A lengthy commentary on LG Bolger's book by Professor John Schindler:http://20committee.com/2015/01/06/am...e-by-strategy/

.... while I don’t agree with all the author’s arguments or conclusions, this is a work that all Americans who care about our national security should crack open and ponder.
Citing LG Bolger:
The war required a way to use a tactically superb force to contain and attrit terrorist adversaries. In this, America’s generals failed. We found ourselves impaled and bogged down in not one, but two Middle Eastern countries, and this on the best advice of educated, experienced senior military men and women who had all studied Vietnam in their service schools. Over time, piece by piece, the generals recommended slogging onward … Absent a realistic campaign concept in both countries, wars of attrition developed. Some saw it as a failure of imagination.
