North Korea says "no way" will disarm unilaterally without trust

I feel the denuclearization of North Korea will still take a long time, because it is almost impossible for the US or North Korea to trust each other, no matter what Trump or Kim say in their conferences. Neither the US or North Korea are willing to give up their nuclear weapons and show vulnerability towards each other. The circumstances in our world today make it extremely difficult for nations to give up their power, and I feel that it will still take a very long time for denuclearization of countries. -Sho Kawajiri-
