“Just War: Principles and Cases is clear, concise, and cogently argued. It belongs in the libraries of legislators and military men alike—anyone however remotely involved in deciding when a nation should go to war. Regan carefully considers all sides, every nuance of every question.”—U.S. Naval Institute Proceedings “The book is valuable in exploring the complexity in the context of modern war. The case studies force the reader to apply the theory to war as it is in reality, not war as we might want it to be in the ideal.”—Journal of Church and State “A readable, insightful, and provocative treatment of just-war thinking as it applies to historical and ongoing conflicts. . . . Regan’s book is an excellent choice for courses on the morality of war and the challenge of peace.”—Theological Studies “This book is well conceived, lucidly written, and shows an admirable blend of the moral, legal, and historical materials essential to assessing war thoroughly.”—International Philosophical Quarterly
