Starting and Stopping Wars

If a warring side may fight in pursuit of an aim up to some proportionality-respecting limit, then an important question is whether that side is morally required to stop fighting when it reaches that limit, despite not yet having attained its aim. The ‘Quota View’ answers this question affirmatively, while other views hold that the fighting may continue just as long as the projected future losses fall within certain limits. I criticize some of these other views, as well as a further argument that can be distilled from these sources, and advance a qualified version of the Quota View.
