Unlawful Orders, Lawful Refusals: When Soldiers Say No

One of the more persistent myths about the military—American or otherwise—is that it runs on blind obedience. Orders come down, and they are followed. Full stop. Reality is less convenient, and far more interesting. Modern military law, particularly in the United States, is built on a different premise: obedience is required, but only to lawful orders. The moment an order crosses into illegality, the duty flips. A soldier is not only permitted to refuse—it is expected.

This is not moral philosophy dressed up in uniform; it is black-letter law.

Under the Uniform Code of Military Justice (UCMJ), service members are obligated to obey lawful orders, but they are equally bound to disobey orders that are manifestly unlawful. This principle was sharpened in the aftermath of the Nuremberg Trials, where “just following orders” was decisively rejected as a defence for war crimes. That legacy runs directly through American military doctrine today.

The Evidence: Disobedience Is Not Theoretical

There is, in fact, concrete evidence of American troops refusing unlawful orders—though such cases are less celebrated than battlefield heroics.

One of the most cited examples comes from the Iraq War. In 2004, Army Specialist Camilo Mejía publicly refused to return to combat duty, arguing that the war itself and certain conduct within it violated both domestic and international law. While Mejía was ultimately court-martialed, his case opened a wider debate about the legality of orders in controversial conflicts.

More directly tied to battlefield conduct are incidents surrounding detainee abuse. Following the revelations at Abu Ghraib prison, several soldiers testified that they were uncomfortable with, and in some cases resisted, abusive interrogation practices. The scandal demonstrated both sides of the coin: some personnel complied with unlawful orders, while others questioned or resisted them—often at personal risk.

Going further back, during the Vietnam War, the My Lai Massacre stands as a grim illustration of what happens when unlawful orders are obeyed. Yet even there, dissent existed. Warrant Officer Hugh Thompson intervened mid-atrocity, placing his helicopter between U.S. troops and Vietnamese civilians and threatening to fire on fellow Americans if the হত্য continued. His actions remain one of the clearest examples of refusing an unlawful order in real time.

These cases establish a pattern: refusal happens, but it is uneven, often costly, and rarely institutionally comfortable.

The Legal Standard: What Counts as “Unlawful”?

The key phrase in all of this is “manifestly unlawful.” Soldiers are not expected to second-guess every command through a legal microscope. However, certain categories are unmistakable:

Orders to target civilians Orders to torture or abuse detainees Orders that violate the laws of armed conflict

In such cases, the illegality is presumed to be obvious. The duty to disobey becomes active.

The difficulty lies in the grey zones—where legality is contested, classified, or politically charged. That is where institutional pressure often outweighs individual judgment.

War Powers and the Question of Iran

This brings us to the second limb of the argument: the legality of initiating hostilities.

The War Powers Resolution was designed to constrain unilateral presidential military action. It requires the President to obtain congressional authorisation or, failing that, to limit military engagement to a short window (typically 60–90 days) before withdrawing forces.

The critical point—often obscured by semantics—is that the law does not hinge on what the executive branch calls the operation. Whether it is labelled a “war,” “military action,” or “kinetic engagement,” the legal test is substantive:

Are U.S. forces engaged in hostilities? Is there a risk of sustained combat?

If the answer is yes, the War Powers framework is triggered.

In the context of a hypothetical or emerging conflict with Iran, the absence of explicit congressional approval raises a serious constitutional question. The executive may argue necessity, self-defence, or limited scope, but those arguments do not nullify the statutory requirement.

Does This Make Orders Unlawful?

Here is where the analysis tightens.

Even if a war is arguably initiated without proper congressional authorisation, it does not automatically follow that every order given within that conflict is unlawful in the sense required for disobedience.

This distinction is crucial:

Strategic illegality (e.g., questionable compliance with the War Powers Resolution) operates at the level of constitutional and political accountability. Tactical illegality (e.g., ordering the killing of civilians) operates at the level of individual criminal responsibility.

A soldier on the ground is generally not in a position—legally or practically—to refuse deployment on the basis that Congress did not authorise the conflict. Courts have historically been reluctant to allow such challenges from service members.

However, if within that conflict an order is given that clearly violates the laws of armed conflict, the duty to refuse remains intact—regardless of the broader legality of the war itself.

The Uncomfortable Truth

The system is designed to split responsibility:

Political leaders bear responsibility for whether a war is fought. Military personnel bear responsibility for how it is fought.

This division is tidy in theory and messy in practice. It explains why unlawful wars can still produce lawful orders, and why lawful wars can still produce war crimes.

Conclusion

There is ample evidence that American troops have disobeyed unlawful orders. But those moments are exceptions carved out under pressure, not the default setting of military life. The legal framework demands moral courage, yet the institutional environment often punishes it.

As for conflicts initiated without clear congressional approval, the War Powers question is real and unresolved. But it operates on a different plane from the battlefield obligation to refuse unlawful commands.

In short: a soldier is not a robot—but neither is he a constitutional court.

And that tension is not a bug in the system. It is the system.
