Charles says there is a “truly unique” relationship between U.K. and U.S.

Charles said that the first British sovereign to visit the U.S. was his grandfather, King George VI, in 1939.

“The forces of Fascism in Europe were on the march, and some time before the United States had joined us in the defense of freedom,” Charles said. “Our shared values prevailed.”

Although we are in a “new era,” he said “those values remain.” But he said this is now a “more volatile and more dangerous than the world to which my late Mother spoke, in this Chamber, in 1991.”

Charles continued to note the partnership, saying the challenges now are too great for any one nation to face alone.
