Why he’s right about Bush’s negligence on terrorism: “I went to graduate school with Clarke in the late 1970s, at MIT’s political science department, and called him as an occasional source in the mid-’80s when he was in the State Department and I was a newspaper reporter. There were good things and dubious things about Clarke, traits that inspired both admiration and leeriness. The former: He was very smart, a highly skilled (and utterly nonpartisan) analyst, and he knew how to get things done in a calcified bureaucracy. The latter: He was arrogant, made no effort to disguise his contempt for those who disagreed with him, and blatantly maneuvered around all obstacles to make sure his views got through.

The key thing, though, is this: Both sets of traits tell me he’s too shrewd to write or say anything in public that might be decisively refuted.” —Fred Kaplan, Slate
