(SeaPRwire) –   During a rare address to the United States Congress on Tuesday, King Charles III lauded the shared history of the two nations while offering subtle critiques of several policies pursued by President Donald Trump.

Receiving multiple standing ovations from both legislative chambers, Charles noted that his visit commemorates the 250th anniversary of the American colonies’ declaration of independence, highlighting a transatlantic relationship spanning four centuries.

“I am the nineteenth in our line of Sovereigns to study, with daily attention, the affairs of America,” the King remarked.

Dressed in a pinstripe suit and a light blue tie, Charles described the “special” bond between the nations as a narrative of “reconciliation, renewal, and remarkable partnership.”

“From the bitter divisions of 250 years ago, we forged a friendship that has grown into one of the most consequential alliances in human history,” he stated, emphasizing the resilience of an alliance that has faced significant pressure since the outbreak of the Iran war.

While affirming the U.K.’s “highest regard and friendship” for the U.S., he also reminded Washington of its global influence and pointed to areas where the two countries diverge.

“America’s words carry weight and meaning, as they have since independence,” he said. “The actions of this great nation matter even more.”

Charles underscored the necessity of the North Atlantic Treaty Organization (NATO) and its mutual defense commitments. He also made a pointed reference to the limitations on executive authority inherent in British and American legal traditions, tracing them back to the 13th-century Magna Carta.

Furthermore, the King advocated for “unyielding resolve” in supporting Ukraine and, drawing on his long-standing commitment to conservation, urged both nations to embrace a “shared responsibility to safeguard nature.”

The following details outline these key issues and where the King’s perspective differs from that of President Trump.

Importance of NATO

Following the September 11, 2001, terrorist attacks, the U.K. and the broader NATO alliance supported the U.S. by deploying troops alongside American forces in Afghanistan, the site where the attacks were orchestrated.

This remains the only instance in which the mutual defense clause of Article 5 has been triggered.

“Your pain and shock were felt around the whole world,” Charles said. “We answered the call together—as our people have done so for more than a century, shoulder to shoulder.”

The King is scheduled to visit the 9/11 Memorial in New York City on Wednesday to honor the victims.

Charles emphasized that the transatlantic alliance remains vital.

“That partnership is more important today than it has ever been,” he added.

His defense of the alliance follows recent threats from President Trump to withdraw the U.S. from NATO amid tensions resulting from the Iran war.

Limits on executive power

Charles highlighted that American founding ideals are rooted in English legal tradition, specifically “the principle that executive power is subject to checks and balances.” This concept originated with the 1215 Magna Carta, signed at Runnymede to address the tyrannical behavior of King John.

The King noted that the Magna Carta has been referenced in at least 160 U.S. Supreme Court rulings since 1789.

His comments, which were met with applause from Congress, come at a time when President Trump has frequently utilized executive authority to deploy military and Border Patrol personnel into U.S. cities, bypassed Congressional oversight regarding federal spending, and utilized investigations against political opponents.

Defending Ukraine

Since returning to office last year, President Trump and his Republican allies have expressed growing dissatisfaction with the financial burden of supporting Ukraine’s defense against the Russian invasion.

King Charles, who hosted Ukrainian President Volodymyr Zelensky at Buckingham Palace in March, has consistently supported Ukraine’s resistance to Russian aggression.

During his speech, the King encouraged Congressional Republicans to maintain U.S. military aid to Ukraine.

Referencing the global support the U.S. received after 9/11, Charles addressed House Speaker Mike Johnson, stating: “Today, Mr. Speaker, that same unyielding resolve is needed for the defense of Ukraine and her most courageous people.”

Protecting nature

Known for his decades of environmental advocacy, Charles issued a subtle appeal for President Trump and the Republican party to prioritize the protection of natural ecosystems.

Since his return to the White House, President Trump has withdrawn the U.S. from the Paris Climate Agreement, rescinded various air and water quality regulations, and moved to permit oil drilling on public lands.

“Our generation must decide how to address the collapse of critical natural systems,” Charles said. “We ignore at our peril the fact that these natural systems—in other words, nature’s own economy—provide the foundation for our prosperity and our national security.”
