Donald Trump just threw another wrench into the transatlantic alliance. Less than a week before the upcoming NATO summit in Ankara, Turkey, the US President took to Truth Social to blast European allies, explicitly singling out the UK and France with a familiar grievance: "They were not there for us!!!"
He called the current state of US support for NATO "ridiculous" and a "one-sided path," backing up his tirade with charts comparing massive US defense outlays to the much smaller budgets of London and Paris.
This isn't just standard campaign trail rhetoric anymore. It's the fallout of a bitter, real-world diplomatic fracture. The immediate catalyst for Trump's latest outburst is the refusal of major European allies to back the recent US military operations in Iran. While Washington expected its closest partners to fall in line, countries like the UK pushed back against demands to help police the Strait of Hormuz, and others actively blocked US aircraft from using their airspace or bases. For Trump, that was the ultimate test of the alliance. And in his view, Europe failed.
The Real Numbers Behind the NATO Spending Row
To understand why Trump keeps taking swings at the UK, you have to look at how his administration views military math.
Trump has long complained that Europe treats the US like an insurance policy it doesn't want to pay for. Last year, under intense pressure from the White House, NATO leaders agreed to a massive new target: boosting defense spending to 5% of GDP by 2035. For context, the old target was just 2%.
Country Estimated Current Defense Spending (% of GDP)
United States ~3.5% - 4%
United Kingdom ~2.3%
France ~2.1%
Even though NATO Secretary General Mark Rutte recently tried to smooth things over by showing Trump data that European defense hikes have created 195,000 American jobs through military investments, Trump isn't buying the charm offensive. The administration's focus remains fixed on the fact that when the US went to war, Europe stayed home.
Rewriting History and the Afghanistan Insult
The fracture between Trump and Downing Street isn't just about current budgets; it's deeply personal and historical. Earlier this year, Trump sparked absolute fury across the British political spectrum during a Fox News interview. He suggested that during the war in Afghanistan, NATO troops—including British forces—"stayed a little back, a little off the front lines".
That comment went down like a lead balloon in London. The UK lost 457 service members in Afghanistan. Prime Minister Keir Starmer called the remarks "insulting and frankly, appalling," while conservative opposition leaders blasted it as "complete nonsense". Even die-hard British Trump allies like Nigel Farage had to publicly break ranks and admit the president was flat-out wrong.
The irony here is massive. Afghanistan is the only time in history that NATO's Article 5 collective defense clause was ever invoked. Europe went to war because America was attacked on 9/11. For Trump to rewrite that history to claim Europe has never been there for the US shows just how broken the trust has become.
Chagos, Greenland, and the New Geopolitics
The friction is already leaking into critical strategic territory. Look at what's happening with Diego Garcia, the vital US military base in the Indian Ocean. The UK had been planning to hand over ownership of the surrounding Chagos Islands to Mauritius. But following Trump’s public insults and his bizarre threats earlier this year to forcibly seize Greenland from Denmark, London quietly paused the deal. British officials are terrified of showing any sign of "weakness" that might provoke a unpredictable White House.
So, what happens next? The Wall Street Journal reported that Trump is actively reviewing plans to punish unhelpful allies by pulling US troops out of countries that didn't support the Iran operations and moving them to nations that did. With 84,000 US troops stationed across Europe, a sudden reshuffle would throw continental security into chaos.
If you are a business leader or a policy analyst tracking international risk, the Ankara summit is no longer a routine diplomatic photo-op. It's a damage control mission. Keep a close eye on the troop movement proposals and whether the UK tries to mend fences by fast-tracking its defense budget toward that brutal 5% target. The Special Relationship isn't dead, but it's running on fumes, and Washington is no longer pretending otherwise.
