This article aims to find the answer to the question whether it is possible for the international society to denuclearize North Korea or not in the situation that North Korea is fast developing nuclear weapons and missiles in defiance of economic sanctions. For this aim, I approached this issue in the following steps. Firstly, I reviewed some basic points related to this issue. 1) I constructed the model for relationships between two countries. The types are confrontation, war and normal relationship. 2) I classified strategies for survival of a country. The types are self-reliance, forming alliance, collective security and world government. 3) I classified statuses of nuclearized countries. The statuses are being recognized, having declared and not having declared. Secondly, I checked the characteristics of the strategies of North Korea for its survival. Even though they are seeking the strategies of self-reliance, forming alliance and collective security, they are laying emphasis on self-reliance. This might be deeply related to their persistent seeking of nuclear weapons. Thirdly, I reviewed the development of North Korean nuclear issue focusing on the movements for nuclearization and denuclearization. Fourthly, I checked the opinions of some experts about the question whether its nuclearization is North Korea’s real goal or not. Fifthly, I constructed the dynamics of the North Korean nuclear issue focusing on the goals and means of the key players (North Korea, the U.S. and China). Sixthly, I checked the possibility of denuclearizing North Korea based on the analysis. Seventhly, I raised the task of preparing for the possibility that denuclearizing North Korea is hard to be attained.
