This paper aims to propose a peace roadmap to reduce threats from nuclear and missile programs of North Korea and to realize a sustainable and stable peace state. As for the preparation and promotion of the peace roadmap on the Korean Peninsula, its ultimate goal should be to gradually minimize and manage the risk from North Korea’s nuclear and missile threats, thereby establishing a stable state of peace on the peninsula. To that end, this paper outlines the strategic roadmap that North Korea pursues with its missile and nuclear programs. In order to take a closer look at the strategic map of North Korea, this article collects pieces of Kim Jong-un’s remarks related to the North-U.S. relations, peace negotiation, denuclearization, and North Korea’s nuclear policy since Chairman Kim took office. Secondly, three types of peace roadmaps are proposed based on the highly possible advancement of nuclear and missile programs and a practically achievable state of peace. Thirdly, in order to realize the three types of roadmaps, this study presents: 1) multiple diplomatic strategies to deal with stakeholders, 2) an economic and life community for the two Koreas that can further promote peace in the aspect of inter-Korean exchange, and 3) the strategy for exchange and cooperation.
