There have been a great many books published on the subjects of insurgency and counterinsurgency since the inception of the Global War on Terror (or “current, ongoing overseas contingency operations”, if you prefer); a number of these have focused on the U.S. Army’s mistakes in Vietnam or on the efforts on the United States and its allies in Iraq and Afghanistan. Jeremy Black’s recent contribution, Insurgency and Counterinsurgency: A Global History, offers more insight; it is a comprehensive history of insurgency and counterinsurgency warfare that is not limited in scope to the efforts of Western powers.
