Ius ad bellum, ius in bello

Ius ad bellum refers to the international law regulating the resort to force, while ius in bello is a synonym for international humanitarian law, and refers to the international law regulating behaviour in war. Today, the use of force between States is prohibited by a peremptory rule of international law: ius ad bellum has changed into ius contra bellum.
