German president slams Trump’s Iran war as illegal

BERLIN — German President Frank-Walter Steinmeier on Tuesday condemned U.S. President Donald Trump for going to war with Iran, calling the conflict a violation of international law and warning of a transatlantic rupture comparable to Germany’s break with Russia.

Steinmeier’s role in German politics is largely ceremonial, but his sharp criticism of the war and the U.S. president is likely to put additional pressure on German Chancellor Friedrich Merz, who has stopped short of other European leaders in calling the war illegal even as he has grown increasingly critical of what he sees as the lack of an exit strategy on the part of the U.S. and Israel.

“This war violates international law,” said Steinmeier, who is a member of the center-left Social Democratic Party (SPD), which rules in a coalition with Merz’s conservatives and has been more critical of the ongoing attacks. “There is little doubt that, in any case, the justification of an imminent attack on the U.S. does not hold water,” he added.

Steinmeier, speaking in front of an audience of German diplomats in Berlin, criticized Trump for withdrawing from the nuclear deal with Iran during his first term in office. The president, who served as Germany’s foreign minister from 2013 to 2017, had helped negotiate that deal.

“This war is also — and please bear with me when I say this, as someone directly involved — a politically disastrous mistake,” said Steinmeier. “And that’s what frustrates me the most. A truly avoidable, unnecessary war, if its goal was to stop Iran from developing a nuclear weapon.”

Despite the president’s largely symbolic role, his strident criticism is likely to fuel a growing domestic debate over Germany’s stance on the Iran war and its relationship with the U.S.

Merz and his fellow conservatives were initially far more supportive of the U.S. and Israeli attacks on Iran than many other EU countries, arguing that Germany shares the goal of regime change in Tehran. But as the conflict has expanded and the economic and security effects on the EU’s biggest economy have become clearer, the chancellor has become far more openly critical, saying the war has raised “major questions” about Europe’s security.

Steinmeier, who refrained from criticizing Israel directly, also compared the transatlantic rift during Trump’s second term to Germany’s divorce from Russia in the wake of Moscow’s full-scale invasion of Ukraine in 2022.

“Just as I believe there will be no going back to the way things were before February 24, 2022 in our relationship with Russia, so I believe there will be no going back to the way things were before January 20, 2025 in transatlantic relations,” Steinmeier said, referring to the day of Trump’s second inauguration. “The rupture is too deep.”

Steinmeier then urged his country to become more independent of the U.S., both in terms of defense and technology, arguing that such autonomy is necessary to prevent Trump administration interference in his country’s domestic politics.

The German military “must become the backbone of conventional defense in Europe,” he said. “In the technological sphere, our dependence on the U.S. is even greater. This makes it all the more important that we do not simply accept this situation.”
