The Trump administration has launched Operation Epic Fury, a massive bombing campaign against Iran that has already struck over 12,300 targets as of late March 2026, including the B-1 bridge near Tehran and plans to hit more bridges in what Trump has called bombing Iran “back to the stone ages.” Meanwhile, Ukraine’s military has been explicitly blocked by Western allies from using American, German, and Italian weapons to strike similar bridge targets inside Russia—even though Ukraine is conducting a defensive war against an invading force. The disparity raises a fundamental question about how international law, military doctrine, and alliance politics actually work in modern warfare. The answer reveals less about objective legal principles and more about geopolitical power, the sovereignty of military decision-making, and how the same acts are justified or forbidden depending on who conducts them.
The core issue is not that bombing bridges is illegal in principle—it isn’t. Bridges become legitimate military targets when they actively support military operations. Rather, the difference stems from three distinct factors: first, the US operates as an independent military power with no restrictions from allies on its targeting decisions; second, Ukraine must use Western-supplied weapons and operates under explicit conditions imposed by those allies; and third, the legal justifications offered for each campaign reveal a troubling inconsistency in how military actions are evaluated. This article examines the facts of both operations, the actual international law governing military infrastructure, and the geopolitical realities that explain why identical tactics are treated completely differently depending on who executes them.

What is the Legal Status of Bridges as Military Targets?
Under international humanitarian law, bridges are classified as civilian objects—meaning they have no inherent military value. However, civilian objects become legitimate military targets when they make an “effective contribution to military action” and their destruction offers a “definite military advantage.” The critical question is not whether a bridge can be bombed, but whether it qualifies as a military objective at the specific moment it is struck.
Ukraine’s Security Service claimed the Crimean Bridge—which it attacked in June 2025 using underwater explosives—was a “completely legitimate target” because Russia uses it “as a logistical artery to supply its troops.” This argument applies the same principle to the bridge that the US appears to be applying to Iranian bridges. Kerch Strait Bridge attacks did not violate international law according to legal analysis, precisely because the bridge was functioning as critical military infrastructure. The distinction principle in humanitarian law does not forbid such attacks; it requires that the attacker distinguish between military and civilian objectives and that any civilian harm be proportional to the military advantage gained.
How Has the Trump Administration Justified Bombing Civilian Infrastructure in Iran?
The Trump administration has explicitly threatened to target Iran’s civilian power infrastructure and other non-military targets—not just military or dual-use bridges. Trump stated he plans to hit Iran “extremely hard” over the next 2-3 weeks to complete Operation Epic Fury, with public statements about bombing civilian power plants specifically. The B-1 bridge strike near Tehran killed 8 people and wounded 95 according to Iranian state media, demonstrating that these strikes carry significant civilian casualties. International law experts have directly stated that bombing civilian power infrastructure constitutes potential war crimes under international humanitarian law.
The proportionality requirement demands that anticipated military advantage justify the civilian harm caused. Destroying civilian power plants that heat homes, power hospitals, and support civilian life cannot easily be justified as proportional to any plausible military advantage, unless the administration’s position is that destroying Iran’s civilian economy is itself a valid military objective. The threatened campaign to bomb Iran “back to the stone ages” explicitly targets the civilian foundation of society, not military objectives. However, because the US is not bound by ally-imposed restrictions—as Ukraine is—these decisions remain entirely within American military command authority, constrained only by international law principles that lack enforcement mechanisms against major powers.
What Are the Western Restrictions on Ukraine’s Weapon Use?
The Western restrictions on Ukraine are explicit and unambiguous. Italian Foreign Minister Tajani stated that Ukraine should only use Italian-supplied weapons within Ukrainian territory—not inside Russia. German Chancellor Scholz stated there is “no reason” to lift Western restrictions on Ukraine’s use of Western weapons to strike inside Russia. These are not legal interpretations of international law; they are political conditions imposed by military suppliers as terms for providing weapons.
The practical effect is that Ukraine can bomb Russian bridges when those bridges are located in occupied Ukrainian territory or when struck by Ukrainian-manufactured weapons, but cannot use American or German-supplied long-range precision weapons for the same purpose inside Russia proper. Ukraine’s previous Crimean Bridge attacks—which were successful and internationally recognized as legitimate military action—could only be executed using Ukrainian methods and weapons systems. The restriction creates a perverse incentive structure: Ukraine can strike certain targets if it develops its own weapons, but loses access to Western precision systems specifically because it wants to strike those same targets. Meanwhile, the US faces no such restrictions from allies, because no NATO ally could impose conditions on American military operations without fundamentally breaking the alliance.
How Does International Law Actually Apply to Both Campaigns?
International humanitarian law applies equally to American military operations and Ukrainian military operations—in theory. The law does not change based on which country executes a bombing campaign. However, enforcement mechanisms are entirely absent. The International Criminal Court has no jurisdiction over American military operations because the US is not a party to the ICC statute. American military personnel and officials are protected from prosecution through bilateral immunity agreements with nearly every country.
