American Diplomacy is a free, non-partisan, non-profit publication which has focused on foreign policy and the practice of diplomacy since its creation in 1996 by a group of retired Foreign Service Officers in collaboration with the University of North Carolina in Chapel Hill.  In addition to analysis and commentary, the journal includes the insider stories of diplomacy practitioners who served at U.S. missions across the world.
