I think that Red China has told them that tis guy is for real, the exact opposite of Mr. Obama, and that they’d better hear him out, at the least. I could see Trump ordering a SLBM strike on all major targets if they keep threatening us, which I didn’t see the last three or four presidents doing.
I actually think the Chicoms are the turd in the punch bowl here. They probably do want the Norks to denuke but that is about it, no end to the war and no normal relations with the US. Rocket man may want more and the Chicoms will push back against him. They are using the Norks as a thorn in our sides as they have since 1953, but they just don’t want the nukes because in the long run the Japanese and South Koreans will develop their own nukes and the Chicoms and no one else in the area want the Japanese with nukes.
