Trump's Criticism Intensifies Strain in US-Europe Financial and Political Ties

By Andrea Shalal

Escalating Tensions and Their Impact on Transatlantic Relations

WASHINGTON, May 1 (Reuters) - The past weeks have not been reassuring for those who thought Europe could navigate its tricky relationship with U.S. President Donald Trump.

Trump's Recent Attacks on European Leaders

Trump this week lashed out at German Chancellor Friedrich Merz over his criticism of the Iran war, calling him "totally ineffective," and threatened to cut the 36,400 U.S. troops based in Germany. 

He has taken aim at British Prime Minister Keir Starmer in strikingly personal terms, saying that he is "not Winston Churchill," and threatening to impose a "big tariff" on imports from the UK. 

More worrying for Europe, Trump's Defense Department has floated punishing NATO allies that it believes are not supporting U.S. operations in the war with Iran, including suspending Spain as a member and reviewing U.S. recognition of the Falkland Islands as a UK possession. 

"It's unnerving to say the least," said one European diplomat. "We are braced for anything, anytime."

Diplomatic Responses and Strategies

The latest U.S. broadsides, fired over disagreements about the Iran war, have seemingly turned U.S.-Europe relations back to the early days of the second Trump administration and raise fresh questions about the best way to handle a mercurial ally. 

A second European diplomat said former German Chancellor Angela Merkel, who had a rocky relationship with Trump during his first term, had modeled the right approach.

“We’ve all learned a bit how to handle Trump by now. You must not react immediately, you must let the storm pass, while standing firmly on your positions," the diplomat said. 

Even those who attempted flattery have faced Trump's ire, the diplomat said. "All those who tried that got their volley of insults, like the others. So everybody realizes now that flattery doesn’t work either," the diplomat said. 

The White House had no immediate comment.

Back in the Crosshairs: Renewed Pressure on Europe

BACK IN THE CROSSHAIRS

Last year, U.S. tariffs, Trump's push to acquire Greenland and a cut in U.S. aid to Ukraine deeply unsettled transatlantic relations. 

Some leaders, including Starmer, Merz and Italian Prime Minister Giorgia Meloni, worked to stabilize ties through regular visits, trade deals and policy shifts, including some that have been unpopular domestically, only to find themselves in the crosshairs again following the start of the Iran war in February.

Trump's Criticism of NATO and European Leaders

Even NATO Secretary General Mark Rutte, known in Europe as a "Trump whisperer", faced a scolding from Trump during a White House meeting this month. Trump also blasted Meloni - once his favorite European leader - after she criticized the Iran war and chided Trump for what she called an "unacceptable" verbal assault against Pope Leo.

Internal US Political Dissent

While many members of the U.S. administration are deeply skeptical of Europe, not all members of the president's Republican Party support Trump's approach. 

"The continued attacks on NATO allies are counterproductive, the comments hurt Americans," wrote Republican Representative Don Bacon on X on Thursday, following Trump's threat to cut troop levels in Germany. 

"The two big airfields in Germany give us great access in three continents. We are shooting ourselves in our own feet."

European Officials React to US Policy Shifts

Some of Trump's social media posts this week caught European officials off guard. 

Less than two hours before the post about U.S. troop levels in Germany, Berlin's top general, Carsten Breuer, told reporters that he got a thumbs up for Germany's new military strategy when he met with Defense Undersecretary Elbridge Colby at the Pentagon earlier in the day. He gave no indication that any troop reductions were discussed.

The German embassy declined to comment.

German military officials were fairly sanguine about the situation and military cooperation remained intact, a former senior U.S. defense official said. "They're saying, 'We've seen this movie before. This is going to be a lot of bluster and at the end of the day, nothing is going to change.'"

Bolder European Opposition to US Policies

BOLDER OPPOSITION TO THE U.S.

Growing Criticism and Domestic Pressures

Jeffrey Rathke, a former U.S. diplomat who heads the American-German Institute at Johns Hopkins University, said European allies were becoming bolder in their opposition to Trump's policies, not least due to political pressure at home.

"Merz has become increasingly pointed in his criticisms of the U.S. decision to go to war against Iran," he said. "It's pretty clear that something has changed for someone who, just two months ago, went out of his way to say, 'It is not our time to lecture the United States.'"

"The U.S. war is not just something that the German public can observe in a detached way. It's something that affects them," he added, citing a war-related surge in energy costs.

Shifting Transatlantic Dynamics and Future Outlook

European diplomats say they remain committed to transatlantic ties even as the "tectonic plates" of Europe and the United States are shifting, but changes are required. 

"For us, the main lesson is that we can't rely anymore on the post World War status quo, and that we need to be not only a soft power space, but a space that can be also backed by power," said one Western diplomat, noting that Europeans were acting quickly to expand their military capabilities.
