It makes no sense for NK to keep on holding nukes imo. This is a Kim stunt not a Trump stunt, Kim just trying to get best terms he can but can't appear weak to his people. I think Kim will come round because i don't think he has any other sensible choice, while Trump is there all the nukes are doing is keeping his country poor when it could become rich, so i'm thinking Kim will re-think because he's on a timer and has no choice anyway imo.
I think this is the first time in 50yrs that America is trying to find a solution without removing the NK dictatorship, its the first time America is trying to work WITH NK rather than trying to take it over like people like watso expect as the norm from the USA and shows that with Trump America is changing.
The best thing Kim can do is get a move on while Trump is offering the window or he'll remain in a time vortex like he has for 50yrs, If the Dems win next election they won't negotiate with him, it'll go back to how it was..... divide and conquer.
