Two enemies stand accused
Two enemies stand accused. A single United Nations report, released on 17 September, has found reasonable grounds to believe the United States committed war crimes and that the Islamic Republic of Iran committed crimes against humanity. This is a deeply unusual document. It is rare for a single UN mission to issue such grave findings against two rival states simultaneously, a move that sets the stage for an exceptionally complex and hostile diplomatic period. One is accused of war crimes. The other, crimes against humanity. Both are condemned. The accusations are distinct but politically inseparable, a pair of findings that will satisfy neither Washington nor Tehran and will give ammunition to both. The report was compiled by a fact finding mission of human rights experts. They were commissioned by the United Nations itself. Their conclusions are now public record.
The mission focused part of its work on American actions from this February. Investigators pointed to specific deadly strikes, one on a primary school in the city of Minab and another on a sports complex in Lamerd. The United States has said nothing. Washington has never acknowledged carrying out the attacks at all, maintaining a determined public silence that now sits in direct opposition to the UN's formal conclusions about its conduct. This silence is now a political fact in itself. At the same time, the mission’s remit was wider. Its experts scrutinised the conduct of the Iranian authorities during a recent wave of popular protest. They documented a brutal crackdown by the government. The report concludes this suppression was so systematic that it amounted to crimes against humanity. A war on its own people.
The report lands in an arena of profound hostility. The US and Iran are locked in a shadow conflict across the Middle East, a struggle fought with proxies, sanctions, and unacknowledged military operations. Now the language of international law has entered the fight. It has no immediate teeth. It cannot compel arrests. It cannot force a trial. Its political weight, however, is immense, providing a formal, UN sanctioned narrative that both countries will find almost impossible to ignore and equally difficult to manage. Diplomacy will become more difficult. The accusations give each side a powerful tool to wield against the other on the world stage, a way to claim moral high ground while deflecting from their own alleged crimes. The battle is for reputation.
The letter of the law
The mission itself operated on a precise legal and procedural footing. It was not a court. Its members were not judges. They were human rights experts, investigators given a mandate directly from the United Nations to establish a factual record of events in Iran. Their task was to gather evidence, to analyse it against the standards of international law, and to produce findings, which is why the language of their final report is so specific and so carefully partitioned between the two accused states. These are not broad condemnations. They are specific allegations. Each is rooted in a separate body of law.
The two central accusations are distinct for a reason. They are not interchangeable. The mission’s experts concluded there were 'reasonable grounds' to believe the United States committed war crimes, a charge specifically tied to the conduct of hostilities between warring parties. This finding relates directly to the February strikes on a school in Minab and a sports complex in Lamerd, actions viewed by investigators as part of an armed conflict. The accusation against Tehran is different. It is a crime against humanity. This finding is not about a military engagement with another country, but about the Iranian authorities' own actions against their own people during a brutal crackdown on internal dissent and protest. One charge governs the battlefield. The other governs a state’s treatment of its civilians.
This careful legal language is critical. The report does not declare anyone guilty. The phrase 'reasonable grounds' is the vocabulary of an investigator, not a prosecutor delivering a closing argument in a courtroom. It signifies that the experts, having reviewed the available information, believe a sufficient evidentiary threshold has been met to warrant the conclusion that a crime was likely committed. It is a formal finding. It shifts the burden of response. The conclusion provides a basis for other bodies, from the UN Security Council to individual national governments, to consider their own next steps, whether diplomatic censure, sanctions, or further legal action. It is the start of a process. Not the end. The facts are now on the table.
The strikes Washington denies
The American position is one of official silence. No comment. The Pentagon has offered no statement on the February strikes. The White House has said nothing. This silence is a policy. The United States has not acknowledged carrying out the attacks on a primary school in Minab and a sports complex in Lamerd which the UN mission has now placed at the centre of its war crimes allegation. It is a vacuum of information that allows for deniability, a strategic ambiguity that has long defined the undeclared hostilities between Washington and Tehran. The facts on the ground are disputed because one side refuses to speak about them.
This is not a new war. It is an old one. It is a shadow war. For years, the two countries have engaged in a cycle of covert action and retaliation, a conflict played out in the shipping lanes of the Persian Gulf, on the servers of critical infrastructure and through proxies across the wider Middle East. Admitting to a specific operation, especially one that resulted in civilian casualties at a school, would drag a single clandestine event into the formal light of international law and diplomacy. Silence is safer. It has been the default posture for both sides in a conflict where claiming responsibility for an attack is often seen as less advantageous than allowing an opponent to guess.
The UN report changes that calculation. It shatters the quiet. The experts have broken the ambiguity by publicly attributing the strikes and attaching the grave charge of a war crime, forcing an issue that Washington would have preferred to keep buried. The question of what happened in Minab and Lamerd is no longer just a matter for intelligence agencies and covert operators. It is on the public record. It is in a UN document. The report transforms the strategic silence from a tool of statecraft into what looks, to the rest of the world, very much like an admission of guilt. The pressure to respond will now build. It will build in Washington. It will build among America's allies. The silence cannot hold.
