The United States is withdrawing 5,000 troops stationed in NATO ally Germany, the Pentagon announced on Friday, as a rift over the Iran war widens between President Donald Trump and Europe.

Trump had threatened a drawdown in forces earlier this week after sparring with German Chancellor Friedrich Merz, who said Monday that Iran was humiliating the U.S. in talks to end the two-month-old war and that he did not see what exit strategy Washington was pursuing.

A senior Pentagon official, speaking on condition of anonymity, said recent German rhetoric had been “inappropriate and unhelpful.”

“The president is rightly reacting to these counterproductive remarks,” the official said.

The Pentagon said the withdrawal was expected to be completed over the next six to 12 months. Germany is home to around 35,000 active-duty U.S. military personnel, more than anywhere else in Europe.

The official said the drawdown would bring U.S. troop levels in Europe back to roughly pre-2022 levels, before Russia’s invasion of Ukraine triggered a buildup under then-president Joe Biden.

The official also cast the decision as part of the Trump administration’s push for Europe to become the continent’s main security provider. Still, it is another potent reminder of Trump’s willingness to respond to what he sees as disloyalty from allies.

Reuters exclusively reported last week that an internal Pentagon email outlined options to punish NATO allies that Washington believes failed to ​support U.S. operations in the war with Iran, including suspending Spain from NATO and reviewing the U.S. position on Britain’s claim to the Falkland Islands.

Ties with European nations fray

It is unclear if more withdrawals from Europe will follow. On Thursday, Trump said “probably” when asked whether he would consider pulling U.S. troops out of ​Italy and Spain.

Last month, he threatened to impose a full U.S. trade embargo ​on Spain, where the socialist leadership said it would not allow its bases or airspace to be used to attack Iran. The U.S. has two important military bases in Spain: Naval Station Rota ‌and Morón Air ⁠Base.

Trump has also clashed with Italian Prime Minister Giorgia Meloni over the Iran war and Trump’s criticism of Pope Leo. The U.S. president said in April that Meloni, once a strong Trump supporter, lacked courage and had let Washington down.

Trump has chastised NATO allies, too, for not sending their navies to help open the Strait of Hormuz. The waterway, a chokepoint for global oil shipments, has remained virtually shut during the Iran conflict, causing market turmoil and unprecedented disruption in energy supplies.

Merz has said Germans and Europeans were not consulted before the U.S. and Israel began attacking Iran on Feb. 28, and that he had conveyed his skepticism about the conflict directly to Trump afterwards.

“The president has been very clear about his frustrations about our allies’ rhetoric and failure to provide support for U.S. operations that benefit them,” the senior Pentagon official said.

Trump has long wanted to reduce the U.S. troop presence in Germany. He pushed for a reduction at the end of his first term, but that cut was never enacted. Trump lost the election, and Biden reversed the plan.

Trump’s Wednesday announcement that he was reviewing U.S. troop levels in Germany surprised German military officials who spoke to Reuters, citing what they described as constructive meetings at the Pentagon earlier in the day.

They argue that Germany has done more than other allies to support the U.S. war in Iran, including allowing the use of bases and giving permission for overflights. Germany is also home to a huge military hospital in Landstuhl.

Earlier this week, the German government approved key targets for its 2027 budget, including a strong commitment to ⁠increase defence spending.

Imran Bayoumi, a former Pentagon official, said that while the cuts in Germany were not as drastic as they might have been, they nonetheless risked further dividing the U.S. and Europe.

“European leaders will likely push more to bolster their defence spending, viewing Washington as increasingly unreliable and untrustworthy,” said Bayoumi, now with the Atlantic Council.

As part of Trump’s withdrawal decision, a brigade combat team now in Germany will be pulled out of the country, and a long-range fires battalion that the Biden administration had planned to begin deploying to Germany later this year will no longer be sent, the official said.
