This volume consists of previously published essays on war and ethics, written by Walzer after his Just and Unjust War1 and generally building on the version of just war theory (JWT) articulated in this classic work. In the Introduction, he points out that his view has changed in a few ways only: he is now, after the great number of “recent horrors,” more prepared to call for humanitarian intervention and more willing to support military occupations of failed states (xiii-xiii).
