processed, it has got to be progress. i think to get away from what we have done in the past, at least we have to have sizable deliverable. if we are too serious, kim jong-un seriousness, then we have to test it. so far i see no signs that we're seriously testing the hypothesis that he wants to denuclearize. and if we get into this action for action, little by little, it can drag on forever and in the end, we have no progress. i would like to see coming out tomorrow, from the declaration, that jean mentioned, some immediate steps that they will do, we do some security assurance, they do denuclearization. so it is fair. you got to do a little bit of each. but let's see something that shows kim jong-un is indeed serious. >> yeah. and ambassador yun, thank you
