March 8, 2018: South Korean National Security Adviser Chung Eui-yong briefs senior White House officials and President Trump on high-level talks between North and South Korean leaders in Pyongyang a few days earlier, including Kim Jong Un`s promises not to conduct nuclear or missile tests during talks with the United States. Chung Eui-yong announces, after his meeting with Trump on the White House lawn, that Trump has accepted Kim Jong-un`s invitation to “meet with Kim Jong Un by May to achieve lasting denuclearization.” The meeting would be the first between a current U.S. president and a North Korean leader. U.S. officials said in the evening that discussions would be held at a location and date yet to be determined and that “in the meantime, all sanctions and maximum pressure must be maintained.” In October 2018, South Korean Foreign Minister Kang Kyung-wha said he wanted U.S. Secretary of State Mike Pompeo to accept a declaration to end the Korean War as part of security guarantees to strengthen North Korea`s confidence in a denuclearization agreement. Although Pompeo said he was happy to negotiate with Kim Jong-un on the dismantling of nuclear facilities at the Yongbyon Nuclear Scientific Research Center, he was hesitant to comment on the possibility of a “declaration of war of the end of Korea.”   After the end of the Hanoi Summit in February 2019 without agreement between the United States and North Korea, the then North American Deputy Minister, Choe Son Hui , now the first deputy foreign minister, attempted to present Kim as a negotiating point. She said Kim had ignored petitions from the munitions industry asking her not to denuclearize.30 The true extent of internal disagreements – and the ability of North Koreans to express dissenting opinions – is impossible to measure and it is not known to what extent the increase in internal resistance to denuclearization was a tactic to encourage the United States to less require North Korea instead of being a means of explaining the real political constraints. It seems certain that North Korea sees Hanoi as a failure, and Kim wants to reaffirm its harshness – an idea reinforced by subsequent missile tests and the alleged punishment of North Korean negotiators.31 It is fair to believe that, with as much power as Kim in his regime, he is not all-powerful and must balance competing interests.
