Gray presents an inventive treatise on the nature of strategy, war, and peace, organized around forty maxims. This collection of mini-essays will forearm politicians, soldiers, and the attentive general public against many--probably most--fallacies that abound in contemporary debates about war, peace, and security. While one can never guarantee strategic success, which depends on policy, military prowess, and the quality of the dialogue between the two, a strategic education led by the judgments in these maxims increases the chances that one's errors will be small rather than catastrophic.
