Article Compliance with International Humanitarian Law: Democratic Third Parties and Civilian Targeting in Interstate War

This article examines compliance with international laws prohibiting the inten-tional targeting of noncombatants in interstate war, specifically focusing on the role of third-party states in enforcement. We argue that the expectation of third-party coercion, when sufficiently high, can induce war participants to comply with this body of law. We identify the conditions under which combatant states will anticipate a high likelihood of coercion, demonstrating that third-party states are most likely to coerce combatants when they have both the willingness and oppor-tunity to do so. Democratic third parties that value the rule of law and human rights possess the willingness to coerce war participants, while strong allies, trade partners, and intergovernmental organization (IGO) partners with existing ties to the combatant state have the opportunity to engage in coercion by linking combat-ant behavior to the provision of benefits or imposition of costs. Based on this logic, we hypothesize that war combatants who have ratified the Geneva/Hague Con-ventions prohibiting the intentional targeting of noncombatants during war are more likely to comply with the legal obligations included in those convention
