War is certainly an especially complex and dangerous endeavour, but these facts do not generate special moral principles, any more than natural disasters or outbreaks of disease generate special moral principles. Individualists hold that moral evaluations and prescriptions are properly directed towards individuals, addressing their rights and duties. A more permissive stance towards the range of legitimate targets for just combatants will be taken to apply to unjust combatants as well. In contrast, contributions that specifically enable combatants to fight, rather than live, can ground liability, and render a civilian a legitimate target. Civilians make many indirect contributions to the unjust threats posed by the members of their armed forces. They provide, amongst other things, weapons, vehicles, specialist clothing, food, medical supplies and money. Jeff McMahan and Cecile Fabre argue that even if civilians contribute to unjust wars, their contributions are typically too small or insignificant to render lethal force a proportionate response.
