"Jim Mattis I first met when I went to the Pentagon. He was a young colonel. And as Senator Nunn has pointed out, he had a reputation even then. This is somebody to watch. He is young. He is smart. He does not really belong behind a desk, although he may belong there right now, but at that time, he wanted to get out into the field. He is a warrior by nature... But that is really not why we are here. If he were only a great warrior, you would say, well, there are a lot of other warriors as well. He comes because he is a man of thought, as well as action. And sometimes it is said you can judge people by the friends he makes, the company he keeps, but also by the books he reads. General Mattis has some 6,000 books in his library, most of which, if not all of them, he has read, and he can refer to either Alexander the Great, General Grant, Sun Tzu. And I suspect he is probably the only one here at this table who can hear the words “Thucydides Trap” and not have to go to Wikipedia to find out what it means. And so he is a scholar as well and a strategic thinker as well as a great warrior."
