Their are two ways this will go:
1) Kim is in the best position he will ever be in. He will get massive concessions from Asia and the West to non-proliferate his technology, IF the USA can swallow our pride and engage in one on one dialogue which carries it's own pro's and con's. Since it took so much of his countries resources for nuke R&D he could likely shift resources and build an economy to engage Asia at this point and become a real power that is less threatening to it's neighbors. Kim may appear crazy but he is VERY shrewd.
2) The USA does not engage in one on one dialogue and we and other allies blockade North Korea to enforce non-proliferation. It is my strong opinion if this happens North Korea will use it's conventional forces to invade the South and will use it's nuclear deterrent to prevent us from using nukes to stop him from over-running the South.
Both these options are not very good but swallowing our pride and engaging in one on one talks may be the only way to avoid a massive military conflict.
They should send me as negotiator. I have a few things to say to Kim about the quality of life in NK, his priorities to his people and about what WILL HAPPEN to him and his booze collection in about 15 minutes if one of his nukes goes off over here.

Everything you stated above has been done before, in fact, it is largely responsible for how we got to the possition we are in today. One on one talks are the problem, not the solution.
