Britain's King Charles III made a historic visit to the US to commemorate Britain's loss in the war of independence. Despite facing potential pitfalls from US President Donald Trump, Charles delivered a message of unity and celebration of the "eternal bond" with America. He challenged Trump on several issues the US and UK have clashed over in recent months, including the principle that executive power is subject to checks and balances. The King also emphasized the collective strength of the long-standing alliance and stressed the importance of the transatlantic alliance. Despite these challenges, King Charles also used his visit to boost NATO, a move that he believes will help rebuild US-UK ties.
