North Korea is not an insane nation. It is not a crazy nation.
I think, as a general matter, clearly, the United States globally supports the development of democracy and the democratic yearnings of all people.
I would not suggest the U.S. should sit down with the North Koreans bilaterally immediately after they've fired missiles - because the appearance is that you reward bad behavior. But if North Korea behaves for some period of time, I would pretty much favor direct talks.
