It has been announced that North Korea successfully completed its light weighting, minimizing, variegating after its 1^st, 2^nd, and 3^rd nuclear experiment. Now Korea is in a situation under North Korea’s nuclear missile threat. We are pressuring North Korea’s denuclearization by bringing in the international community such as the United States, China, and United Nations. But such efforts are not enough. We need both diplomatic efforts and military response plans to North Korean threats. We must enhance our own strengths to get away from North Korea’s threats. The solutions provided by scholars up until now are limited to diplomatic characteristics and negotiations. However, it is hard to guarantee success in this approach and also requires a long time. With this respect, Hansun Foundation’s advanced national security research community sets the focal point of military response, debating on different plans Korea can select.
