The denuclearization of the Korean Peninsula is an important goal for U.S. Asia-Pacific strategy. For a long time, the United States has used political, diplomatic, military, and economic compulsory means to intimidate North Korea. The U.S.' coercion is related to whether the United States has the determination to use force against North Korea; consider the credibility of North Korea's acceptance of the agreement and the consequences of Pyongyang's retaliation. Taking into account the current trend of relations between the United States and Democratic People's Republic of Korea (DPRK), the United States may not be able to achieve a unipolar model for denuclearization. In addition to strengthening its own military deterrence capability, the United States must also work with regional and major powers to solve the issue of denuclearization. If the United States does not change its current strategy, North Korea's nuclear threat will remain.
