New Keegan Book: Crack Pipe?

While in the Phoenix airport today ("Sky Harbor"), I noticed that John Keegan has a new book out on the Iraq war. The back cover blurb suggests that one of the questions addressed is how the U.S. forces (I believe the copy says U.S. and not Coalition forces, but I could be wrong) defeated an Iraqi army twice its size. Huh? First, the superiority in firepower and airpower should be obvious; not sure how much more detail would help me understand the conflict better (?). But second, isn't it the case that the Iraqi army largely--not entirely, but largely--just faded away?

But on a deeper level, isn't this book, well, a little early? I mean, aren't we still fighting the Iraq war? Seems like there are U.S. casualties every day, and just in the last week-10 days we had Operations Matador and Lightning. Isn't this like "The Great War," publication date 1916, or, maybe (?) more appropriately, a treatise on the Vietnam war published in 1967 (or 1971?). Not to prejudge the outcome of the current conflict--and, as John Kerry used to say, we can't fail in Iraq--but can we write the post-mortem while the body is still warm?

Which raises the question(s): Is Keegan cashing in? Selling out? Hitting the crack pipe? A little of all three?

OK, maybe it's the sherry and not the crack pipe.
