have president trump meeting with his south korean counterpart, moon jae-in. and you know, after the hugs that we saw between president moon and kim jong-un last week, what does president trump need to find out from or get on the same page with south korea on at this point? >> at this point, president moon, for his own reason, is very eager to move forward. he would be bringing back, you mentioned the hugs. they met for three days, and he'll be bringing back the message that he's serious about denuclearization, but president trump, you have to give something in return. you have to give it now. and i think if you give it now, maybe there is still a path ahead. so president moon is playing a very, very important role in brokering between moon and trump. sorry, trump and kim. >> okay. joseph yun, always good to have your expertise. thank you.
