The Democratic People's Republic of Korea (DPRK or North Korea) remains one of the most critical security challenges for the United States and the broader international community. In particular, North Korea's willingness to undertake provocative and destabilizing behavior, including attacks on the Republic of Korea (ROK), its continued development of nuclear weapons and long-range ballistic missiles, and its proliferation of weapons in contravention of United Nations Security Council resolutions (UNSCRs) pose a serious threat to the United States, the region, and the world. Since assuming control in December 2011, Kim Jong Un has solidified his grip on power by embracing the coercive tools used by his father and grandfather. His regime has used force and the threat of force combined with inducements to quell domestic dissent and strengthen internal security; co-opt the North Korean military and elites; develop strategic military capabilities to deter external attack; and challenge the ROK and the U.S.-ROK Alliance. In April 2013, Kim announced the "byungjin" policy, which emphasizes the parallel development of the country's economy and nuclear weapons program, to reinforce his regime's domestic, diplomatic, economic, and security interests.
