When King Charles III and Queen Camilla stepped onto the tarmac at Joint Base Andrews on Monday, the pageantry of the moment—red carpets, military bands, the exchange of pleasantries—belied the diplomatic minefield ahead. This is not the first time a British monarch has visited an American president in a time of tension. But as contemporary political historian Anthony Seldon put it, this visit carries a degree of difficulty
that vastly surpasses any since George VI’s 1939 meeting with Franklin D. Roosevelt on the eve of World War II. The difference? Roosevelt was a known quantity. Donald Trump is not.
The Unpredictable President and the Monarch’s Leeway
Trump’s admiration for the British monarchy is well-documented. He has called Charles a brave man, and he’s a great man
, and his public demeanor during the visit—smiles, handshakes, the obligatory small talk—suggests a leader eager to project warmth. But beneath the surface, the risks are acute. Trump’s political rhetoric has repeatedly clashed with the values Charles is expected to uphold: the rule of law, separation of powers, and the Enlightenment principles that underpin both nations’ constitutions. When Trump dismisses UK aircraft carriers as toys
compared to American military might, or when he criticizes Prime Minister Keir Starmer in the same breath as praising the King, the contradictions are glaring.
Seldon’s assessment is revealing: Charles, he argues, is probably the one person in the world who Trump doesn’t want to offend
. This dynamic creates an unusual advantage. Trump, Seldon suggests, will operate within tramlines
, ceding the monarch a rare degree of control. But how far can Charles push? The historian frames the choice starkly: the King could opt for caution, delivering a scripted address that avoids controversy. Or he could use the platform to remind the American people of the basis on which the United States was formed 250 years ago
—a not-so-subtle rebuke of Trump’s authoritarian leanings.
The question is whether Charles will seize the moment. The White House’s YouTube highlight reel from Trump’s recent 60 Minutes interview—where the president angrily denied being a pedophile, rapist, and traitor
in response to an assassination attempt—offers a glimpse of the volatility Charles must navigate. Trump’s defensiveness on the Epstein scandal, his long-standing ties to the late financier, and his tendency to lash out at critics all underscore the tightrope the monarch must walk. One misstep, one perceived slight, and the carefully constructed diplomatic tramlines could collapse.
Historical Parallels and the Weight of Precedent
The last time a reigning British monarch visited the United States during a period of transatlantic strain, the world was on the brink of war. George VI’s 1939 meeting with Roosevelt was a masterclass in soft diplomacy, using shared history and personal rapport to secure American support against Nazi Germany. The stakes were existential, but the players were predictable. Today, the threats are more diffuse—climate change, the rise of authoritarianism, the erosion of democratic norms—but the diplomatic playbook is far less clear.
Seldon points to other fraught moments in US-UK relations: Lyndon B. Johnson’s clashes with Harold Wilson over Vietnam, Richard Nixon’s strained interactions with Edward Heath, and the Suez Crisis, which ended Anthony Eden’s premiership. Each of these episodes tested the special relationship, but none involved a president as mercurial as Trump. The historian’s verdict is blunt: Because you are dealing with somebody who is so unpredictable,
the visit is obviously beyond tricky
. Yet he also notes that there have been tense moments in the past. And it will be fascinating to see how the monarch plays it.

The shadow of Jeffrey Epstein looms large over this visit. Charles’s brother, Prince Andrew, remains a liability, his ties to the disgraced financier a persistent embarrassment. While Queen Camilla is scheduled to meet with domestic abuse campaigners—a deliberate counterpoint to the Epstein scandal—the King’s refusal to engage with survivors risks being perceived as a snub. In a political climate where Trump’s own associations with Epstein are under renewed scrutiny, the optics are fraught. The White House’s decision to highlight Trump’s 60 Minutes interview, despite its explosive content, only heightens the tension.
The Starmer Factor: A Government’s Gamble
For Keir Starmer’s government, this visit is a calculated risk. Philip Murphy, director of history and policy at the University of London, argues that the real danger lies not with Charles but with the UK’s political leadership. It’s another aspect of this desperate desire to court Trump and to take really significant risks,
he says. They’ve risked the prestige of their head of state, they’ve put his dignity in peril by putting him in contact with Trump, who is both hugely controversial and a very tricky person to deal with in public.
The controversy surrounding Peter Mandelson and Olly Robbins—former Labour advisors whose roles in Brexit negotiations remain contentious—has already strained relations with the White House. Starmer’s government is walking a fine line: eager to reset US-UK ties after years of post-Brexit turbulence, but wary of being seen as too deferential to Trump. The King’s visit is a diplomatic olive branch, but it also exposes Starmer to criticism from both sides of the Atlantic. If Charles’s address to Congress strikes the wrong tone—too conciliatory or too critical—it could undermine the prime minister’s efforts to rebuild trust with Washington.
Darren Jones, the chief secretary to the prime minister, has downplayed security concerns following the recent shooting at the White House correspondents’ dinner. There’ll be appropriate security in place in relation to the risk,
he told the BBC. But the incident underscores the volatility of the moment. Trump’s rhetoric—his attacks on the media, his dismissal of political violence as sick
when directed at him but not when his supporters are involved—has created an environment where even ceremonial events carry real danger.
The Monarch’s Toolkit: Protocol, Symbolism, and Shared History
Charles’s greatest asset may be the very institution he represents. The monarchy’s role in diplomacy is not to engage in partisan politics but to embody continuity, tradition, and shared values. This visit is no exception. The King’s schedule—meetings with veterans, climate activists, and cultural figures—is designed to highlight areas of cooperation that transcend political divides. His address to Congress, a rare honor for a foreign leader, will be scrutinized for every nuance. Will he emphasize the long-term US and UK friendship
, as royal sources have suggested? Or will he subtly remind his audience of the separation of powers, with the bill of rights at its heart
, as Seldon hinted?
The challenge is to strike a balance: firm enough to uphold democratic principles, but diplomatic enough to avoid provoking Trump’s ire. The King’s personal rapport with the president—Trump has said, I know him well, I’ve known him for years
—could be an asset, but it is also a liability. Any perceived favoritism risks undermining Charles’s neutrality, a cornerstone of the monarchy’s role in British politics.
What remains unclear is how Charles will handle the more contentious aspects of the visit. Will he address the Epstein scandal directly, or will he let Queen Camilla’s engagements with abuse survivors speak for themselves? Will he use his platform to advocate for climate action, a cause he has championed for decades, even if it clashes with Trump’s environmental policies? The answers will determine whether this visit is remembered as a diplomatic triumph or a missed opportunity.
An Open Question: What Comes Next?
As Charles and Trump pose for photographs in the White House Rose Garden, the symbolism is undeniable. Two leaders, each representing institutions under strain, each navigating a moment of profound uncertainty. The King’s visit is a reminder that diplomacy is not just about policy—it is about people, about history, about the stories nations tell themselves. But it is also a test. Can Charles use his unique position to steer the conversation toward shared values, or will he be constrained by the very unpredictability that defines this moment?
The answer will reverberate far beyond this week’s ceremonies. If the visit succeeds, it could lay the groundwork for a renewed US-UK partnership, one built on mutual respect rather than transactional politics. If it fails, it could deepen the fractures in an already fragile relationship. Either way, the stakes could not be higher. For Charles, for Starmer, and for the future of the special relationship, this is a moment that demands more than pageantry. It demands purpose.
