During his tenure, the nation’s top hostage negotiator orchestrated and led negotiations with the Taliban, Syria’s Assad Regime, Venezuela’s Maduro government, the People’s Republic of China, Russia, Belarus, and foreign terrorist organizations to bring home more than 65 American hostages. His work has been hailed across two administrations, and his experience reads like a real-life political thriller. Ambassador Carstens shares the untold stories behind these missions — and what they can teach about navigating chaos, building trust and making decisions with clarity and confidence. The hostage recovery series The Envoy, focused on Ambassador Carstens and his team, is slated for development at Hulu.
