According to International Humanitarian Law and many writing on just war theory, combatants who foresee that their actions will harm or kill innocent non-combatants are required to take some steps to reduce these merely foreseen harms. However, because often reducing merely foreseen harms place burdens on combatants – including risk to their lives – this requirement has been criticised for requiring too much of combatants. One reason why this might be the case is that combatants have duties to each other and to their compatriots, such as duties to keep them safe, which are weighty enough to override their duties to foreign non-combatants. In this article, I argue that arguments against the requirement to limit merely foreseen harms which rely on combatants' associative duties fail to establish that it is permissible for combatants to prioritise their own safety over the reduction of merely foreseen harms. Although the argument based on associative duties might work in individual cases, factors peculiar to the situation of combatants mean that such justifications are not normally available to them.

War is harmful to animals, but few have considered how such harm should affect assessments of the justice of military actions. In this article, we propose a way in which concern for animals can be included within the just-war framework, with a focus on necessity and proportionality. We argue that counting animals in war will not make just-war theory excessively demanding, but it will make just-war theory more humane. By showing how animals can be included in our proportionality and necessity assessments, we provide a crucial first step towards developing an animal-inclusive account of just-war theory.

Combatants who attempt to obey the laws of war often have to take considerable risks in order to effectively discriminate between legitimate and illegitimate targets. Sometimes this task is made even more complicated by systemic factors which influence their ability to discriminate effectively without unduly risking their lives or the mission. If they fail to do so, civilians often pay the price. In this paper, I argue that to the extent that non-combatants benefit from the attempt to fight justly, and to the extent that wars in which combatants attempt to fight justly can be understood as a system of social cooperation which produces both burdens and benefits, non-combatants have a responsibility to shoulder their fair share of these burdens. Thus, if combatants (and by extension enemy non-combatants) are disproportionately burdened in a conflict, non-combatants ought to take on some costs, for instance in order to reduce the strain imposed on combatants by systemic factors such as the availability and distribution of resources.

This book argues that the risk of harm in armed conflict should be divided equally between combatants and enemy non-combatants. International law requires that combatants in war take 'all feasible precautions' to minimise damage to civilian objects, injury to civilians, and incidental loss of civilian life. However, there is no clear explanation of what 'feasible precautions' means in this context, or what would count as sufficiently minimised incidental harm. As a result, it is difficult to judge whether a particular war or offensive actually satisfies this requirement. Just war theorists often consider it common sense that merely not intending to harm innocent civilians is not sufficient, but there is little clarity in the literature regarding what this means. One crucial question that is almost always overlooked is that of what the appropriate baseline distribution of risk should be. This book defends the Minimal Harm Requirement, which states that combatants should make an effort to reduce merely foreseen harm to enemy non-combatants to the lowest reasonable level. In order to assess which risk impositions are reasonable, and which are not, an egalitarian baseline should be adopted, suggesting that other things being equal risk of harm should be distributed equally between just combatants and unjust non-combatants. This book will be of much interest to students of just war theory, ethics, security studies, and international relations.
