There is a certain type of British parliamentarian for whom the world is not a complex web of shifting allegiances and existential threats, but a neatly ruled jurisdictional straightjacket for the West. To hear Emily Thornberry or the leadership of the Green Party tell it, the recent US and Israeli operations against the Iranian regime are not a necessary excision of a regional cancer, but a simple “breach of international law.” Case closed. Bring in the tea.
The legal case for action against Iran is not merely “arguable”; it is compelling
One expects this kind of reductionism from the protest lines, but it is deeply unsettling to see it calcify into the official posture of a British government. We have reached a bizarre juncture where Whitehall appears to have adopted a black-and-white interpretation of international law that slants so heavily against national freedom of action that it borders on the masochistic.
For centuries, British law was held up as the global paragon – a pragmatic, evolving system that balanced order with the messy reality of human affairs. Yet this government seemingly no longer believes in that legacy. Instead, they treat the UN Charter, and other branches of the international legal apparatus, not as a living contestable framework, but as a suicide pact designed to ensure Western democracies remain politely motionless while their enemies sharpen the blade.
International law is not some static, crystalline structure handed down from Sinai. Indeed, it is formed by the practice of states. If the law is interpreted in a way that always leaves the law-abiding defenceless against the law-breaker, then the law is not just “flawed” – it is worse than useless. Other liberal democracies, such as Australia and Canada, have looked at the same facts and reached the opposite conclusion about “Operation Epic Fury.” They understand what our own Foreign Office seems to have forgotten: that nuance is not a loophole; it is a necessity.
The legal case for action against Iran is not merely “arguable”; it is compelling, both within and without the strictures of the UN Charter.
First, there is the reality of the “Long War.” Since the Ayatollah’s 1979 proclamation of “Death to America,” Iran has been in a state of constant, if unconventional, armed conflict with the West. A state of war does not vanish because there is a temporary lull in the counting of bodies. Through its proxies – Hezbollah, Hamas, the Houthis – Tehran has waged a persistent campaign of kinetic aggression. When President Trump listed the decades of attacks, from the 1983 Beirut barracks bombing to the strikes on global shipping, he wasn’t just reminiscing; he was identifying a continuous theatre of operations. British lives lost to Iranian IEDs in Iraq furnish further such sad evidence, as do the many attempted terrorist attacks on our soil, which the Prime Minister referenced. If a conflict is established, the use of force is governed by the laws of war – distinction and proportionality – not the peacetime hurdles of Article 51.
Second, we must address the ticking clock of the Iranian “bomb.” The doctrine of self-defence, under Article 51 of the United Nations Charter, includes the right to pre-empt an imminent and catastrophic threat. To suggest that the US and Israel must wait for a mushroom cloud to appear over Tel Aviv before the law “allows” them to act is a form of legalistic insanity. Negotiations with a regime that views diplomacy as a stalling tactic for enrichment are not a legal barrier to action once it is clear those negotiations have failed.
Finally, there is the moral and legal weight of humanitarian intervention as established in customary law and statecraft. We have seen this before: in Liberia, in the no-fly zones of Iraq, and in Kosovo. In 1999, Tony Blair stood in Chicago and argued that Western democracies have a responsibility to intervene against oppressive regimes. The Iranian people, who have been tortured, slaughtered, and repressed for decades, represent the ultimate “humanitarian distress.”
To hide behind a narrow, 1945-era reading of the UN Charter while a regime exports terror and murders its own children is not “upholding the rule of law.” It is moral cowardice dressed up as jurisprudence. The Prime Minister’s recent, dizzying U-turn on the use of British sovereign bases –previously described by Whitehall as a legal impossibility – has let the cat out of the bag. It confirms that what was presented as “inviolable international law” was, in fact, nothing more than political sophistry designed to delay the inevitable.
It is moral cowardice dressed up as jurisprudence
The US/Israeli action is both morally justified and legally legitimate. Sir Keir Starmer will continue to face a series of choices: He can continue to play the role of the cautious clerk, clutching a dusty rulebook while the world burns, or he can finally inhabit the role of a statesman and a true upholder of human rights. This demands more than a reluctant nod; it requires: an explicit acknowledgement that the Iranian regime is an existential evil. Unreserved diplomatic and strategic support for our primary allies. A forceful presentation of this posture as Britain’s only viable path, rather than a series of graceless concessions to incremental pressure.
International law was designed to protect the civilised world, not to serve as a set of handcuffs for those tasked with defending it. If our legal frameworks truly forbade us from stopping a genocidal, nuclear-aspirant theocracy, then it would be the law – and not the action – that was fundamentally broken. Fortunately, the law is far more robust than the anaemic interpretations currently favoured by the high priests of paralysis in Whitehall. It bestows clear legitimacy on those who refuse to wait for catastrophe before acting in self-defence.
Britain must now decide whether it wishes to be a meaningful participant in global security or merely a nervous onlooker, tutting from the sidelines. We should immediately grant the United States unrestricted use of British bases, free from mealy-mouthed conditions or “legal” asterisks. Furthermore, we must be prepared to deploy our own armed forces to the region. To defend our allies and secure the Straits of Hormuz is not an act of “lawlessness” – it is the highest expression of justice in a world that remains, alas, red in tooth and claw.
