Should we be more worried about North Korea?

With all of the attention paid to Iraq (and with the large amount of money and military resources being diverted there), are we not paying enough attention to North Korea? North Korea now admits that they have nukes, no great shock there, and make it sound like they won't give them up. The gov't is trying to get them to negotiate them away, not sure if that will happen or not. I, for one, am concerned that a country controlled by a brutal and not overly rational dictator now has nukes.
