republican strategist alice stewart and samantha vinograd. thank you for being here. sam, the marker going into the meeting with kim jong-un was complete verifiable, irreversible denuclearization. that's not what the president got coming out. that's part rocess they're saying, this is not a one time deal. he got g, kind of, like joint statements that they have put out in past negotiations. do you see this as progress? >> i think it could be progress. i think we're going to have to wait for history to write whether this was a fool's errand or if it will result in long-tm stability. i'm worried about the systemic precedent set yesterday and we can call this a north korea model if you will. kim jong-un s rallying cry to proliferators and sociopaths around the world that if you push the envelope up to the brink of war, if you're that close, then what do you get? you get a summit, you get selfies, and you get concessions
