The Diplomat is a political thriller created by Debora Cahn that premiered on Netflix in April 2023. Keri Russell stars as Kate Wyler, a career diplomat unexpectedly appointed as US Ambassador to the United Kingdom in the wake of a suspected Iranian attack on a British aircraft carrier that kills 41 sailors. With no diplomatic experience in Europe and a marriage in quiet crisis, Kate must navigate the treacherous waters of international politics while managing the ambitions of those around her.

Set against the backdrop of a geopolitical crisis threatening NATO alliances, the series blends sharp political intrigue with wry humor. Kate's husband Hal Wyler, played by Rufus Sewell, is a seasoned diplomat in his own right whose larger-than-life presence complicates Kate's every move. David Gyasi, Ali Atan, and Nana Mensah round out a stellar ensemble cast that brings Westminster and Washington DC together in a tense dance of power, loyalty, and survival.

The series was a massive hit for Netflix, becoming one of the platform's most-watched English-language series in 2023. The first season's cliffhanger ending left audiences hungry for more, and a second season followed in October 2024, deepening the conspiracies and shaking up the diplomatic landscape. Debora Cahn's background writing for The West Wing shines through in the show's fast-talking, policy-laden dialogue and its belief that intelligence and wit can be deadly weapons in the right hands.
