Let us dispense with the niceties. The Joint Comprehensive Plan of Action, that masterwork of diplomatic sophistry, is gasping its last breath, and the British establishment is wringing its hands as if a cherished maiden aunt had taken ill. But this is no sentimental matter. This is about oil. This is about the Royal Navy. This is about the slow, grinding decline of a once-great maritime power that has forgotten how to think strategically.
First, the oil. Iran sits on the world’s fourth-largest proven oil reserves and the second-largest gas reserves. The JCPOA, for all its flaws, at least allowed a trickle of Iranian crude onto global markets, which kept prices within the tolerable bounds of Her Majesty’s Treasury. Without the deal, Iran’s exports collapse, prices spike, and the already strained British motorist—subsidising the green fantasies of a government that cannot build a wind turbine without a German engineer—feels the pinch. Meanwhile, Russian and Saudi rivals chuckle into their beards. Britain, once the world’s foremost oil trader, now watches from the sidelines, a spectator in a game it invented.
Second, the navy. The Royal Navy, that glorious shadow of its former self, still has a job to do in the Gulf: ensure the free flow of oil, protect British tankers, and show the flag. Without the JCPOA, Iran returns to its old tricks—harassing shipping, mining the Strait of Hormuz, and testing the resolve of a British government that cannot decide if it wants a navy or a floating carbon-neutral exhibit. The Hunt-class minehunters, the Type 23 frigates, the dwindling number of hulls: these are the instruments of a nation that once ruled the waves but now can barely police a bathtub. If the Iran deal collapses, expect the Strait to become a shooting gallery, and expect the Royal Navy to be humiliated by speedboats and drones.
But the deeper rot is intellectual. The JCPOA was never about peace; it was about postponing a decision. The West hoped that integrating Iran into the global economy would soften its theocratic edges, a notion as naive as believing a Victorian opium den could be reformed by installing a potted fern. Iran’s regime does not want integration; it wants regional hegemony, nuclear latency, and the ability to threaten Israel at will. The Europeans, led by a Britain that has lost the will to wield power, pretended that sanctions relief and diplomatic chatter would transform a revolutionary state into a normal one. It did not work. It never works.
Consider the historical parallels. The 1930s saw a similar fantasy: that appeasing Hitler would satisfy his ambitions. It did not. Today’s appeasement of Iran is not about selling out Czechoslovakia but about selling out the rules-based order itself. Every concession to Tehran is a signal to Pyongyang, to Moscow, to any aspiring tyrant that the West will trade principles for a quiet life. And Britain, once the arch-exporter of liberal order, now imports chaos.
What is to be done? First, accept that the JCPOA is dead. Second, rebuild the Royal Navy to a size and capability that can project power without begging for American or French escorts. Third, develop a genuine energy policy that does not rely on the goodwill of ayatollahs or the whim of wind. Fourth, and most importantly, recover the spine that made Britain great: a willingness to defend interests, not just ideals, with force if necessary.
Yes, this will cost money. Yes, it will offend the bien-pensant opinion of the chattering classes. But empires are not sustained by think-pieces and carbon targets. They are sustained by coal, by steel, by ships, and by the quiet certainty that when Britain speaks, it means what it says. The Iran deal is unravelling. The question is whether Britain will unravel with it.
