united nations just 24 hours ago, you heard a diplomat say his country didn't yet trust the u.s. enough to move forward with disarming its nukes. but you then again, if you listen to president trump in west virginia just last night, you heard this -- >> you know the interesting thing, when i did it, and i was really being tough, and so was he, and we were going back and forth, and then we fell in love. okay? no, really. he wrote me beautiful letters. and they are great letters. we fell in love. but you know what, now, they will say donald trump said they fell in love! how horrible, how horrible is that. so unpresidential. and i always tell you, it is so easy to be presidential, but instead of having 10,000 people outside trying to get into this packed arena, we'd have about 200 people standing right there. >> gordon chang is author of "nuclear showdown north korea
