North Korea and the East Asian Security order: competing views on what South Korea ought to do

This article investigates South Korean views on how to deal with the two major security issues regarding North Korea: its nuclear threat and regime instability. In this Special Section, the article analyzes the ongoing debate in South Korea over the government's policy toward North Korea in regard to these two issues. It argues that uncertainties about these two major issues are shaping the regional order in East Asia. In particular, the different levels of cooperation between South Korea and the United States may affect the regional security order in East Asia. In analyzing policy options available to South Korea, the riskiest option would be to employ early preemptive attacks and accelerate the collapse of North Korea given the security dilemma-driven action?reaction in East Asia. Given that the role of China has become the most crucial factor in dealing with North Korea, the most promising strategy would be to reinforce guarantees of extended nuclear deterrence and prompt a soft-landing unification.
