Just war theory is the moral foundation of the modern law of armed conflict. It begins with the recognition that civilian deaths in war are tragic and morally weighty. But it also insists that tragedy alone does not determine legality or morality. Jus in bello is built on discrimination and proportionality, not on the fantasy of bloodless war or a morality in which both sides must be harmed equally. The purpose of restraint is not to make war painless. It is to limit suffering while preserving the possibility of lawful self-defense against enemies who will not be restrained.

The most damaging move in today’s discourse is the treatment of numbers as verdicts. Civilian-to-combatant ratios are presented as legal conclusions. Counts of destroyed buildings are treated as evidence of intent. Claims about food supplies, aid convoys, and infrastructure damage are wielded as if they automatically determine whether a military is complying with international law. Context is dismissed as excuse-making. Command intent is treated as propaganda. Enemy conduct is minimized or ignored. This is not analysis. It is the conversion of war into a spreadsheet and then the conversion of that spreadsheet into a moral tribunal.

Our current global infatuation with civilian-to-combatant ratios or aggregated death totals is not and cannot be how war works. Raw numbers are not law. They are not proof of distinction or proportionality. They are not evidence of intent. They are, at best, one contested data point among many. In urban warfare, they are almost always unknowable in real time.

Yet in Gaza, the world has watched casualty figures released within minutes of operations, updated daily with a precision down to single digits, often presented as an emotional plea rather than an analytical assessment, as if the most important legal and moral questions could be resolved by an accountant’s ledger. This is unprecedented in modern conflict, especially in dense urban combat, and it is operationally implausible on its face.

In Gaza, numbers are announced almost immediately despite rubble, tunnel collapses, secondary explosions, and active firefights. Determining who was present in a structure, who was directly participating in hostilities, who was coerced into remaining, and who was killed by regrettable but unavoidable secondary effects requires investigation, intelligence fusion, and time. Treating instantaneous casualty reporting as legal truth is not accountability. It is epistemic fiction.

At the same time, there is a powerful and understandable human impulse to compare Gaza to something else. To another battle. Another city fight in Iraq or Syria. Another war that might help make sense of the suffering. Inevitably, such comparisons drift toward hyperbole—the point of which is to overthrow the process of reasoned distinction-making through which law-bound nations act while declaring the enemy’s most heinous actions to be permissible in the face of an absolute world-historical evil that is often named but never demonstrated.

The sad truth is that there is no meaningful comparison to Gaza. Israel is not fighting a counterinsurgency shaped over two decades with control of terrain and population. It is not a conflict in which civilians had viable options to flee to neighboring states. It does not involve the obliteration of a city by a wonder weapon. It’s a war fought in a sealed enclave where one side spent more than 20 years preparing the battlefield, constructing hundreds of miles of tunnels beneath homes, hospitals, schools, and streets, and where civilians have not been permitted safe passage through borders such as Egypt. It is also a war being fought in the age of instantaneous global communication, when algorithms on platforms like TikTok, X, and others push the most horrific images of war to billions of people in real time.

Some of the images we see from Gaza are tragically real. Others are fabricated, misleading, or stripped of context that would give them meaning. All are consumed faster than facts can be verified. In this environment, people understandably struggle to know what is true or false, legal or illegal, moral or immoral, as war unfolds in real time. This confusion does not restrain violence. It incentivizes lawfare and accelerates the collapse of legitimacy in ways that the world’s armies have never experienced before.

In Gaza, one side follows the law of war as a matter of doctrine and accountability. Hamas, as a matter of strategy, deliberately seeks to erase the distinctions the law depends on. Hamas fighters do not wear uniforms. They operate from within civilian structures. They embed command centers in hospitals, weapons in schools, and fighters in residential buildings. They deliberately exploit civilian density and protected sites to complicate targeting and magnify poststrike narratives. Under those conditions, it is impossible for any outside observer to distinguish in real time who was participating in the hostilities and who was not. It is especially impossible for a Hamas-controlled authority to credibly separate combatants from civilians, given that its incentives lie in every case in the opposite direction.

