So here's the thing about Bush's memoirs: it's not a debate. He's not trying to justify, but simply explain, his decisions. It's a dry book. Much of it is boring play-by-play commentary, but occasionally it's a fascinating description of what really happened.
Bush is not introspective. He does not believe in second guessing decisions with the benefit of hindsight. It's not important what we know now; what's important is what he knew then. The purpose of his book was to explain what he knew then.
