We need to talk about Jus ad vim

This Review Essay looks at the two recent book-length publications on the emerging topic of Jus ad vim − justice of limited force: Brunstetter’s Just and Unjust Uses of Limited Force: A Moral Argument with Contemporary Illustrations (2021), and Braun’s Limited Force and the Fight for the Just War Tradition (2023). I argue that although both authors offer insightful and original contributions to the debate surrounding the ethics of limited force, their theorisation of jus ad vim provides the moral backing to military actions conducted by powerful Western states, rather than scrutinising them. Importantly, moreover, the project of jus ad vim, theorised in this manner, follows the Western conceptualisation of just war theory which has historically been used to further the interests of Western states at the expense of weaker nations.
