The Diplomat Season 4 Opens With a Nuclear Heist and a New Prime Minister
The fourth season of The Diplomat begins with a major geopolitical crisis: the U.S. secretly steals a Russian nuclear missile from a submarine off the U.K. coast, bypassing agreed-upon diplomatic solutions. This act fractures the alliance between Kate Wyler and her husband Hal, while British Prime Minister Nicol Trowbridge resigns amid scandal. Jodie Whittaker joins the cast as the new, composed Prime Minister Bethan Vaughn, who refuses to cooperate with Kate’s demands. The season concludes with a shocking G7 summit where President Grace Penn threatens NATO allies, leaving the global order in tatters.
