Anne-Marie Slaughter, President and CEO of New America Foundation and former directory of policy planning for the U.S. Department of State

“Seminar XXI was a pivot point in my career, opening my eyes more widely to the interconnections in the global world. I loved every minute of the yearlong experience, which provided me with deep intellectual capital that I drew on as a four-star admiral and NATO commander and still use today as dean of the Fletcher School.”

James Stavridis, Dean of the Fletcher School, Tufts University
