of when, and president trump did that in his tweet saying we'll meet with you whenever you say so. in my move, that's a bad move. north korea should not be the one deciding when the meetings take place or what's discussed. this has to be coordinated between the two sides as well as other players involved. >> general yun brings up a good point. 18 days is not a long time. is there really going to be enough time between now and june 12th to iron out all of these issues that both countries have that they could actually pull this summit off on june 12th? is that physically possible in any way, shape, or form? >> well, i mean, i think we need to lower our expectations, ryan, as to what this meeting is going to achieve. i don't see any problem, and i don't think ambassador yun would either have a problem with president trump meeting with kim jong-un. this is not going to be a nuclear negotiation.