This is not an argument for indifference to civilian suffering. The opposite is true. Civilian deaths should never be minimized or excused. They should be investigated, understood, and punished when unlawful. A professional military should always seek to reduce civilian harm, not because it is politically convenient, but because it is morally right and strategically wise.

But moral seriousness is often something entirely different than the moral theater that plays well on social media. Moral seriousness does not declare guilt by statistics. It does not erase the difference between deliberate murder and collateral harm. It does not treat the kidnapping and murder of civilians as morally interchangeable with deaths caused in the course of lawful military operations against an enemy that embeds among civilians. That equivalency is not compassion. It is a surrender of judgment.

The United States has lived this reality in its own urban fights long before Gaza. In Fallujah, Ramadi, Tal Afar, and Mosul, and Syria’s Raqqa, American forces confronted enemies who deliberately embedded among civilians, transformed mosques, schools, hospitals, and apartment blocks into defensive strongpoints, and waged information warfare alongside kinetic combat. The United States adapted tactics, improved intelligence, tightened targeting processes, and increased precision. It did what professional militaries do.

But no amount of adaptation can eliminate civilian harm in major urban combat. That is not a moral failure. It is the nature of war in cities. History proves this at scale. When American forces fought to liberate the Philippines’ Manila in 1945, the battle became one of the most destructive urban fights of World War II. Over four weeks of combat, approximately 100,000 civilians were killed alongside roughly 17,000 Japanese defenders. Thousands of American and Allied civilians were held as internees, along with prisoners of war, inside the city. The devastation was immense. Yet no serious legal or historical analysis frames the United States as having committed genocide in Manila. The intent was not to destroy the Filipino people. It was to defeat an enemy that turned a city into a fortress and carried out systematic atrocities against civilians. Civilian death, however tragic, did not redefine lawful military necessity as criminal intent then, and it cannot be allowed to do so now.

The Korean War underscores the same point even more starkly. Roughly 2 million North and South Korean civilians were killed over 37 months of war. If the same statistical logic now applied to Gaza were imposed retroactively, stripped of context about who died, how they died, and who killed them, that figure would translate into more than 54,000 civilian deaths every single month. Yet the Korean War is understood, correctly, as a lawful collective defense against invasion, not as a genocide.

This is what happens when the laws of armed conflict are replaced by statistical absolutism. Law becomes a tool of political warfare. Legal terms become slogans. The side that fights lawfully becomes uniquely vulnerable, judged not by intent or conduct, but by the inevitable suffering that accompanies urban combat.

When civilian suffering becomes the decisive weapon, advantage flows to those who want civilians to suffer. If accusation and optics define legality, the optimal strategy is to embed among civilians, prevent evacuation, fight from protected sites, and manipulate information so that every death becomes ammunition. That is not the protection of civilians. It is the exploitation of them.

If this logic becomes the standard, the result will not be fewer civilian deaths. It will be more. The new standard by which Israel “committed genocide” in Gaza will validate hostage taking, the use of human shields, the engineering of humanitarian crises, and the manipulation of casualty figures as weapons. It will tell future adversaries that the fastest way to defeat a democratic military is not to fight it, but to endanger civilians until the defender is condemned for trying to stop the violence. In that world, urban areas become more lethal, not less. Civilians become more vulnerable, not more protected.

The implications for the United States military are direct and dire. Every serious contingency in the Pentagon’s war-planning scenarios involves dense urban terrain. Defending Seoul, Taipei, or NATO’s eastern flank means fighting in cities where civilians cannot be separated from the battlefield and where adversaries are trained to exploit information and lawfare as much as maneuvers and firepower. If civilian harm alone becomes proof of criminality, democratic militaries face an impossible choice: Fight and be condemned, or refrain and concede defeat.

Accusations of genocide being leveled against Israel do not merely constitute baseless defamation of an ally, as I have personally seen with my own eyes during six research trips to Gaza over the course of the war. It is a weapon aimed at lawful self-defense. The tragedy of civilian suffering in war is real. It should never be denied. But turning tragedy into a legal verdict without proof of intent is not moral progress. It is paralysis.

If baseless slander becomes law, lawful self-defense becomes impossible. And if lawful self-defense becomes impossible, democracies will have lost the next wars before they begin.
