U.S. President Donald Trump announced plans to discuss several significant topics with King Charles during the monarch's state visit to Washington, D.C., starting Monday. The discussions will include NATO, Iran, and the United Kingdom's digital services tax. This visit is particularly notable as it coincides with the 250th anniversary of U.S. independence from Britain. King Charles will also visit Virginia and New York, and deliver a speech before the U.S. Congress. The backdrop of this meeting is marked by the worst relations between the two nations since the 1956 Suez Crisis, with Trump openly criticizing UK Prime Minister Keir Starmer for his refusal to support military action against Iran and making dismissive comments about Britain's military capabilities. Additionally, Trump has threatened to impose tariffs on the UK if the digital services tax remains in place.
