 His discussion of ius in bello considers, among other things: the category of “innocents” and their immunities; the “doctrine of double effect” as applied to war; the self-defence rights of collateral victims; the attendant possibility of a war that is just on both sides (if the collateral victims decide to defend themselves); and the peculiarities of civil war and the permissibility of deceiving the enemy. It also dwells on topics that are not typically discussed by today's just war theorists. These include the difference between participating in highly risky missions and using suicide as a weapon, the justice of concerted confrontations (both mutually agreed and forced by one of the parties), the permissibility of military alliances with infidels, the rights of soldiers against the sovereign, and justice in the distribution of booty.
