Gentile states that when the Tal Alfar lessons were applied to Baghdad, our troops were subjected to "supreme tactical vulnerability". That's pretty serious stuff to taxpayers like me and ol' Mom & Pop back home. How much of that statement is a reflection of reality on the street and how much of it is a reflection of the inherent friction that is becoming readily apparent between COIN proponents and for lack of better word, old school (geezers?), traditional military thinking? More importanty, how much is this in-house war detracting from success of the mission in Iraq?
