Informative, well-researched, but I can't get around the military mindedness--if you will--and the book's overall tone. I would say it's boarderline bias, but I don't think this is the author's intent.
One day, some of us may find ourselves, inadvertently, in the position that today's "insurgents" have. Best to know your enemy; the nature of the beast, before the inevitable. And for "true-believer" U.S. patriots, maybe they can get their thinking straightened out and even see the error of their ways. We can only hope.....as we prepare and tune our minds to a constantly shifting paradigm.
If you'd stay posted on the latest in "The Great Game"(the hegemonic/imperialist competition for control of Central Asia; first coined by Sir Ruyard Kipling), this is invaluable.
If you like this book then I would suggest you to read "confession of an economic hit man" by John Perkins
try Charlie Wilson's War. Its Ghost Wars Lite.
