Nournews: In recent days, some U.S. officials have advanced a quasi-legal argument to justify the possibility of striking Iran's energy infrastructure. At first glance, this reasoning appears to be grounded in international law. The argument is that because energy infrastructure supports a country's economy, and the economy in turn sustains military capability, such facilities may be classified as "war-supporting objectives."

At first glance, this reasoning may seem plausible to some. Yet the real issue is not Iran, nor even a particular refinery or gas field. The issue is a subtle but profound shift in the philosophy of the law of armed conflict. If this interpretation becomes accepted practice, the definition of a "military objective" could expand so broadly that it would encompass nearly every vital installation within a society. This is precisely where the discussion moves beyond a purely legal debate and becomes a strategic question: Is what the United States is now advancing merely a new interpretation of existing legal provisions, or is it an attempt to rewrite and fundamentally transform the rules governing war?

International humanitarian law is founded on the principle of limiting warfare, not expanding it. The philosophy underlying the Geneva Conventions and customary laws of armed conflict seeks to preserve a clear distinction between civilian society and legitimate military objectives, even during hostilities. The principles of distinction, proportionality, and military necessity form the three pillars of this legal framework. Their purpose is straightforward: to prevent war from engulfing society as a whole. An expansive interpretation of "war-supporting objectives" runs directly counter to this philosophy.

If a mere economic connection to a state's defense capability is sufficient to justify an attack, no meaningful boundary remains. A refinery becomes a legitimate target because it generates revenue. By the same logic, power plants would qualify as targets. Why, then, should water supply networks, ports, railways, steel factories, data centers, banking systems, telecommunications infrastructure, or even food production facilities be excluded? All of these contribute, in one way or another, to a country's economic and administrative continuity, and every economy inevitably allocates a portion of its resources to national defense. The logical consequence of this argument is the collapse of the principle of distinction.

What is emerging in Washington's rhetoric and policy is a dangerous shift in the legal language of war. In the past, major powers often resorted to military action first and sought legal justification afterward. Today, the process appears to be reversing: legal concepts are redefined in advance to broaden the scope of military action. This is what some legal scholars describe as the "legalization of war"—not because war itself has become more lawful, but because legal terminology is increasingly employed to normalize and justify wider forms of violence.

This development is far more than a theoretical concern. The experience of the past two decades demonstrates how concepts such as "preemptive self-defense," "preventive self-defense," the "global war on terror," and expansive interpretations of "military necessity" have gradually moved from exceptional doctrines toward accepted practice. There is now concern that the concept of a "war-supporting objective" may follow the same trajectory. If interpreted without clear limits, it could evolve from a narrow exception into a blanket justification for attacking the essential lifelines of civilian societies.

From a legal standpoint, such an expansion is highly questionable. International humanitarian law distinguishes between making a direct and effective contribution to military action and merely playing a general role in a nation's economy. The fact that an industry's revenues ultimately contribute to the state's general budget does not, by itself, transform that industry into a military objective. Were that reasoning accepted, virtually no economic activity anywhere in the world would remain beyond the reach of legitimate military targeting. Such an interpretation would turn the concept of a "military objective" from a limiting criterion into a mechanism for eliminating the very limits it was designed to impose.

Moreover, energy infrastructure is far more than an economic asset; it is fundamental to the functioning of society. Hospitals, water treatment systems, public transportation, pharmaceutical supply chains, communications networks, food production and storage, and dozens of other essential services all depend upon it. Striking such facilities is not simply an attack on a state's economic capacity—it predictably inflicts severe humanitarian consequences upon millions of civilians. For this reason, even where disagreement exists over whether a target is military in nature, the principles of proportionality and precaution continue to impose strict constraints on the use of force.

Perhaps the most important question concerns the future of the international legal order. If it is accepted today that any critical infrastructure may become a legitimate military target because of its economic function, that precedent will not remain confined to a single country. The same reasoning invoked today regarding a refinery in Iran's Asaluyeh could tomorrow be applied to energy transmission lines in Europe, gas terminals in Asia, or electrical grids anywhere else in the world. Once legal rules are expanded, they are no longer constrained by geography.

In the decades following the Second World War, the international community worked to establish legal rules designed to prevent warfare from consuming entire societies. Today, the danger is that these achievements may erode—not through formal declarations, but through the gradual redefinition of legal concepts. Wars do not always begin with missiles; sometimes the first shot is fired in the language of law, where words slowly lose their original meaning and exceptions, almost unnoticed, become the rule.

From this perspective, the issue extends far beyond the security of a single refinery or gas field. What is ultimately at stake is the preservation of the delicate legal boundary that separates military objectives from civilian society. If that boundary collapses, war will no longer remain confined to armies—it will engulf entire societies. Perhaps the greatest responsibility of international law in the twenty-first century is not to devise new legal vocabulary to justify war, but to prevent the language of law from becoming an instrument for expanding the battlefield itself.
