After some years of living in East Asia, I reconciled mutual contradictions a long time ago and determined them to be parts of the whole truth, even if contradictory (the whole 'yin' & 'yang' kind of thing). An Asian business colleague can preface his "I think I'll just pass on the cocktails in the lobby bar and go get some sleep if you don't mind", even after he has just told you that he is very well rested and full of energy after the long flight and happy to have landed in America).
That is why I tend to agree that in an Asian context, as with another Freeper here, that we can sign a meaningless bilateral piece of paper with the Chia-ites, and yet behind the scenes, continue to do everything to subvert Kim Jong il, create/nurture/fortify a domestic fifth column there. (My only concern would be the larger, Western ramifications of such double dealings). We could seek to remove Kim Jong il by social upheaval, and/or by coup d'etat betrayal by the inner circles, by interests that could be controlled by the West and eventually co-opted into a larger plan of peaceful, staged reunification with the South. This, IMHO, would be much more advisable than a full scale, head-on military onslaught by US forces against Pyongyang (the Korean People's Army and particularly their thousands of suicide commandos will not throw down their weapons and run like the Republican Guards)--although of course we should never take THAT option off the US-DPRK table, either.
