I think those two works are shaping a great deal of my response to Bin Laden's death. Bacevich's book is more polemic, then history. Still there's good stuff on the rise of the American military, and what it's citizens have come to expect from it. It argued a link between our foreign policy and our culture of consumption. 

Wright's book gives a history of Al Qaeda, explains America's indirect, and often unconscionable, contribution to the group's rise. But as he does this, he never falls off the rail and loses sight of the group's chilling goals, and their willingness to effect mass murder in pursuit of them. You can't finish that book, and not see how we've been damned by our own foreign policy. But at the same time, you can't finish the book and be sad that Osama Bin Laden is dead.

Both books are great, and necessary, reads.
