Designating North Korean Nuclear Weapons as Proliferation Risks: A Proposal for Forestalling Major Power Conflicts in the Event of North Korea's Internal Collapse

A potential North Korean internal collapse would pose enormous challenges to South Korea, to include the risk of catalyzing a major U.S.-China crisis. Creative diplomacy by Seoul, however, could lay the groundwork for all three states to designate North Korea's nuclear weapons as "proliferation risks" within a notional future crisis, providing common ground for Washington and Beijing--who have worked together on key nonproliferation initiatives in the past--to tacitly cooperate on (or at least de-conflict) efforts to address the security threats posed by Pyongyang's nuclear arsenal within a dynamic internal conflict environment.

March Issue, Arms Control Today: "Deter and Downsize: A Paradigm Shift for Nuclear Arms Control"

The nuclear triad approach to nuclear arms control deserves recognition for playing an important role in limiting and ultimately contributing to the reduction of their respective deployed nuclear forces, but it is unable to address the nuclear competition within the present geostrategic environment, where multiple states view nuclear forces as critically important to their long-term security. If nuclear arms control is to play a key role in preventing friction between nuclear powers and reducing nuclear risks in the 21st century, there needs to be a shift in focus and an expansion in participants.
