korea, that ended in failure. and north koreans have been very, very good at doing three things. stringing out negotiations, wringing out economic concessions and then ultimately walking away from any hard commitments they make. we have to be very, very cautious heading into this. that we re not heading for a repeat of exactly that kind of process and dynamic. by the way, that s exactly what president obama tried to get out of it to break that pattern. all of that said, the bottom line here is that both of these leaders want this meeting. kim jong-un wants it and needs it because it gives to him what his predecessors, grandfather and grandfather could never get. president trump needs it because he s so hyped his ability to pr do, that it would be a failure up front. at best this is the start of a process, not the end of one and will take a long time to do this right, meticulous preparation, negotiation, and we got a long road ahead of us.
