The United States has attempted to secure North Korea`s denuclearization through a peace treaty for the peninsula, with North Korea conducting nuclear tests and developing ICBM technology capable of reaching the United States.  Before World War II, Korea was united for more than a thousand years and known as Goryeo and Joseon. After Japan colonized from 1910 to 1945, Korea was divided into two countries along the 38th parallel (now the Korean Demilitarized Zone). North Korea was administered by the Soviet Union in the years immediately following the war and South Korea was administered by the United States. North Korea invaded South Korea in 1950 and began the Korean War. The war ended in a stalemate in 1953. A peace agreement would replace the ceasefire that ended the struggle, if not the outbreak of small hostilities on the Korean Peninsula, but did not resolve the conflict between the two Koreas. On April 27, a summit between Moon and Kim was held in the South Korean zone of the Common Security Zone. It was the first time since the Korean War that a North Korean leader entered South Korean territory.
 Leaders met on the dividing line between Korea.  Kim and Moon signed the Panmunjom Declaration, in which they pledged to work within a year for a definitive peace in the Korean conflict and the total denuclearization of Korea.  The agreement also called for an end to military activities in the Korean border region and the reunification of Korea.  The Heads of State or Government also agreed to cooperate in the linking and modernisation of their railways.  US President Trump is speaking with his advisers to say he does not want a new summit with North Korean leader Kim before this year`s US presidential election. Needless to say, Trump could focus on his re-election campaign, his desire to engage in the nuclear issue has faded. Although Trump is selfless, chief foreign policy advisers are still trying to build a bridge of the nuclear deal between two leaders. Robert O`Brien, National Security Advisor, said: “President Trump has shown what is right for the American people until Election Day. The U.S. Special Representative for North Korea and Assistant Secretary of State Steve Biegun continued to conduct operational-level discussions with the DPRK. North Korea has slowed down its missile tests but remains focused on its nuclear program, diplomacy being at a standstill, North Korea has slowed down its missile tests.
 DpRK Foreign Ministry adviser Kim Kye Gwan mentioned that the personal relationship between two leaders is not enough to resume nuclear negotiations. . . .
