Put yourself in the place if Kim Jong Un. Trump wants you to give up your nukes in exchange for a "great deal"? How is that working out for Iran? Promises made, nukes dialed back, inspections support them and now Trump wants to welsh on the deal. Hmmm. Perhaps that's not a good deal after all. Remember Gaddafi? He gave up his nukes and whammo - he's gone. Perhaps I'll keep my nukes. Seems safer that way. Besides - I kinda like "Rocket Man".
