The Truth: There Is No Such Thing As the International Law of War

This article argues that what people call an international law of war is really a set of contested norms, not a universal legal code, and it examines how ethical traditions, postwar agreements, and asymmetric enemies interact with American rules of engagement while challenging narratives that portray U.S. actions as uniquely unlawful.

Myths about universal constraints on warfare keep coming back into public debate, often driven by coordinated media pushes that shape perception more than policy. These narratives tend to simplify complex moral and legal questions into catchy claims about right and wrong, and they steer attention away from deeper realities that matter for national defense and public safety. Understanding the limits of any so-called international law of war helps clear away rhetorical fog and better frames the debate about when force is justified.

Some recent examples show how public empathy can be shaped to favor a particular image of a person or incident, even when that image omits crucial facts. The tendency to canonize certain actors and condemn others is less about consistent moral principle than about influence and messaging. That pattern is visible in how commentators interpret incidents involving national security, law enforcement, and border defense.

The phrase law of war suggests a single, enforceable legal code that binds all combatants at all times, but that is not the practical reality. What exists in practice are norms, customs, treaties that apply best to uniformed state militaries, and different groups choose whether to follow them. Insurgent groups, criminal syndicates, and nonstate actors frequently adopt rules of conduct that diverge sharply from the constraints accepted by democracies.

Most people raised in liberal republics forget that power relations shape behavior in many parts of the world, where the strongest faction typically enforces its will. Representative government and the rule of law are exceptions that require broad consent and shared restraint to function. When adversaries have no such constraints, they exploit the moral and legal self-limits of democracies to their advantage.

Popular sayings capture this tension: “all’s fair in love and war” gets at raw realism, and Civil War era general William Tecumseh Sherman put it bluntly: “War is cruelty, and you cannot refine it.” Those lines remind us that war’s inherent brutality resists tidy moralization, yet societies attempt to civilize conflict through ethical traditions and legal frameworks. Those efforts are valuable but imperfect and often one-sided in their practical reach.

One important influence on modern thinking about armed conflict is Christian Just War Tradition, which pushes for strict moral criteria about when and how force may be used. That tradition informed the Geneva Conventions after World War II, agreements primarily intended to regulate clashes between regular state militaries. Those treaties created expectations and obligations among signatories, but their scope and enforcement mechanisms leave gaps when conflict involves irregular or criminal actors.

The drafters of postwar agreements could not realistically bind groups such as the Taliban, ISIS, Haqqani Network, or transnational drug cartels, all of which have shown willingness to pursue any means necessary for their aims. When an adversary treats brutality as a tactic and ignores restraints, the party seeking to defend itself faces agonizing choices about how much to self-limit without inviting greater harm. That asymmetry shapes much of the frustration about perceived double standards in the application of norms.

Any claim that the United States uniquely violates a universal law of war requires asking what authority defines that law and who enforces it. Domestic American law governs American forces and is created through our constitutional processes, while international norms are often the result of negotiated treaties among states, not global fiat. There is no single, superior global legislature that issues universally binding battlefield laws for all combatants across history and circumstance.

Retired officers and critics who denounce particular uses of force sometimes have complicated histories with past operations that were broader and more enduring than the limited strikes they now reject. Changing views about tactical choices can reflect evolving judgment, but they also raise questions about consistency and the standards applied across different conflicts. Context matters when evaluating whether a strike meets moral and legal thresholds.

Domestic law forbids bringing deadly narcotics into the country, and actions that raise the risk for those smuggling lethal drugs can alter the calculus of criminal enterprise. Making smuggling more dangerous can deter activity that threatens communities, and applying force against that threat is framed here as legitimate defense of the nation. In that light, there is no coherent, enforceable international law of war that binds every actor equally in every circumstance, and policy debates should account for that asymmetry when judging American conduct.
