David Kilcullen is one of the world's most influential experts on counterinsurgency and modern warfare, a ground-breaking theorist whose ideas "e;are revolutionizing military thinking throughout the west"e; (Washington Post). Indeed, his vision of modern warfare powerfully influenced the United States' decision to rethink its military strategy in Iraq and implement "e;the Surge,"e; now recognized as a dramatic success. In Counterinsurgency, Kilcullen brings together his most salient writings on this vitally important topic. Here is a picture of modern warfare by someone who has had his boots on the ground in some of today's worst trouble spots-including Iraq and Afghanistan-and who has been studying counterinsurgency since 1985. Filled with down-to-earth, common-sense insights, this book is the definitive account of counterinsurgency, indispensable for all those interested in making sense of our world in an age of terror.
