The nature and function of the concept of proportionality as a limiting device in the jus ad bellum has always been subject to argument and some uncertainty. This uncertainty is exacerbated when the ad bellum rules are extended to non-state armed groups operating in the territory of another state. Contemporary efforts to reshape the jus ad bellum into a significantly more permissive framework to use force against non-state armed groups, places further pressure on the concept of proportionality. This leads to question of how to think about the conditions for the determinacy of the concept and whether in fact it functions less to restrain, and more to permit, the use of force.
