King Charles defends NATO and Ukraine in Congress address, drawing standing ovation
WASHINGTON, DC: In only the second address by a British sovereign to a joint meeting of the US Congress, King Charles III delivered a forceful defense of the Western alliance on Tuesday, April 28, pointedly reminding American lawmakers of the vital role NATO has played in protecting the United States.
Speaking from the same rostrum where his mother, Queen Elizabeth II, stood in 1991, the King utilized the historical gravity of the moment to counter recent skepticism from the White House regarding the necessity of transatlantic military cooperation.

From the depths of the Atlantic to the disastrously melting ice caps of the Arctic, the commitment and expertise of the United States Armed Forces and its Allies lie at the heart of NATO.

The monarch’s address arrived at an "inflection point" for the 250-year-old relationship between the two nations.
Since returning to office in January 2025, President Donald J Trump has repeatedly criticized NATO for its perceived lack of involvement in the US-Israeli conflict with Iran, at times threatening a total American withdrawal from the organization.
Charles, however, chose to center his remarks on the "commitment and expertise" of the alliance, arguing that the security of North Americans and Europeans is inextricably linked through their "common adversaries."
Monarch defends Article 5 legacy
In a direct reference to the "special relationship," King Charles reminded the chamber that the first and only time NATO invoked Article 5, the collective defense clause stating an attack on one is an attack on all, was in response to the September 11 attacks on New York and Washington.
By highlighting this moment of need, the King reminded that the alliance is not a one-way street of American support, but a "pledged" mutual defense that has historically safeguarded US interests when they were most vulnerable.

In the immediate aftermath of 9/11, when NATO invoked Article 5 for the first time and the UNSC was united in the face of terror, we answered the call together, as our people have done so for more than a century.

"The commitment and expertise of the United States Armed Forces and its allies lie at the heart of NATO," Charles declared, positioning the alliance as a "final deal" for global stability.
The monarch’s comments appeared to be a calculated response to the administration's stand on treaty obligations, suggesting that a move toward isolationism would be a "strategic disarray" for both continents.
His defense of the alliance was met with visible support from many lawmakers who have expressed concern over the president’s recent "maximum friction" with European capitals.
King Charles urges aid to Ukraine in speech
Turning to the ongoing conflict in Eastern Europe, the King delivered a sobering reminder of the need for sustained aid to Kyiv.
He praised the "most courageous people" of Ukraine and argued that the same "unyielding resolve" that defeated tyranny in the 20th century is required today to secure a "truly just and lasting peace."
The message was a possible nudge to President Trump, who has frozen nearly all military assistance to Ukraine since January 2025, claiming he can act as an impartial broker to end the war.
The mention of Ukraine triggered a massive standing ovation from a bipartisan majority in the chamber, a rare display of legislative independence from the White House’s current policy.
Charles argued that defending Ukraine against "unprovoked aggression" is a moral credibility issue that mirrors the existential struggles of the Cold War and the World Wars.

For many in the room, the King’s words served as a "discovery" of the lingering congressional appetite for a "total reset" of the administration's aid freeze.
King Charles condemns Washington Hilton shooting in opening remarks
The King opened his address by referring to the Saturday night shooting at the Washington Hilton, which took place just blocks from the venue.
He described the incident as an attempt to “foment wider fear and discord” and to “harm the leadership of your nation,” condemning the violence in clear terms. He added that such actions would not achieve their intended impact in a democratic system.

His remarks came as 31-year-old Cole Tomas Allen of Torrance, California, appeared in court on Monday, facing charges linked to the attempted assassination of the president.
The incident briefly cast uncertainty over the state visit, though President Donald J Trump stated that the visiting delegation would remain “very safe.”
The King also acknowledged the role of security personnel and public servants, noting their continued efforts in maintaining stability during such incidents. His comments underscored a broader message on institutional resilience and the importance of safeguarding democratic processes in the face of threats.
