Just War Theory and the Normalization of Civilian Harm in Contemporary Conflict

Contemporary warfare increasingly centers on civilian populations rather than discrete battlefields, placing unprecedented strain on ethical frameworks designed to regulate armed conflict. Just War Theory, long regarded as a foundational moral guide for the use of force, purports to restrain violence through principles such as just cause, proportionality, and civilian immunity. Yet in conflicts marked by prolonged occupation, asymmetrical power, and densely populated environments, these principles appear unable to prevent predictable and sustained civilian harm. This paper argues that in modern warfare, Just War Theory has shifted from a framework of moral restraint to a language of moral legitimation. Through analysis of contemporary conflict, with particular attention to Gaza as a moral stress-test, the paper demonstrates how ethical and legal vocabularies are increasingly deployed post hoc to rationalize outcomes rather than to prevent them. It further examines how abstraction, procedural legality, and responsibility diffusion insulate state actors from accountability while rendering civilian suffering administratively tolerable. The paper concludes that when civilian harm becomes foreseeable and structurally embedded, ethical frameworks grounded in proportionality and discrimination lose their restraining function. In such contexts, moral evaluation must move beyond compliance toward consequence-centered accountability if it is to retain normative force.
