The Enduring Legacy of Just and Unjust Wars - 35 Years Later

Just and Unjust Wars - Papers and Audio Recordings

JUJW Conference Gallery Day 1

The first annual conference of NYU Law’s Tikvah Center for Law & Jewish Civilization focused on a single book: the seminal work Just and Unjust Wars: A Moral Argument with Historical Illustrations by Michael Walzer, a prolific philosopher and professor emeritus of social science at the Institute for Advanced Study in Princeton, New Jersey. Walzer is currently a joint fellow at both the Tikvah Center and the Straus Institute for the Advanced Study of Law & Justice.

Just and Unjust Wars, which originated in Walzer’s political activism related to the Vietnam War, is a foundational political ethics work that has had a significant impact on philosophical approaches to war. In the book, Walzer considers a range of moral issues related to military theory and armed conflict, using medieval just war theory as a basis for formulating a modern theory.

“The Enduring Legacy of Just and Unjust Wars—35 Years Later,” held November 8-10, was a multifaceted exploration of the issues raised by Walzer’s book and the changes in warfare that have occurred since. Topics included what has changed and not changed about war in recent decades, jus ad bellum (criteria to help conclude whether entering a particular war is justifiable) and jus in bello (guidelines determining the just conduct of war), nationality and humanitarianism, nuclear weapons, non-state terrorism and asymmetric warfare, and what constitutes victory.

The latter topic was the focus of the conference paper presented by Gabriella Blum, a 2010-11 Berkowitz Fellow at the Tikvah Center, an assistant professor at Harvard Law School, and a co-organizer of the conference. The other co-organizers were University Professor Joseph Weiler, director of the Tikvah Center, and Professor Iain Scobbie of the University of London’s School of Oriental and African Studies.

In an age of cyberwarfare and drones, Blum said, “The battlefield is everywhere, and we’re all potentially either targets or victims. The eternal question is whether that changes anything in the ethical prescriptions of the book, or if it just means that the ethical principles continue to endure and now it’s just a matter of translation and application in a new reality.”

While Walzer, too, was troubled by this question, the most crucial challenge posed at the conference, he said, was “the argument that if you stick to the rules of engagement prescribed by international humanitarian law or the Geneva Conventions or just war theory, if you fight like the good guys are supposed to fight, you won’t win…. That’s the most worrying argument that was made.”

Despite contemporary challenges to Walzer’s theory, Robert Howse, Lloyd C. Nelson Professor of International Law and a conference participant, has been deeply influenced by the book, which he read as a University of Toronto sophomore shortly after its publication.

“It had a major impact on me, especially Walzer’s evocation of a rich, complex moral vocabulary with which one could address the dilemmas of war,” Howse said. “The vocabulary deeply connected to the vocabulary of war but also allowed one to talk intelligently about the place of law in war.”

Walzer said he did not anticipate the longevity of Just and Unjust Wars: “I didn’t expect it to become a textbook at West Point. I certainly didn’t expect to be sitting at a conference 35 years later still talking about the book.”

The Tikvah Center conference was co-sponsored by NYU Law’s Institute for International Law and Justice andJean Monnet Center for International and Regional Economic Law & Justice, as well as the European Journal of International Law.
