"No True Glory" by Bing West
Just starting to read this book. I was already going to buy it, but lucked out and got it for free for giving a brief to a bunch of Air Wing guys. A quick peruse suggests that it will confirm my suspicion that there were (and continue to be) some very stupid decisions by senior policy makers that make things harder than they have to be. Especially in the case of Fallujah.
Maybe I'll post a review when I finish.
