While US war strategies have been dominated by the doctrine of counterinsurgency (COIN), Col. Gian Gentile and a group of dissident officers and defence analysts have questioned the efficacy of COIN - essentially armed nation-building. Drawing on Col. Gentile's experiences as a combat battalion commander in Iraq and his research into the application of counterinsurgency in a variety of historical contexts, Wrong Turn is a brilliant summation of Gentile's views of the failures of COIN, as well as a searing re-evaluation of the current state of affairs in Afghanistan.