Tehran's war on its people
The UN mission did not only target Washington. Its focus was twofold. The report’s second and equally grave finding accuses the Iranian authorities themselves. Not of war crimes, but of crimes against humanity. This is a crucial legal distinction, a charge reserved for the most egregious, widespread or systematic attacks directed against any civilian population. The target was Iran’s own people. The crackdown on recent protests was, according to the UN’s experts, a campaign of state organised violence so severe it crossed a legal and moral threshold.
The protests themselves are described only as ‘recent’ in the mission's public summary. Their specific cause is not detailed. But the pattern is familiar. For years, Iran has been subject to waves of popular unrest, driven by economic collapse, anger at social restrictions, and a deep frustration with the clerical establishment that has ruled since 1979. Tehran’s response is also familiar. It is reliably brutal. The state has consistently treated domestic dissent not as a political problem to be managed but as an existential security threat to be crushed, often deploying the Islamic Revolutionary Guard Corps to suppress demonstrations with lethal force.
This is Tehran’s war at home. A conflict on its own streets. By formally labelling the crackdown a crime against humanity, the United Nations moves beyond vague condemnations of human rights abuses and into the realm of specific international law. The charge matters. It implies a deliberate policy enacted from the very top of the Iranian state. It transforms disparate acts of repression, the beatings, the arrests, the killings, into components of a single overarching and criminal plan directed against civilians. This provides a legal foundation for future sanctions, diplomatic isolation and perhaps one day prosecutions should any of Iran’s leaders ever find themselves before an international court. It directly refutes Tehran's consistent narrative that it is merely maintaining order against foreign backed rioters. The UN says the order itself is the crime.
A court with no defendants
The report carries no immediate legal weight. No court can enforce it. No international prosecutor can compel an American general or an Iranian minister to stand trial based on these findings alone. This is a dead end. The reason is jurisdiction, a brutal reality of international law which dictates that great powers, and those who defy them, often operate beyond the reach of any tribunal in The Hague. Neither Washington nor Tehran accepts the authority of the International Criminal Court, the world’s permanent tribunal for such offences. While the United Nations Security Council could theoretically refer a situation to the court, the United States holds a veto. It will block any case against itself. The path to legal justice is closed before it even opens.
So the report seems powerless. It is not. Its true power is political, not judicial, and its consequences will be measured in diplomatic capital and economic pain rather than prison sentences. The findings provide a formal, UN stamped vocabulary for condemnation, giving nations a new justification to isolate and sanction both countries. It offers a playbook for their rivals. The charge of crimes against humanity provides European capitals with a solid basis for expanding sanctions on Iran, shifting pressure beyond the nuclear file and onto the regime’s treatment of its own citizens. It hardens the lines. It makes any future rapprochement much more difficult.
For the United States, the damage is reputational. Deeply so. The war crime accusation, related to the strikes on a school in Minab and a sports complex in Lamerd which Washington has not even acknowledged, gives adversaries like Russia and China a potent counterargument every time the US raises human rights. It poisons the well. It complicates alliances. This is where the real battle over the report will be fought, not in a courtroom with black robes and gavels but in the corridors of the UN in New York, in the wording of trade deals, and in the strategic calculations of foreign ministries from Beijing to Berlin. The document is not a verdict. It is ammunition. And all sides will now use it.
Law becomes a weapon
This is lawfare. It is a very modern war. The theatre of operations is not a battlefield but the institutions built to prevent conflict, including human rights organisations and international courts. The ammunition is not bullets but legal arguments, fact finding missions and formal reports. This is a competition for legitimacy itself.
The process transforms the architecture of international justice into a weapon. A UN report becomes a tool for leverage. A legal finding is used to isolate a rival. It has become a central part of statecraft for powers great and small, a way to pursue strategic aims by non military means. The UN mission’s findings, which accuse both the United States of war crimes and Iran of crimes against humanity, provide a stark illustration of this global shift where legal reports are weaponised by states to damage rivals on the international stage. Both Washington and Tehran now hold a UN sanctioned instrument they can use to attack the other’s credibility. Both are also exposed.
The goal is not necessarily a conviction in court, which is often impossible. The objective is political. It is about controlling the narrative. Every time American diplomats criticise another nation’s human rights record, those states will now be able to point to a formal UN document alleging US war crimes over the strikes in Minab and Lamerd. It becomes a permanent and powerful rebuttal. The accusation becomes the point. In the same way, the charge of crimes against humanity will be used by Iran’s opponents to justify tougher sanctions and deeper diplomatic isolation, framing the regime as fundamentally illegitimate. The law becomes a justification for punishment. The systems created to hold power to account are themselves becoming instruments of power. Justice is now a battlefield.
