Few concepts in modern warfare are invoked as frequently, and misunderstood as deeply, as proportionality. In public debate, the term is often reduced to a simplistic equation: if one side suffers fewer casualties, it must have acted disproportionately. This framing is emotionally powerful, but legally and morally inaccurate.
In Beyond Power: Israel and the Struggle for the Ethical State, Daniel Bookman challenges this reductionist view and reexamines proportionality within its proper ethical and legal context
The result is a far more complex and demanding moral standard than commonly presented in headlines or social media discourse.
Under international humanitarian law, proportionality does not mean equal casualties. It does not require symmetrical destruction. Instead, it asks whether the anticipated military advantage of a particular action outweighs the expected incidental harm to civilians. The focus is intent, necessity, and reasonable military judgment at the time of decision, not retrospective casualty comparisons.
This distinction is critical.
If proportionality were measured purely by numerical symmetry, defensive superiority would become immoral by definition. A nation that invested in missile defense systems or intelligence capabilities would be punished ethically for reducing its own casualties. That interpretation would invert the logic of self-defense and reward vulnerability rather than responsibility.
Proportionality also operates within the broader framework of just war theory. Ethical warfare requires discrimination between combatants and noncombatants, necessity in achieving legitimate military objectives, and avoidance of unnecessary suffering. The principle does not demand zero civilian harm. It demands that civilian harm not be excessive relative to concrete and direct military advantage.
The moral difficulty intensifies in asymmetrical conflicts. When non-state actors embed military infrastructure within civilian populations, use human shields, or deliberately blur the distinction between combatants and civilians, proportionality assessments become more complex. The ethical burden does not disappear, but neither does the responsibility of those who create those conditions.
Bookman’s analysis situates proportionality within a larger argument about the ethical state
An ethical state does not seek power for its own sake. It seeks to preserve moral order, protect its citizens, and maintain principles even under existential threat. The obligation to defend oneself is not contrary to ethical governance. It is part of it. However, defense must still operate within moral constraints.
This is where public misunderstanding becomes particularly damaging. When proportionality is equated with body counts, moral reasoning is replaced by emotional reaction. Images of destruction provoke outrage, and outrage demands immediate judgment. Yet the ethical evaluation of warfare requires sober analysis of intent, operational context, and the strategic objectives involved.
Consider the concept of deterrence. A response designed to prevent future attacks may appear forceful in the short term but serve a stabilizing function in the long term. If an action degrades the military capacity of an aggressor and reduces the likelihood of continued hostilities, its proportionality cannot be assessed solely by immediate visible impact. Long term consequences matter.
This does not grant carte blanche to states. Proportionality is a real constraint. It requires commanders to weigh intelligence, anticipate collateral damage, issue warnings where feasible, and adjust operations to minimize harm. It demands constant ethical calibration under pressure. The moral standard is rigorous, not permissive.
The broader philosophical question raised in Beyond Power is whether modern discourse has lost the capacity for such nuanced moral reasoning
When power is viewed as inherently suspect and self-defense as inherently aggressive, proportionality becomes a rhetorical weapon rather than a legal and ethical principle. The result is not greater justice, but confusion.
Ultimately, proportionality in war is not about equal suffering. It is about moral restraint in the pursuit of legitimate defense. It recognizes that war is tragic and destructive, yet insists that even in conflict, ethical boundaries must hold.
Understanding proportionality correctly does not end disagreement. But it elevates the conversation from emotional reaction to principled analysis. And in an age of rapid information and polarized debate, that shift is essential for any serious discussion about ethics, sovereignty, and the responsibilities of the modern state
