and i think they are leaning forward now without any overt planning, getting ready to back up diplomacy with hard military power. >> talk to me finally about a point you made a few weeks back about kim jong-un's sister going to the olympics and the coverage and interest she generated in south korea. we have no understanding for that here. >> no, i think kim jong-un's sister i think first of all she's the most trusted family member and advisor to kim jong-un. she put a human face to this totalitarian regime. so i think in terms of kim jung-un trying to have this huge makeover, she was very useful in that regard. she represented the north korean delegation going to the south korean olympics. and she was hugely popular and well received in south korea. again, she put a human face in to north korea. >> our great thanks on a friday night. we really appreciate any time we can have you both on. thank you so so much. coming up nearly a week
