 What of redistributive wars? Too often arguments on this topic artfully distinguish between just cause and other conditions of jus ad bellum (Fabre 2012). Even when used by powerful states against weak adversaries, military force is rarely a moral triumph. It tends to cause more problems than it solves. Redistributive wars, as fought on behalf of the “global poor” against the “global rich”, would obviously fail to achieve their objectives, indeed they would radically exacerbate the suffering of those they aim to help. So they would be disproportionate, and cannot satisfy the necessity constraint. The theoretical point that, in principle, not only national defence and humanitarian intervention could give just causes for war is sound. But this example is in practice irrelevant (for a robust critique of redistributive wars, see Benbaji 2014).
