On this installment of ST, we hear from a career foreign service officer about the two largest democracies in Africa, each dealing with conflicts that will continue to have consequences for the U.S. Our guest is Ambassador John Campbell, the Ralph Bunche Senior Fellow for Africa Policy Studies at the Council on Foreign Relations in New York. (Previously, from 1975 to 2007, Ambassador Campbell served as a U.S. Department of State Foreign Service officer, serving twice in Nigeria.) Ambassador Campbell recently gave an address to the Tulsa Committee on Foreign Relations entitled "Nigeria and South Africa: Two Faces of African Democracy," and he expands on his remarks for us today. The second edition of Campbell's book, "Nigeria: Dancing on the Brink," appeared in 2013, and his newest book, "Morning in South Africa," is due out in May. You can learn more about his appearance in Tulsa at this link.
