King Charles III has called on the United States to maintain strong unity with its Western allies, warning that growing global tensions over Iran and Ukraine are putting transatlantic relations under pressure.
He made the appeal on Tuesday during a rare address to the U.S. Congress, where he stressed that cooperation between the United States and its allies remains essential in addressing major global challenges.
Without directly engaging in political disputes between President Donald Trump and UK Prime Minister Keir Starmer, the monarch emphasised that the long-standing relationship between both nations remains resilient despite past disagreements.
Charles highlighted that no single country can effectively confront today’s global issues alone, urging deeper collaboration on security, diplomacy, and international stability.
A major focus of his address was the war in Ukraine, where he called for strong and sustained international commitment to achieving a lasting peace amid Russia’s ongoing invasion.
His speech came during a high-profile state visit marking 250 years since American independence, an event that also underscored the historical ties between the United Kingdom and the United States.
President Donald Trump, who hosted the royal visit, described the UK as America’s closest ally and praised the so-called “special relationship” between both nations during a reception at the White House.
The visit included ceremonial events such as military honours, a flypast, and meetings with top U.S. officials, reflecting the symbolic importance of the diplomatic engagement.
Despite earlier tensions between the two governments over international policy differences, the tone of the visit remained largely cordial and celebratory.
In his remarks, King Charles also referenced shared democratic traditions, highlighting the legal and constitutional foundations that continue to link both countries.
He further emphasised the importance of accountability in governance and the principle of checks and balances as a cornerstone of democratic systems.
The monarch also noted the deep cooperation between the two nations in defence, intelligence, and security, describing it as a vital element of global stability.
The visit is expected to conclude with a formal state dinner, rounding off a diplomatic engagement that combined ceremony with discussions on pressing international issues.
