Trump this week sharply criticized German Chancellor Friedrich Merz, calling him “totally ineffective” after Merz questioned the U.S. approach to the Iran conflict and said Washington lacked a clear exit strategy. On Friday, the Pentagon announced plans to withdraw 5,000 troops from Germany and confirmed higher tariffs on European Union cars and trucks, a move expected to hit Germany’s export-heavy economy particularly hard.

The administration has also turned its focus toward Britain, with Trump describing Prime Minister Keir Starmer as “not Winston Churchill” and threatening major tariffs on British imports, further widening tensions with traditional U.S. allies.European diplomats described the atmosphere as increasingly unpredictable.

“It’s unnerving to say the least,” one diplomat said, speaking on condition of anonymity. “We are braced for anything, anytime.”The friction has been aggravated by Washington’s push for stronger allied backing in the Iran war, particularly around securing the Strait of Hormuz, a vital global oil shipping route disrupted by the conflict.

Trump has accused European governments of failing to provide adequate military support for U.S. operations that he argues protect broader Western interests.Reuters reported last week that the Pentagon had internally discussed punitive options for NATO members viewed as unsupportive, including suspending Spain from NATO and reviewing U.S. recognition of British sovereignty over the Falkland Islands.

Some European officials said they were adapting to Trump’s confrontational style. One diplomat pointed to former German Chancellor Angela Merkel as a model for managing relations with Trump during his first term.“You must not react immediately, you must let the storm pass, while standing firmly on your positions,” the diplomat said, adding that attempts at personal flattery had also failed to prevent criticism.

Italian Prime Minister Giorgia Meloni, once viewed as one of Trump’s closest European political allies, also faced criticism after she publicly opposed the Iran war and condemned what she called Trump’s “unacceptable” remarks about Pope Leo.Even NATO Secretary General Mark Rutte, often seen in Europe as skilled at managing Trump, was reportedly rebuked during a recent White House meeting.

Within the Republican Party, Trump’s hardline stance has drawn some resistance. Representative Don Bacon said repeated attacks on NATO partners were damaging U.S. interests.

“The continued attacks on NATO allies are counterproductive, the comments hurt Americans,” Bacon wrote on X, noting that U.S. air bases in Germany remain strategically important for operations across Europe, Africa and the Middle East.German military officials were reportedly surprised by Trump’s announcement on troop reductions, especially after what they described as constructive Pentagon meetings earlier this week.

General Carsten Breuer, Germany’s top military officer, had indicated he received positive support for Berlin’s updated defense strategy during talks in Washington.Analysts say the political mood in Europe is shifting, with leaders becoming more willing to publicly challenge Washington as domestic pressure rises over the economic and security fallout of the Iran war, including rising energy costs and trade disruptions.

Jeffrey Rathke of the American-German Institute at Johns Hopkins University said Chancellor Merz’s sharper tone reflected a broader recalibration.“It’s pretty clear that something has changed,” Rathke said, noting that European governments increasingly believe they can no longer rely on the post-World War II security framework without significantly expanding their own military capabilities.

Al-Sharaa met Starmer at 10 Downing Street, marking the first visit by a Syrian head of state to London since former president Bashar Assad traveled to the UK in 2002.According to a Downing Street spokesperson, discussions covered migration returns, border security and efforts to combat people-smuggling networks.

Starmer also welcomed steps taken by Damascus against Daesh, citing progress in counter-terrorism cooperation between the two countries.The talks also addressed broader regional stability concerns alongside economic cooperation.

The visit comes as Syria seeks foreign investment to rebuild infrastructure damaged during years of civil war. Al-Sharaa is expected to hold further meetings with senior British officials during his stay.

He was accompanied by Foreign Affairs Minister Asaad Hassan Al-Shaibani and Economy Minister Nidal Al-Shaar.European outreach continuesAl-Sharaa arrived in London following a visit to Germany, where he met Chancellor Friedrich Merz, as part of a broader diplomatic push to re-engage European partners.

No specific agreements were announced following the London meeting.
