NDU and NDU Foundation collaborate to bring global diplomatic experts to broaden the learning experiences of students and faculty. Last week, Marie Yovanovitch, former U.S. Ambassador to Ukraine, joined NDU faculty, staff, and students for a moderated discussion on Ukraine and her new book, Lessons from the Edge: A Memoir. Here's a book review. AMB.Yovanovitch is a Senior Fellow in the Russia and Eurasia Program at the Carnegie Endowment for International Peace at Georgetown University.
