I think it could be a GREAT idea (to steal an adverb from Mr. Trump).
1. Get the lil' fat boy to come here.
2. When he arrives, put him into handcuffs, or better yet, a straight jacket.
3. At that very same moment, Chinese troops cross the North Korean border and take over the government
4. The Chinese then seize the Nork nukes for dismantling, and install a new regime to replace Kim.
At that point, Trump releases the lil' fat boy to fly off to the retirement nation of his choosing... ;)
