Recent weeks have raised fresh concerns across Europe over its relationship with US President Donald Trump. Statements and policy signals from Washington have added strain, particularly around disagreements linked to the Iran war.
European officials now face renewed uncertainty about how to manage ties with a key ally.
The criticism extended to British Prime Minister Keir Starmer. Trump described him in personal terms, stating he is "not Winston Churchill," and raised the possibility of imposing a "big tariff" on goods imported from the United Kingdom.
Trumps Europe attacks deepen transatlantic strain At the same time, the US Defense Department has discussed measures against NATO allies it believes are not backing US operations in Iran. These include the possibility of suspending Spain's NATO membership and reconsidering US recognition of the Falkland Islands as a British territory.
A European diplomat described the situation as "unnerving to say the least," adding, "We are braced for anything, anytime."
Another European diplomat pointed to the approach taken by former German Chancellor Angela Merkel during Trump's first presidency. The diplomat said, "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."
Escalating criticism and policy threats
Donald Trump has publicly criticised several European leaders in recent days. He targeted German Chancellor Friedrich Merz, calling him "totally ineffective" following Merz's remarks on the Iran war. Trump also warned that the United States could reduce its 36,400 troops stationed in Germany.The criticism extended to British Prime Minister Keir Starmer.

Iran war disputes reshape relations
The latest tensions are tied to differences over the Iran war and reflect a return to earlier patterns seen at the start of Trump's second term. These developments have renewed debate in Europe over how to respond effectively.Another European diplomat pointed to the approach taken by former German Chancellor Angela Merkel during Trump's first presidency. The diplomat said, "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."
US President Donald Trump Attempts to manage the relationship through a softer approach have not always worked. The same diplomat noted that leaders who tried flattery were also criticised, stating, "All those who tried that got their volley of insults, like the others. So everybody realizes now that flattery doesn't work either." The White House has not issued a response to these remarks.
Renewed pressure on European leaders
Tensions had already been building over the past year. US tariffs, Trump's proposal to acquire Greenland, and a reduction in US support for Ukraine had unsettled relations. In response, leaders such as Keir Starmer, Friedrich Merz and Italian Prime Minister Giorgia Meloni sought to stabilise ties through visits, agreements and policy adjustments, some of which faced criticism at home.However, following the start of the Iran war in February, these efforts have not prevented renewed pressure. Even NATO Secretary General Mark Rutte, often described as effective in managing relations with Trump, was criticised during a White House meeting.
Trump also directed criticism at Giorgia Meloni after she opposed the Iran war and objected to what she described as an "unacceptable" verbal attack on Pope Leo.
Divisions within the United States and Europe
Not all members of the US political system support Trump's approach. Republican Representative Don Bacon criticised the idea of reducing troop levels in Germany, stating that such actions would be counterproductive. He wrote, "The two big airfields in Germany give us great access in three continents. We are shooting ourselves in our own feet."Some of Trump's statements have also surprised European officials. Shortly before comments about troop levels were made public, Germany's top general, Carsten Breuer, had reported positive discussions at the Pentagon regarding Germany's military strategy. He did not indicate any plans for troop reductions.
German officials have remained relatively calm, with a former senior US defense official noting that military cooperation continues. The official said, "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."
Europe reassesses its position
Experts suggest that European leaders are becoming more direct in their responses. Jeffrey Rathke, from the American-German Institute at Johns Hopkins University, observed that Friedrich Merz has become more outspoken in criticising US policy on Iran. He noted that this marks a shift from earlier caution.
Donald Trump has publicly criticised several European leaders in recent days Rathke added that the conflict has direct consequences for Germany, including rising energy costs, making it harder for the public to remain detached from the issue. Despite the tensions, European diplomats emphasise their commitment to maintaining transatlantic relations. However, they acknowledge that adjustments are necessary. One Western diplomat said that Europe can no longer rely on the post-World War status quo and must strengthen its own capabilities, including military power.
Europe faces growing uncertainty as tensions rise, prompting leaders to reassess alliances, strategies, and their reliance on longstanding transatlantic partnerships.
