Michael Walzer has argued that nations fighting a just war may be permitted indiscriminate attacks on enemy noncombatants if they are genuinely necessary to avoid an imminent and morally disastrous defeat. Critics often challenge this "supreme emergency" exemption from just war principles by arguing that it is inconsistent with his critiques of utilitarianism, realism, and sub-state terrorism. While morally troubling, I argue that Walzer's doctrine is both tightly cabined and consistent with his meta-ethical pluralism, his emphasis on the value of (...) political community, and his doubts about abstract philosophy's ability to answer pressing political questions.
