Ever get the sense that the whole world has changed? Well, it has. And it's all because North Korea Leader Kim Jong Un -- a rogue dictator with nuclear weapons and the power to start World War III -- has reportedly said that he wants to meet with President Trump and that he will stop testing his nuclear weapons, and possibly even move toward denuclearization. A de-nuk'ed North Korea? Who would have imagined such a thing just six or seven months ago when Kim and Trump were trash-talking each other something fierce. Lots of questions. Like this one: How much credit does Trump get for these developments? Answer: A lot.
