demonstrated the absence evof a plan and strategy and expertise to develop a good strategy here. so i'm concerned about. it i don't know whether the summit will happen. but if it does, the president needs to understand the history on the korean peninsula, what kind of actions the north koreans have taken in the past, where they promised to do something and then broken their word and go into this in a sober way to understand their intentions and to is a tempt to craft a diplomatic resolution of a very serious threat to our country. >> should there be some preconditions before this meeting takes place? >> well, i think for sure there ought to be preparation. what normally happens is the party will meet before the summit and map out the contours of an agreement, and apparently when the american delegation went to singapore, the north koreans didn't even show up. which is odd. but there ought to be a -- a plan and a lot of preparations so that when the president goes into the meeting, he understands the objectives and he has a reasonable chance of achieving those.
