Six-time U.S. Amb. Ryan Crocker (Career Ambassador and Presidential Medal of Freedom recipient) looks back on his experience working with the military in some of toughest assignments and most fraught conflict zones ever. He also looks to the future and analyzes the nature of expeditionary diplomacy, the current state of geopolitics and the international system, and shares his thoughts on how the Foreign Service might evolve through generational change, namely by talking about diversity, mental health, and work-life balance.  **Brought to you as part of an Una Chapman Cox Foundation project on American diplomacy and the Foreign Service.
