The US Department of Defence plans to withdraw 5,000 troops from Germany, amid a spat between US President Donald Trump and German Chancellor Friedrich Merz over the war with Iran.

The decision comes a day after Trump criticised Merz, who suggested the US had been “humiliated” by Iranian negotiators.

In social media posts on Thursday, Trump said Merz was “doing a terrible job” and had “problems of all kinds”, including on immigration and energy. Trump has also suggested pulling US troops from Italy and Spain.

The US has a significant military presence in Germany, with more than 36,000 active duty troops assigned to bases across the country as of last December.
