Noncombatants sometimes facilitate combatants waging war unjustly. Killing such noncombatants would sometimes help to eliminate the threat posed by the unjust combatants. But the justification of such eliminative killing turns on whether the person to be killed poses what I call a “mediated” or an “unmediated” threat. Mediated threats are agents who facilitate another agent in posing a threat, but only because the alternative they face is to sacrifice themselves as a means of saving potential victims from a threat. Unmediated threats may facilitate others in posing threats, but they do not face the alternative of having to sacrifice themselves to save others from a threat. Mediated threats often have a right to facilitate the unjust threatening actions of others, and when they do, they may not be targeted for eliminative killing. Unmediated threats more rarely have a right to facilitate the unjust threatening actions of others, and even if they act non-culpably, it is easier to justify targeting them for killing than it is to kill them as collateral damage. Most noncombatants who facilitate the actions of unjust combatants pose unmediated threats and are thus, but for the limits of necessity and proportionality, liable to being killed.
