Britain scrambles to shield Gulf allies as Iran war pounds on

POLITICO - Monday, March 16, 2026

LONDON — U.K. Prime Minister Keir Starmer has stressed since the start of the U.S. and Israeli-led war in Iran that Britain will only contribute to defensive operations, including limiting the U.S. use of British airbases, saying: “We have learned the lessons of Iraq.”

The problem as the war continues into its third week is that Starmer is now getting low marks from key allies in the Gulf for how he’s applied those lessons, according to senior military figures and diplomats who spoke to POLITICO. That has left London scrambling to deploy sufficient resources and show that it can provide adequate defensive support in the region as well as protect British assets, including its sovereign bases in Cyprus. 

Three people familiar with operational and planning strategies, granted anonymity to speak frankly about sensitive matters, said the U.K. had bungled defensive decision-making and failed to send the necessary resources to the area at the time of the first U.S. and Israeli strikes on Iran.  

Chief of the Defense Staff Richard Knighton has taken flak over delays in deploying HMS Dragon, a guided missile destroyer, to the Mediterranean for more than a week after the war started. But one former military commander familiar with conversations in government about the U.K. response said the greater fault lay in a risk-averse stance from Starmer as well as his National Security Adviser Jonathan Powell and Defense Secretary John Healey, whose fears over a domestic backlash to being embroiled in a conflict in the Middle East hobbled the U.K.’s thinking about how to support allies in the Gulf.

“No. 10 was determined to downplay any risk or perception of us getting involved and now the government is playing catch-up,” the former commander said. “And that means we are showing up late.”

Others POLITICO spoke with said the failure to deploy maritime assets — especially in minesweeper expertise and air defense — has shaken states ranging from Bahrain and the United Arab Emirates with longstanding close defense ties to the U.K.

This perceived lapse has left Britain on the back foot both in its deployment of assets and in diplomatic relations with partners, visible in the U.K.’s concerted effort last week to demonstrate support for Gulf countries facing retaliatory strikes from Iran, as Foreign Secretary Yvette Cooper travelled to Saudi Arabia.

The prime minister and defense secretary have highlighted extra resources deployed to the region since widespread unrest erupted in Iran at the start of the year, including fighter jets, air defense missiles and radar systems. 

The prime minister and defense secretary have highlighted extra resources deployed to the region since widespread unrest erupted in Iran at the start of the year, including fighter jets, air defense missiles and radar systems. And there are mounting signs that Starmer and Healey have understood the extent of sore feelings among allies and are seeking to assuage any tensions with Gulf allies as well as with the U.S. 

In a social post on Sunday, the Ministry of Defense highlighted U.K. Typhoon and F-35 jets flying over Bahrain for the first time in “defense of British interests” and Britain’s role in air protection over the United Arab Emirates, Qatar and Cyprus. Christian Turner, Britain’s ambassador to Washington, also issued a video over the weekend noting that British pilots have spent “over 300 hours in the skies above the Middle East shooting down Iranian drones and missiles” as well as drawing attention to the U.S. use of U.K. bases and sharing of intelligence. 

“We acted early to protect British people and British interests and to support our allies across the region,” a Ministry of Defense spokesperson said, specifically noting defense patrols with extra Typhoons in Qatar to support that country as well as Bahrain and the UAE. “Those preparations made a real difference, enabling our troops to conduct defensive operations from Day One.”

A Downing Street spokesperson declined to comment further, referring inquiries to the Ministry of Defense.  But a government official, granted anonymity as they were not authorized to speak on the record, insisted Starmer and Healey had “followed all military recommendations presented to them throughout the build-up” and hit out at “armchair generals who aren’t seeing the intelligence and information that our military see every day.”

Yet a person with knowledge of deployment decisions said that close allies of the U.K. were “deeply disappointed” by the lack of preparation. “There had been knowledge of the preparations for U.S. action on Iran on a large scale from around Christmas and the U.K. had visibility on that,” this person said. “But the response was wholly inadequate.”

If a full array of options had been considered, according to this person, a submarine presence from the Royal Navy might have been sent to the region as a deterrent under the terms of Operation Kipion, a long-standing umbrella for British security, intelligence gathering and deterrence to the Gulf.

One area of concern has been the decommissioning of ships, some of which were moved for servicing and routine upgrades in recent weeks. 

HMS Middleton, which was based in Bahrain, ​arrived back in Britain on March 1 — the day after the U.S. and Israel opened their attack — for maintenance and a technological upgrade. The vessel, ⁠which is more than 40 years old, was ​no longer certified to sail, according to the MOD. The U.K.’s only mine-hunting ship was brought back to Britain to save money just as strikes began, according to The Times

Healey told reporters this week he was still considering “additional options” for protecting the Strait of Hormuz. 

The former commander was frustrated by a gap between the prime minister and Healey’s robust language about Britain’s need for war-readiness and the reality of its actions. 

“We have the prime minister and defense secretary talking about ‘preparing the nation for war’ on a running basis, which is ironic, as we and our allies ended up not deploying deterrent force and taking a week to deploy a major warship to defend Cyprus in good time to show our strong  defensive intentions,” this person said.

A senior Gulf diplomat said the U.K.’s early response to the conflict fell short of what Gulf partners expected given Britain’s longstanding military ties in the region. There were “a lot of phone calls,” the diplomat said, but not much in the way of “serious support.”

John Foreman, a former deputy head of the Combined Maritime Forces in Bahrain, said Starmer’s cautious approach was bound to cause continued problems as the conflict continues, particularly amid rising focus on protecting the Strait of Hormuz.

“Wiser, less cautious heads would have got ahead of the game,” Foreman said. “It comes from Starmer ultimately and the tone of his government. It’s too late for Powell to be asking for options on the eve of war — and for Healey to still be pondering options now.”
