"Just War Theory" raises some of the most pressing and important philosophical issues of our day. When is a war a just war, if ever? Do all soldiers in war have moral equivalence? What is the difference between combatants and non-combatants? This book brings together some of the most important essays in this area written by leading scholars and offering significant contributions to how we understand just war theory. The essays have all appeared in the "Journal of Moral Philosophy," an internationally recognized leading philosophy journal.
