OKay, I agree wholly that the NOrth Korean situation is important. And if you are going to talk about rogue states then Kim Jong Il's regime would surely qualify (I am not fond of the term since it is both judgmental and totally subjective and seemingly based largely on "whoever ain't fer us is agin us").
BUt what right do nuclear powers have to say to those who want to be nuclear powers "No, we can have those weapons but you can't".
If the weapons are that dangerous and that offensive then outlaw them. Get rid of the ones you have first--then you have some credibility saying to North Korea, or Iran, or Iraq or your enemy du jour that they should not have them either.
Just something to consider amongst all the rhetoric.
