President Donald Trump began his state visit to the United Kingdom this week, prompting the largest security operation in Britain since the King's coronation. The security measures, involving drones, snipers, sniffer dogs, helicopters, mounted police, and River Thames boat teams, are being bolstered by armed police from across Britain deployed to London and Windsor. US authorities can apply for Secret Service officers to carry firearms during the visit, according to operational firearms commander Dan Hatfield. The heightened security considerations are partly attributed to the recent shooting of Charlie Kirk and an attempted assassination of the President last year. Thames Valley Police are reportedly preparing for the three-day trip. The visit occurs as China has issued a strong warning, stating Beijing would respond with "decisive measures" if NATO nations, influenced by the U.S., introduce tariffs targeting Russian oil, a move previously called for by President Trump. China's Foreign Minister Wang Yi had privately communicated to European officials in early July that China could not afford for Russia to lose the war in Ukraine, as it would allow the U.S. to focus its attention on China. This development follows the arrests of Adib Nasir, 58, and Adil Justice Ahme Nasir, 31, in Salt Lake City on September 15th, 2025, for allegedly placing an unexploded device under a Fox 13 news vehicle near the site of Charlie Kirk's murder. U.S. Representative Michael Fine of Florida's 6th District announced his office will seek the termination, defunding, and license revocation of any Florida government employees or licensed professionals celebrating Charlie Kirk's death. In separate international news, the UK and the US finalized five commercial nuclear deals valued at over £51 billion, aimed at enhancing nuclear energy research and reducing reliance on Russian nuclear materials by 2028.
