Beckwith relates a history of America's wars that includes "What America Missed in U.S. History Class." She details why war sells, the fallacies of common justifications for war, true costs of war, and sensible alternatives. A Mighty Case Against War proposes that this culturally supported, deeply entrenched system of governmental violence is simply too costly, destructive, counterproductive, and inhumane to leave unchallenged. An easily readable book, this is a resource for youth and adult education, peacebuilding activists, and all who have wondered if a world beyond war is possible.
