going to be speaking to vladimir putin about. but also notable this is a president and we have seen this in his past foreign trip and briefings back at the white house who doesn't like the big, thick briefing books. he likes to receive a lot of the data he takes in in simple terms and tweet-like sentences as one describes it. he is a man who relies on instinct and impulse. he has in the past say that is what really made him successful as a dealmaker. what is notable, you have this dealmaker who is a veteran in making deals in the real estate world, not so much in the political and diplomatic landscape versus the spymaster as it were. a man vladimir putin is going face-to-face with his fourth american president. this is someone who has been at this for years. >> peter, thank you very much. so, you know, the whole question, cory, of the preparation for this. and going in with or without an agenda. how deep the preparation is.
