From Afghanistan to Angola, Indonesia to Iran, and Colombia to Congo, violent reactions erupt, states collapse, and militaries relentlessly pursue operations doomed to fail. And yet, no useful theory exists to explain this common tragedy. All over the world, people and states clash violently outside their established political systems, as unfulfilled demands of control and productivity bend the modern state to a breaking point. This book lays out how dysfunctional governments disrupt social orders, make territory insecure, and interfere with political-economic institutions. These give rise to a form of organized violence against the state known as irregular war. Research reveals why this frequent phenomenon is so poorly understood among conventional forces in those conflicts and the states who send their children to die in them.
