Counting animals in war: First steps towards an inclusive just-war theory

War is harmful to animals, but few have considered how such harm should affect assessments of the justice of military actions. In this article, we propose a way in which concern for animals can be included within the just-war framework, with a focus on necessity and proportionality. We argue that counting animals in war will not make just-war theory excessively demanding, but it will make just-war theory more humane. By showing how animals can be included in our proportionality and necessity assessments, we provide a crucial first step towards developing an animal-inclusive account of just-war theory.
