In this essay, CHEON Myeongguk explores the possible implications of the Ukraine conflict on the ROK attitudes regarding nuclear weapons. He concludes that the “ROK’s indigenous nuclear option would be a last resort as a deterrence measure against DPRK’s nuclear threat. This option would only be considered by the ROK if Donald Trump were reelected as President of the United States and decided to withdraw US forces from the Korean Peninsula and eventually withdraw the US nuclear umbrella protecting the ROK from DPRK aggression.”

CHEON Myeongguk is a visiting researcher at the Korea Institute for Defense Analyses (KIDA) working on DPRK weapons of mass destruction threats such as nuclear, chemical, and biological weapons and ballistic missiles. Deterrence, protection, counter measures, consequence management, and arms control are also included in his research scopes.
This essay is a contribution to the “Reducing the Risk of Nuclear Weapons Use in Northeast Asia” (NU-NEA) project, a collaboration between the Research Center for Nuclear Weapons Abolition, Nagasaki University, Nautilus Institute, and the Asia Pacific Leadership Network for Nuclear non-proliferation and Disarmament, is to reduce and minimize the risk that nuclear weapons will be used in the region by developing better understandings of the processes that could lead to the first use of nuclear weapons and the potential outcomes of such nuclear weapons use. In the first year of this three-year project, the NU-NEA project team identified over 25 plausible nuclear weapons “use cases” that could start in Northeast Asia, sometimes leading to broader conflict beyond the region. These nuclear use cases are described in the report Possible Nuclear Use Cases in Northeast Asia: Implications for Reducing Nuclear Risk. The project has commissioned five contributions to update the cases in light of the Ukraine conflict, of which this essay is the fifth.
