A rumor spread in March 2026 that U.K. Prime Minister Keir Starmer said on X that the U.S. forces would have to withdraw from U.K. air bases if the administration of U.S. President Donald Trump decided to end the country's commitment to NATO. 

The claim emerged after Trump said NATO allies would face a "very bad future" over their unwillingness to help secure the Strait of Hormuz, which Iran has controlled since the U.S. and Israel began to attack it on Feb. 28, 2026.

One X user shared a screenshot of the supposed post, calling the alleged decision an "escalation" (archived):

Starmer's alleged post read, in part:

So if President Trump intends to end America's commitment to NATO, I would expect the rapid withdrawal of US forces from British bases within 48 hours, in an orderly fashion, agreed with the Ministry of Defence & our local communities.

And since the United States has benefited from decades of access to RAF Lakenheath, Mildenhall & ten other facilities on British soil without paying a penny in ground rent, my government would also expect a full and final settlement of historic rent by the end of the week, on commercial terms.

That is what sovereignty looks like. You do not get to lecture Europe about "burden sharing" while flying your aircraft from our countryside rent-free.

Britain will always value the Atlantic alliance. But we will not be taken for granted by any president of the United States – past, present or future.

Several Snopes readers searched the site and emailed seeking to verify the rumor. The screenshot appeared across social media, including on Threads and Reddit.

As we outline below, the rumor was fictional. It originated from the Threads account @political.satire, which later explicitly called the rumor a "spoof." As such, the claim is labeled satire.

To determine the rumor's origin, we first searched Starmer's X account for such a statement, to no avail. Then we used search engines such as Bing, DuckDuckGo, Google and Yahoo. If Starmer had really threatened to demand the withdrawal of U.S. forces from U.K. bases should it leave NATO, reporters from reputable news outlets, such as The Associated Press or Reuters, would have widely reported on it. That was not the case.

Threads account @political.satirical first shared the fabricated screenshot on March 18:

Starmer just dropped the nuke on Trump and America about NATO.

Holy s***balls Batman!

The account later described the supposed Starmer post as a "spoof" in a series of three posts. The first read:

So, the SKS [Sir Keir Starmer] spoof from yesterday about Trump & NATO & UK airbases…

Probably blown through over 20 million views across this platform alone… & I am being conservative.

Most people just ripped the image from my post, and posted it as their own breaking news thread.

So a LOT of people, made out like bandits, with my work. 100's of thousands of views, thousands of comments, millions of likes and hundreds of thousands of shares,

This is NOT a complaint, that is working as intended. 😈

The "interests" below the bio included "satire," "satirenews," "SatireThreads" and "comedy."

The Threads account had shared other fictitious stories based on real events or people. For example, it posted the false rumor on March 19, 2026, that Trump had died of a heart attack in the Oval Office

Snopes has debunked similar pieces of media before. For example, we alerted readers to a fake story about singer and actor Barbra Streisand having brain cancer.

Please note: Snopes is in the business of facts. We label these rumors "satire" based on their creators' description of them. It is your call whether you agree.
