The fact is, the NKs don't want a light water reactor, or economic aid, or security guarentees, what they want is what they already have-the bomb. Negotiations are pointless, they will never agree to give them up, because they realize that nukes make them immune from attack. And we will never convince them they are wrong, for the simple reason that they aren't. How should Iran read this? Iraq gives up it's weapons, and gets invaded, NK gets the bomb, and doesn't. The lesson is crystal clear, get the bomb and get it quick.
