Not that I know what I'm talking about, but it seems to me that North Korea, even if its weapons program is more advanced than Iraq's was, poses less of a threat. Kim Jong Il strikes me as someone who has taken over a country and is running it for his own personal profit and finds that quite adequate. He doesn't seem to have ambitions to blow up everyone else. (Though of course he might find selling weapons accrues to his advantage.)
On a side note, doesn't it seem from both the professional and--ahem--personal lives of power-grabbing tyrants that they have an unusually high level of testosterone? Maybe if we got them some sort of treatment for that they would pose less of a threat.
