Britain’s decision to finally permit the United States to use its bases for strikes against Iranian missile sites in the Strait of Hormuz is, without question, the right one. It is also, by any reasonable measure, far too late.

After weeks of escalating attacks on international shipping and a rapidly deteriorating security environment in one of the world’s most critical energy corridors, London has at last aligned itself with its closest ally. The approval allows American forces to operate from key British facilities, including RAF Fairford and Diego Garcia, to target Iranian missile capabilities threatening maritime traffic.

This is not a marginal development. The Strait of Hormuz is the chokepoint through which roughly a fifth of global oil flows. Its closure—or even sustained disruption—has immediate and profound consequences for global markets, inflation, and energy security. Iran’s actions in targeting ships have therefore not just been provocative, but economically destabilising on a global scale.

And yet, for all the clarity of the threat, the UK government hesitated.

Prime Minister Keir Starmer initially resisted Washington’s request, citing legal concerns and a desire to avoid escalation. That caution may have been defensible in the earliest days of the crisis. But as Iranian strikes intensified and allies came under direct threat, the continued equivocation began to look less like prudence and more like paralysis.

Indeed, the eventual decision came only after Iran expanded its attacks and regional tensions surged further. In other words, Britain acted not at the moment of strategic necessity, but at the point where inaction had become untenable.

This pattern—delay, drift, then reluctant alignment—is becoming a hallmark of Starmer’s premiership. It is governance by hesitation. A kind of managerial caution that too often confuses delay with deliberation.

Even America noticed.

President Donald Trump, never one to mince his words, publicly criticised the UK’s “very late response,” underscoring frustration within the alliance. While his tone may have been characteristically blunt, the underlying point resonated: in moments of geopolitical urgency, timing matters. Leadership is not just about making the right call—it is about making it when it counts.

To be clear, the UK has not been entirely absent. British bases have been involved in defensive operations earlier in the conflict, and the government has consistently called for de-escalation. But there is a difference between being present and being decisive.

And decisiveness is precisely what has been lacking.

The consequences are not merely reputational. Iran has already responded with direct threats, and even attempted missile strikes against the joint US-UK base at Diego Garcia. The message from Tehran is unambiguous: British involvement carries risks. But those risks were always present. Delaying action did not eliminate them—it merely postponed the moment of reckoning.

Meanwhile, public opinion in the UK remains sceptical, with a majority reportedly opposing involvement in US-led military action. That reality makes leadership more difficult—but also more necessary. Governments are not elected simply to follow opinion polls, particularly in matters of national security and international stability.

There is, however, a broader strategic upside to this long-delayed decision.

By ultimately backing the United States, Britain reaffirms the central pillar of its foreign policy: the transatlantic alliance. At a time when other European powers have been more hesitant or ambiguous, London’s alignment sends a signal of reliability—albeit one that would have carried far greater weight had it come sooner.

Moreover, the decision underscores a recognition that the rules-based international order—so often invoked in diplomatic rhetoric—requires enforcement. Allowing Iran to target shipping in a vital global artery without meaningful response would have set a dangerous precedent.

In that sense, the move is not just justified; it is necessary.

But necessity does not excuse delay.

The broader concern is that this episode reflects a deeper issue within the current government: an instinct to defer, to consult endlessly, to seek the least politically risky path—even when circumstances demand clarity and speed.

It is, in short, the posture of a lame-duck administration. Not in the technical sense of being at the end of its term, but in the behavioural sense: cautious to a fault, reactive rather than proactive, and increasingly defined by its reluctance to lead.

Starmer’s defenders – or apologists – will argue that careful decision-making is preferable to rash action. And they are right—up to a point. But there is a fine line between caution and inertia. In the fast-moving arena of global security, that line can determine whether a country shapes events or is shaped by them.

Britain, in this instance, has chosen—eventually—to shape events. That should be welcomed, but it should also serve as a warning. It will also be the case that future adversaries will factor London’s inertia into their own planning.

The next crisis will not wait for internal deliberations to conclude. It will not pause for political calculations or legal niceties. And if the government responds with the same hesitant rhythm—first resisting, then reconsidering, and finally conceding—it risks not just criticism, but irrelevance.

For now, the UK has eventually done the right thing. The question is why it took so long—and whether, next time, it will be any faster.
