Research suggests that the nuclear weapons test facility at Punggye-ri was rendered useless by the last nuclear test, so North Korea has since been able to rely on an approach
On 12. June the meeting between Kim Jong-un and US President Trump is to take place. Trump expects to achieve his biggest political success yet by reaching an agreement with North Korea on the elimination of nuclear weapons. He sees this as a success of his policy, in addition to tightening sanctions and prere on China to "little rocket man" with "fire and fury" have threatened. What are the motives of Kim Jong-un or. the North Korean regime had to approach Sud Korea first and then offer negotiations to the U.S., having previously relied on demonstrations of strength through weapons testing, is speculation. One must ame that, given the U.S. withdrawal from the Iran nuclear agreement, there has been increased caution in the North Korean regime to engage in an agreement that has at its core the controlled dismantlement of nuclear weapons and nuclear weapons development.
The nuclear armament served North Korea not only as a deterrent against a possible attack, but also as a basis for negotiations from a position of strength. The fact that the offers were kept despite the development of the agreement with the does not necessarily testify to their seriousness. Like Trump, Kim Jong-un needs success and a stage to portray himself as a crude leader who is successful in his strategy.
