This updated and revised second edition of Donald A. Wells's popular _War Crimes and Laws of War_, originally published in 1984, traces the rules of war since ancient times. The major sources of the rules or _laws_ of war are explored: the congresses of the Hague, Geneva, and the United Nations. But an abyss exists between what military manuals allow and what the congresses prohibit; this book attempts to resolve this dilemma. An important text for military college courses and international relations, as well as social philosophy courses. Co-published with the North American Society for Social Philosophy. Here is what reviewers had to say about the first edition:
