host: let me put that point to nicholas kralev. somebody, if president trump is not the leader in terms of diplomatic efforts -- can rex tillerson do it, or vice president pence -- perhaps not dennis rodman -- can it be somebody else? if yous: at one point, recall, the president didn't with kim jongng un. the administration has been all over the place and i don't criticize lightly. in governmenteen so i don't -- not having it and the difficulty of it, i know a lot a difficulties of my work as journalist and author but i've not been in those shoes. inthe same time, again, terms of policy, you cannot carry out diplomacy if there's policy to implement and we just don't know what his mood be tomorrow or next week or next month about meeting. meeting with some north koreans is an option, i would diplomatnd an american with that south american delegation going to p'yongyang a lower levelit's diplomat, just to have eyes and ears there, rather than hear second-hand accounts from people who have been in those meetings, and start from there.
