 Traditionally, just war theorists divide their enquiry into reflection on the resort to war—jus ad bellum—and conduct in war—jus in bello. More recently, they have added an account of permissible action post-war, or jus post bellum. Others suggest an independent focus on war exit, which they have variously called jus ex bello and jus terminatio (Moellendorf 2008; Rodin 2008a). These Latin labels, though unfortunately obscurantist, serve as a useful shorthand. When we refer to ad bellum justice, we mean to evaluate the permissibility of the war as a whole. This is particularly salient when deciding to launch the war. But it is also crucial for the decision to continue fighting. Jus ex bello, then, fits within jus ad bellum. The jus in bello denotes the permissibility of particular actions that compose the war, short of the war as a whole.