Ukraine, by contrast, could theoretically be subject to ICC investigation, and its military operations are scrutinized internationally. This asymmetry creates a situation where the same legal standard produces different practical consequences. If striking civilian power infrastructure violates the proportionality requirement in humanitarian law, it violates that requirement whether the US or Ukraine does it. But only Ukraine faces real accountability mechanisms, while the US enjoys practical immunity. The Western restrictions on Ukraine are therefore partially justified as legal safeguards—preventing Ukraine from crossing legal lines that the US crosses without consequence—but they are also partially expressions of geopolitical control, ensuring that a smaller ally does not conduct military operations that might provoke escalation that primarily affects American interests.
The Double Standard in How Military Targeting Rules Are Applied
The inconsistency becomes stark when comparing public justifications. Trump’s campaign targets civilian power infrastructure explicitly and openly, framing it as appropriate punishment for Iran. The administration has not claimed that civilian power plants are military objectives; it has claimed that destroying civilian capacity is a valid strategic goal. Meanwhile, Ukraine’s targeting of the Crimean Bridge—which actually is a military infrastructure asset, not a civilian power plant—must be justified as a proportional response to Russian military use, because Ukraine faces Western and international scrutiny that the US does not.
Germany, Italy, and other allies argue they are preventing Ukraine from escalating the conflict or drawing NATO into direct confrontation with Russia. This is partially true, but it also reflects asymmetric constraint: the same allies would not attempt to restrict American military operations in Iran, regardless of their scope or civilian impact. Ukraine has less political leverage with Western governments than the US does, even though Ukraine is the invaded party defending its territory while America is the attacker initiating a new conflict. The restriction is presented as legal caution but operates as political control, preventing the smaller ally from conducting operations that might complicate American strategy or NATO calculations.
Why Do Allies Enforce These Restrictions Specifically on Ukraine?
Germany, Italy, and other Western allies imposed restrictions on Ukraine weapon use partly to prevent escalation with Russia, partly to retain influence over the conflict’s trajectory, and partly because they export weapons to smaller nations but cannot control American military decisions. Germany’s reluctance to allow ATACMS or long-range strikes reflects German concern that such strikes might provoke Russian nuclear threats or direct NATO involvement. Italy’s restrictions reflect a broader European position that the conflict should eventually be negotiated, not won militarily—an assumption that does not apply to American policy toward Iran. However, there is no technical reason these restrictions exist.
Ukraine could conduct the same bridge strikes using its own domestically produced weapons systems, as it did with the Crimean Bridge. The restrictions are purely political leverage. By conditioning weapon supply on targeting restrictions, Western allies maintain de facto veto power over Ukrainian military strategy. The US has never accepted such conditions from allies, and no ally has ever attempted to impose them. This reveals that the restriction framework reflects not legal necessity but power imbalance—the ability of wealthy allies to dictate military strategy to a smaller dependent nation.
What This Reveals About International Military Law in Practice
The Iran and Ukraine cases demonstrate that international humanitarian law is a framework with no enforcement mechanism against major powers. The US can bomb civilian infrastructure, threaten to destroy civilian power plants, and cause civilian casualties because no institution has the power or willingness to hold American military decision-makers accountable. Ukraine must justify every strike as proportional and necessary because smaller nations lack this immunity. The legal standard is the same, but the practical application is entirely different.
This pattern will persist because international law at the enforcement level is fundamentally based on power. Nations with sufficient military and economic influence can interpret humanitarian law loosely, while smaller nations must interpret it strictly because they face real consequences for violations. The restrictions on Ukraine are partially justifiable as prudent legal caution but also function as a mechanism of control. As international conflicts continue, this asymmetry will shape which nations can conduct military operations freely and which nations must seek permission from allies—with implications for which nations can actually defend themselves effectively against larger adversaries.
Conclusion
The Trump administration’s Operation Epic Fury and Ukraine’s defense against Russian invasion represent not a legal inconsistency but a political one. International law does not forbid bombing bridges used for military supply, nor does it clearly forbid all strikes on civilian infrastructure—though it does require proportionality that many current operations exceed. The actual difference is that the US operates with effective immunity from international accountability while Ukraine operates under explicit restrictions imposed by military suppliers and political allies.
These restrictions are presented as legal safeguards but function as political controls, preventing the invaded nation from conducting military operations that a larger military power conducts freely. The resolution is not to eliminate restrictions on Ukraine—which in some cases reflect legitimate concerns about escalation—but to acknowledge that these rules reflect power differentials, not objective legal principles. International law is equally applicable to all military operations in theory but enforced unequally in practice. Until major military powers accept the same accountability mechanisms they demand from smaller nations, or until enforcement mechanisms are strengthened against all actors equally, the apparent double standard will persist: larger powers will determine which actions are justified, while smaller powers will be constrained by that same justification framework applied selectively.
