Jeff Glor talks to historian Fredrik Logevall about his new book, "Embers of War," which traces how the twentieth century conflict in Vietnam drew in all the world's powers, led to the demise of France's colonial empire, and embroiled the United States in an unavoidable quagmire. Logevall is John S. Knight Professor of International Studies and professor of history at Cornell University, where he serves as director of the Mario Einaudi Center for International Studies.
