Just war theory

Doctrine about when a war is ethically just

The just war theory (Latin: bellum iustum) is a doctrine, also referred to as a tradition, of military ethics that aims to ensure that a war is morally justifiable through a series of criteria, all of which must be met for a war to be considered just. It has been studied by military leaders, theologians, ethicists and policymakers. The criteria are split into two groups: jus ad bellum ("right to go to war") and jus in bello ("right conduct in war").
