Counterforce Dilemmas and the Risk of Nuclear War in East Asia

Abstract

The discovery of new Chinese nuclear missile silos, a seemingly escalating nuclear-conventional arms competition between the Democratic People’s Republic of Korea (DPRK) and the Republic of Korea (ROK), and the announcement that Australia, in concert with the United States and the United Kingdom, is pursuing nuclear-powered attack submarines are events that collectively indicate a worsening security environment in East Asia. Using geostrategic, operational, and technological factors as the basis for analysis, this paper contextualizes these and other developments and assesses the potential for nuclear war in East Asia in general and on the Korean Peninsula in particular. The most dangerous threat to strategic stability is a counterforce dilemma where the conventional weapons of the United States, China, and regional East Asian actors may create strategic instability by their intentional or inadvertent entanglement or use to target the nuclear forces of another state, resulting in pursuit of more secure second-strike capability by the countries of the region, and forming the heart of conventional warfighting and deterrence strategies. The many different conflictual or competitive relationships across the region make arms control initiatives unlikely to succeed, but the maritime nature of the geostrategic environment and the lack of existential threat that the United States and China pose to each other may offer fewer natural pathways to the use of nuclear weapons for either China or the United States than there were for the adversaries in the Cold War.
