Diplomatic "safety" is the participation trophy of international relations. When former diplomats like Fabian lament that the UK cannot respond to Iran’s demands for security guarantees, they aren't describing a failure of policy. They are describing a failure of imagination. The narrative usually goes like this: Iran wants assurances that Western powers won't freeze their assets or topple their regime, and the UK, bound by the "rules-based order" and its alliance with Washington, simply has its hands tied.
It is a comfortable lie. It allows bureaucrats to shrug their shoulders while the geopolitical clock ticks toward a standoff that nobody is actually prepared to handle. The reality is far more jagged. The UK doesn't lack the ability to provide safety; it lacks the incentive to admit that "safety" in the 21st century is a tradable commodity, not a legal status.
The Sovereign Debt Trap
The lazy consensus suggests that international law governs these interactions. It doesn't. Leverage does. When Iran asks for safety, they aren't asking for a signed letter from the Foreign Office promising to be nice. They are asking for a hedge against the weaponization of the global financial system.
The UK’s refusal to engage with this isn't about "safety" in the physical sense. It’s about the fact that London is the clearinghouse for the very mechanisms used to strangulate the Iranian economy. To grant Iran "safety" would be to de-weaponize the British pound and the London insurance markets.
I have watched policy desks dance around this for a decade. They treat sanctions as a moral dial you can turn up or down. They aren't. They are an architectural choice. By claiming the UK "cannot respond," diplomats are actually saying they refuse to relinquish the one piece of structural power they have left: the ability to make an adversary's money disappear overnight.
The Myth of the "Inability to Guarantee"
Fabian and his cohort argue that because the UK cannot control the US Treasury’s Office of Foreign Assets Control (OFAC), any guarantee London gives is worthless. This is a classic deflection.
If the UK wanted to provide a credible safety net, it would utilize sovereign wealth maneuvers or state-backed insurance vehicles that bypass the standard transatlantic banking rails. We saw the skeleton of this with INSTEX (the Instrument in Support of Trade Exchanges). It failed not because it was technically impossible, but because the European powers lacked the stomach to actually use it. They wanted the optics of diplomacy without the risk of a fallout with the US.
In any high-stakes negotiation, if you say "I can't do that," you are usually saying "I am afraid of the person standing behind me." For a country that prides itself on "Global Britain," admitting such total subservience to US financial policy is a confession of irrelevance.
Why "Safety" is the Wrong Metric
The premise of the question is flawed. We shouldn't be asking how to give Iran safety. We should be asking why we are still using a 19th-century diplomatic toolkit to solve a 21st-century resource and energy crisis.
Safety is not a static condition. It is a derivative of mutual pain.
- Economic Interdependence: True safety comes when the cost of attacking you is higher than the benefit. The UK has spent twenty years ensuring it has zero economic skin in the Iranian game.
- Asymmetric Risk: By keeping Iran "unsafe," the UK invites asymmetric responses—cyber warfare, maritime harassment in the Strait of Hormuz, and proxy conflicts.
- The Nuclear Shadow: Every time a Western diplomat says "we can't guarantee your security," they are effectively writing the marketing copy for Iran’s nuclear program.
If you tell a regime they will never be safe within the current global architecture, you are giving them a binary choice: collapse or build a bigger stick. We are currently choosing the latter for them.
The Institutional Cowardice of "Rules-Based" Rhetoric
The term "rules-based order" is the ultimate shield for the uninspired. It is used to justify inaction by pretending that the rules are handed down on stone tablets. In reality, the rules are rewritten every time a major power decides they are no longer convenient.
When the US pulled out of the JCPOA (the Iran nuclear deal), the "rules" were shattered. The UK’s insistence on following the remaining fragments while refusing to offer Iran a workaround is not "principled." It is a managed decline of influence.
I’ve sat in rooms where "legal feasibility" was used to kill every creative solution to the debt Iran is owed from the 1970s tank deal. It took decades to settle a basic commercial debt because of "safety" concerns. That isn't diplomacy; it's debt collection with a flag on the desk.
The Cost of the Status Quo
What the "lazy consensus" ignores is the opportunity cost. While the UK remains paralyzed by its inability to offer safety, other players are stepping in with their own versions of it. China’s 25-year strategic pact with Iran isn't based on "safety" in the Western sense. It's based on an exchange of energy for infrastructure—a hard-asset guarantee that the UK is now structurally unable to match.
The downside of my contrarian view is obvious: providing these guarantees would spark a massive diplomatic row with Washington. It would put the City of London in the crosshairs of US secondary sanctions. But at least that would be a choice. The current path is a slow-motion car crash where we pretend our hands aren't on the wheel.
Stop Asking the Wrong Questions
People ask: "How can the UK bridge the gap between Iran and the West?"
The honest, brutal answer: It can’t, as long as it prioritizes its role as a US satellite over its role as a sovereign mediator.
People ask: "Is Iran’s demand for safety reasonable?"
Reasonable is irrelevant. It is logical. No rational actor hands over their primary leverage (nuclear development) without a guarantee that they won't be liquidated the following year.
If you want to move the needle, stop talking about "safety" as a legal concept. Start talking about it as an escrow. The UK could facilitate a multilateral trust, backed by commodities, that sits outside the reach of a single nation’s executive orders. This would require backbone. It would require the UK to actually act like a mid-sized power with its own interests.
Instead, we get op-eds from ex-diplomats telling us why things are impossible. They aren't impossible. They are just uncomfortable.
The UK is perfectly capable of responding to demands for safety. It simply prefers the safety of its own cages. If the goal is to prevent a nuclear-armed Iran and a destabilized Middle East, the current "inability to respond" is the most dangerous posture we could take.
The choice isn't between safety and risk. It's between a controlled risk today and a catastrophic one tomorrow. Pick one.
