This article analyzes political processes of reform at the North Korean political system and suggests a potential way of future development conditioned by the features of current stage of the reform. Currently, the North Korean political system can be characterized by the system of the role division among the Party, Military, and Government. This system has been established by the measures taken by Kim, Jong Il's government. For example, it adopted the system of Cabinet Responsibility, distinguished the role of the Party from that of Government, and strengthened the role of Military through the Military-first politics. By the political reform, the Suryong Political System under Kim's rational power management is now experiencing serious challenges. As the leading role of the Workers' party weakened, it is now highly plausible that policy competition between political elites may develop in near future. In addition, the authority of the Workers' party is not as strong as before. As more and more people in North Korea doubts against the system justice, the Workers' party has hard time in persuading them. However, the emerging changes do not entirely imply that North Korea is carrying out a successful reform. Majority of North Koreans have strong beliefs on their system justice. In addition, the ongoing conflicts between North Korea and the USA still provide a strong reason for mass mobilization. Moreover, mass public separated from each other is hard to be organized under the rule of suppression. Therefore, for a future political reform, North Korea is required to make a new Suryong political system, called "a Triangular System," in which military system is transformed into the system with professional army and the Party, Government, and People's Congress acquire their independent and respective role.
