Just War Theorists have traditionally argued that combatants are moral equals, each permitted to kill their opponent regardless of the justice of their wars. Recently, this position has been challenged by ‘revisionist’ just war theorists, who hold that only combatants who fight in justified wars are permitted to kill. This view is often thought to be in deep tension with the law of war, and revisionist theorists are divided on the issue of what the legal implications of their view should be. However, in at least one area – the application of the law of war to United Nations Chapter VI peacekeeping operations – international law takes on a revisionist cast.
