If you want to make sense of the latest confusing news out of North Korea--in this case, Pyongyang's claim to have mastered the difficult process of uranium enrichment, giving them a complement to their plutonium program as a means to developing nuclear weapons--then you should read the story I wrote recently about this prospect and how it could complicate the Obama team's dealings with the Hermit Kingdom. Whether or not the Norks have a uranium problem has been a long-running--and politically-charged--debate within the intelligence community. And while we can never take Kim Jong Il at face value, the evidence does seem to be building in a disturbing way.
