This fantastic Journal editorial states the importance of handling Saddam by paralleling the situation with the current North Korea drama. (subcription required)

It is being argued, principally by U.S. senators who don't want to face up to the risks attendant to regime change in Iraq, that North Korea is the greater danger and demands the more immediate attention. Theirs is mainly a diversionary tactic. The administration is working the Kim Jong Il problem in a systematic way, as is evidenced by its proposal for a multilateral approach. Kim, unless he is totally mad, is not a clear and present danger. Terrorists equipped by Iraq with deadly poisons are however an immediate and insidious threat. The only answer is to rip out the roots that give them their sustenance.
