Trump threatens to reduce troop numbers in Germany amid growing row with Nato allies

The US may reduce its number of troops deployed in Germany, Donald Trump has announced, days after the country’s chancellor said America was being “humiliated” by Iran.

In a post on his Truth Social platform, the US president said his administration was “studying and reviewing the possible reduction of troops in Germany, with a determination to be made over the next short period of time”.

On Monday, Friedrich Merz suggested the Trump team was being outplayed in its negotiations with Iran to secure an end to the ongoing war and a reopening of the strait of Hormuz.

“The Iranians are obviously very skilled at negotiating, or rather, very skilful at not negotiating, letting the Americans travel to Islamabad and then leave again without any result,” the German chancellor said.

Merz reiterated his criticisms on Wednesday, saying Europe was “suffering” from the consequences of the closure of the Hormuz strait.

Trump cancelled a second trip by US negotiators to Islamabad last week. Since then, discussions over Iran’s nuclear programme, missiles and sanctions relief have hit an impasse.

Trump on Tuesday accused Merz of thinking it’s “OK for Iran to have a nuclear weapon” and said the chancellor “doesn’t know what he’s talking about!”

Earlier on Wednesday Merz brushed off those comments, saying his relationship with Trump remains “as good as ever”, but the president’s threat to withdrawal US troops is likely to cause concern in Berlin and across Europe, coming amid a period of heightened tensions between the US and its traditional allies in Europe that has seen the president step up his threats to withdraw from the Nato alliance.

On 1 April the Trump said he was “absolutely without question” considering withdrawing from Nato because of the European allies failure to take part in the US-Israeli war on Iran and help secure the economically vital strait of Hormuz.

Such a move from the US administration would be catastrophic for the security of Europe, but is seen as unlikely because of US legislation passed in 2024 that prevents a president from withdrawing from Nato without a two-thirds Senate majority or an act of Congress.
