My other thought is that the guy really just is insane. To reductionistic? Probably. But even if you made an argument for strong rationality, you simply couldn't make any argument for empathy.
This is all of course just my opinions. I study educational psychology these days, not political science or sociopaths. One common theory, it seems, is that Kim Jong-il is trying to get the attention of one President Obama (and, again, up the DPRK's bargaining power). Should be interesting to see how this administration deals with North Korea, and whether it makes a difference. I don't think the last administration did a poor job with North Korea, either - at this point I just wonder what tact anybody could take that would actually produce favorable long-term results. Again, this is a question I am in no way knowledgeable enough to answer.
