US President Donald Trump has threatened to review America's position on Britain's claim to the Falkland Islands, according to a confidential Pentagon email outlining potential punitive measures against NATO allies deemed insufficiently supportive of US operations in the war with Iran.
The internal memo, obtained by Reuters, details a range of options under consideration, including the suspension of Spain from the alliance and a reassessment of US diplomatic backing for longstanding European overseas territories such as the Falklands. The document reflects significant frustration within the Pentagon over certain allies' perceived reluctance to grant Access, Basing, and Overflight (ABO) rights essential for the conflict.
Pentagon frustrations and proposed measures
An official familiar with the email, speaking on condition of anonymity, described ABO as “just the absolute baseline for NATO” and confirmed that the options are circulating at high levels within the Pentagon. The proposals also envision suspending “difficult” countries from prominent positions within the NATO framework.
However, the official stressed that the email does not suggest the United States would actually implement these measures, nor does it propose closing US bases in Europe. The official declined to comment on whether the options include a widely anticipated drawdown of US forces from the continent.
Pentagon Press Secretary Kingsley Wilson responded to inquiries by stating: “As President Trump has said, despite everything that the United States has done for our NATO allies, they were not there for us. The War Department will ensure that the President has credible options to ensure that our allies are no longer a paper tiger and instead do their part.” Wilson declined further comment on internal deliberations.
Background: The Iran war and NATO tensions
The US-Israeli war with Iran, which began with an air campaign on 28 February, has raised serious questions about the future of the 76-year-old alliance. Trump has repeatedly criticised NATO allies for failing to deploy naval forces to help secure the Strait of Hormuz, which became inaccessible to global shipping following the onset of hostilities.
In a 1 April interview with Reuters, Trump openly considered withdrawing from NATO, asking: “Wouldn't you if you were me?” He has also insulted UK Prime Minister Keir Starmer, calling him cowardly for refusing to join the war, labelling him “No Winston Churchill” and describing Britain’s aircraft carriers as “toys.”
UK and European positions
Britain, France, and other European nations have argued that joining the US naval blockade would effectively mean entering the war, but have expressed willingness to help keep the Strait open once a lasting ceasefire is achieved or the conflict ends. The UK initially denied a US request to allow aircraft to attack Iran from two British bases but later agreed to permit defensive missions aimed at protecting regional residents, including British citizens, amid Iranian retaliation.
Spain’s Socialist government has stated it will not allow its bases or airspace to be used for attacks on Iran. The United States maintains two major military bases in Spain: Naval Station Rota and Morón Air Base. The Pentagon email argues that suspending Spain from NATO would have limited operational impact but significant symbolic weight.
Spanish Prime Minister Sanchez, when asked about the report ahead of an EU leaders’ meeting in Cyprus, said: “We do not work off emails. We work off official documents and government positions, in this case of the United States.”
Falkland Islands: A sensitive issue
The memo includes an option to reconsider US diplomatic support for European “imperial possessions,” specifically citing the Falkland Islands near Argentina. The US State Department currently states that the islands are administered by the United Kingdom but are claimed by Argentina, whose President Javier Milei is a Trump ally. Britain and Argentina fought a brief war in 1982 over the islands, resulting in 650 Argentine and 255 British deaths before Argentina’s surrender.
Defense Secretary Pete Hegseth recently told reporters at the Pentagon that “a lot has been laid bare” by the Iran war, noting that Iran’s longer-range missiles cannot reach the United States but can strike Europe. “We get questions, or roadblocks, or hesitations … You don’t have much of an alliance if you have countries that are not willing to stand with you when you need them,” Hegseth said.
