Inspired by his experiences as a French military officer and attache in China, Greece, Southeast Asia, and Algeria, the author realized the "need for a compass" in the suppression of insurgency, and he set out to "define the laws of counterinsurgency warfare, to deduce from them its principles, and to outline the corresponding strategy and tactics." His book provides an analysis of how to countermine insurgency and the elements that might hinder its defeat. Written in 1964, the book in its new printing is as relevant now as it was 40 years ago-providing a template for the defeat of today"s insurgents and terrorists.
