According to a Daily Mail report, British intelligence service MI6 has reportedly warned Prime Minister Keir Starmer that Donald Trump's second White House resembles a mix of the Salem witch trials and the court of Henry VIII. In a classified assessment obtained by the Wall Street Journal, MI6 described the administration as "The Crucible meets Wolf Hall" and instructed its staff to avoid discussing Trump with their counterparts at the CIA. The report matters because it points to unease among Western allies about the reliability and predictability of the United States under Trump.

A separate European intelligence assessment reportedly criticised the unpredictability of US policy, warning that allies were "not dealing with an administration that has processes" but rather "a single volatile individual". Canada, under new Prime Minister Mark Carney, was said to have helped other Western nations rethink their approach to their alliances with the US. The reporting coincides with a NATO summit of all 32 member states in Ankara, Turkey, seen as a test for the alliance, particularly given Trump's frequent criticism of NATO.
