King Charles' state visit to the United States is seen as the most high-stakes overseas visit of his reign amid strained relations between the U.S. and the UK. Observers predict that the next four days will be a significant test for American-Anglo relations and for King Charles' role in representing his country. The visit comes just days after a gunman stormed the White House Correspondents Dinner that the president was attending. The British ambassador, Sir Christian Turner, highlighted the cultural, historical, economic, and people-to-people links that bind the two countries. The state visit is also an opportunity to re-establish and cement the links and commonalities between the countries during the 250th birthday celebrations.
