The Trump Doctrine

China controls the DPRK and when Trump defeats China on the economic issues, China will save face by giving up DPRK’s nukes in order to get a better trade/economic outcome.
The defeat of North Korea’s nukes doesn't come by confronting North Korean nukes; it comes from China giving them up because their economic survival is dependent on it.
China saves face in defeat by positioning the actual defeat at the feet of Kim Jong—un.
Everything else is chaff and countermeasures. - The Burning Platform

This makes more sense than anything else I have heard about North Korea. As to whether this scheme is actually came from Trump or his advisors, I don't care.
