Nuclear Security Implementation initiative: evolution, status and next steps

The "Strengthening Nuclear Security Implementation" initiative broke new ground at the 2014 Nuclear Security Summit in the effort to harmonize and strengthen the global nuclear security regime. This report discusses the significance of the initiative, the importance of expanding its signatories, and the need to demonstrate its implementation. The report benefits from the insights and experience of Nuclear Security Governance Expert Group (NSGEG) members and draws upon major themes of discussion at NSGEG workshops in Vienna, Austria (2014) and Washington, D.C. (2015). These workshops were sponsored by the Asan Institute for Policy Studies, Partnership for Global Security, and the Stanley Foundation as part of a continuing discussion on nuclear security governance.
