This book highlights the increasing risk of North Korea’s collapse and considers the necessary actions that would enable the neighboring powers to prepare for such an event. North Korea's deteriorating economic conditions, its reliance on external assistance, and the degree of information penetration all provide hints of its collapse. Whether the chance is high or low, the collapse of North Korea and subsequent Korean unification would drastically alter the geostrategic landscape and profoundly affect the national interests of the regional powers—South Korea, China, the United States, Japan, and Russia. The most desirable scenario for a post-unification Korean Peninsula is a successfully developed and integrated non-nuclear Korea acting as a responsible regional and world stakeholder. This work considers the major challenges expected after a North Korean collapse, including the control of nuclear weapons, disorder in the immediate aftermath of collapse, and economic and social integration. The author then outlines how regional powers need to prepare to handle these challenges in order to minimize suffering and to set the foundation for long-term development and regional stability.
