UK and EU Push Back Strongly on US Foreign Policy: Can King Charles’ Visit Soften the Transatlantic Divide?

As King Charles III prepares for his state visit to the United States this week, the diplomatic stakes have rarely been higher. What was initially planned as a ceremonial reaffirmation of the “special relationship” between the UK and the US has now become a critical moment for transatlantic unity—one overshadowed by deepening rifts over trade, defense and geopolitical strategy. The visit, scheduled to commence on April 29, 2026, comes at a time when both the United Kingdom and the European Union have openly challenged Washington’s foreign policy decisions, particularly its recent military actions in the Middle East and its approach to NATO burden-sharing.

Laurel Rapp, Director of the US and North America Programme at the London-based think tank Chatham House, described the current climate as “an all-out diplomatic crisis.” In a recent interview with France 24, Rapp noted that the visit—originally intended to celebrate cultural and historical ties—now unfolds against a backdrop of “combative rhetoric” and “unprecedented divide” on key strategic issues, including Iran, Ukraine, and defense budgets. The question looms: Can a royal visit, steeped in tradition and symbolism, help bridge the growing chasm between the US and its closest allies?

The “Special Relationship” Under Strain

The phrase “special relationship” has long been used to describe the close political, military, and economic ties between the US and the UK. Coined by Winston Churchill in 1946, the term has endured through decades of cooperation, from the Cold War to the post-9/11 era. Yet, in recent months, that relationship has faced its most severe test in decades, with disagreements erupting over nearly every major foreign policy issue.

At the heart of the tension is the US’s decision to launch a military campaign against Iran in early 2026, a move that has drawn sharp criticism from both London and Brussels. The UK government, led by Prime Minister Keir Starmer, has publicly expressed “deep concern” over the escalation, even as the EU has gone further, calling for an immediate ceasefire and a return to diplomatic negotiations. In a joint statement issued on April 20, 2026, EU foreign policy chief Josep Borrell warned that the US’s actions risked “further destabilizing an already volatile region” and urged Washington to “reconsider its approach.”

The rift extends beyond Iran. Disagreements over NATO funding have also flared, with the US accusing European allies of failing to meet their defense spending commitments. According to NATO’s latest report, only 18 of the 31 member states met the alliance’s target of spending 2% of GDP on defense in 2025, a figure that has drawn sharp criticism from US officials. Meanwhile, the UK and EU have pushed back against what they describe as Washington’s “transactional” approach to the alliance, arguing that security cooperation should not be reduced to a financial ledger.

Trade, Greenland, and Ukraine: A Web of Disputes

The transatlantic divide is not limited to military and defense issues. Trade tensions have also risen, particularly over the US’s imposition of tariffs on European steel and aluminum exports. The EU has retaliated with its own set of tariffs, and negotiations to resolve the dispute have stalled. Meanwhile, the US’s decision to reopen discussions over Greenland’s potential independence—a move seen as an attempt to counter China’s growing influence in the Arctic—has further strained relations with Denmark and the broader EU.

Ukraine remains another flashpoint. While both the US and its European allies have continued to support Kyiv in its war against Russia, disagreements have emerged over the scope and nature of that support. The US has pushed for a more aggressive military strategy, including the provision of long-range missiles and advanced fighter jets, while the UK and EU have advocated for a more cautious approach, emphasizing the need to avoid further escalation. In a recent speech to the UK Parliament, Foreign Secretary David Lammy warned that “reckless escalation” could lead to “a wider conflict with consequences none of us can afford.”

King Charles’ Visit: Symbolism and Substance

Against this backdrop, King Charles III’s state visit to the US takes on added significance. The visit, which includes stops in Washington, D.C., and Fresh York, is expected to focus on climate change, cultural exchanges, and the promotion of British business interests. However, observers note that the king’s presence could also serve as a diplomatic bridge, offering an opportunity to reset the tone of transatlantic relations.

Rapp, of Chatham House, suggested that the visit could provide a “moment of reflection” for both sides. “The UK and the US share a long history of cooperation, and that history is worth preserving,” she said. “But history alone won’t resolve the current tensions. What’s needed now is a frank conversation about how to move forward—one that acknowledges the differences but also reaffirms the shared values that have long defined the relationship.”

The White House has downplayed expectations for the visit, with Press Secretary Karine Jean-Pierre stating that “the president looks forward to welcoming King Charles and discussing areas of mutual interest.” However, behind the scenes, diplomats on both sides of the Atlantic are reportedly working to ensure that the visit does not become a platform for further public disagreements.

What’s Next for Transatlantic Relations?

The challenges facing the US, UK, and EU are not insurmountable, but they will require sustained diplomatic effort. Analysts suggest that the coming months could see a series of high-level meetings aimed at addressing the most contentious issues, including a potential NATO summit in the fall and renewed trade negotiations between the US and EU.

For now, however, the focus remains on King Charles’ visit and whether it can help ease the current tensions. As Rapp noted, “The visit is a reminder that the transatlantic relationship is not just about governments—it’s about people, culture, and shared history. If there’s one thing that can bring the US and its allies closer together, it’s that.”
