This is not how it started. Kim the little Korean trump started on him. Plus he reinforced South Korea defense. Then he put pressure on China to strengthen their sanctions on North Korea. There is one thing China is afraid of and that is a nuclear Japan. Plus they don’t need a mutual trade war with the United States.

So for all these reasons Korea is talking denuclearization because those economic sanctions are limiting Kim’s own money. He does not care about his people everything comes down to money and for Kim besides money it’s staying in power.
