I am finally getting around to reading Defense Policy Choices for the Bush Administration, 2001-2005 by Michael O’Hanlon (Brookings). My copy is the first edition which was published pre-9/11, but it is fascinating nonetheless, particularly his information regarding homeland defense, which appears quite prescient. He mentions Bin Ladin and Al-Qaeda for instance. I’ve only read a bit but I am impressed with the incisiveness of his mind. O’Hanlon also wrote an interesting piece for The Chronicle of Higher Education a few years ago that detailed the four defense technology philosophies that are current in policy circles. The book has since gone through a couple of editions, and he has a newer book titled Defense Strategy for the Post-Saddam Era, which I believe is a continuation of essentially the same material.
