The publication of Wilson D. Miscamble's latest book, From Roosevelt to Truman: Potsdam, Hiroshima, and the Cold War (New York: Cambridge University Press, 2007), has sparked divergent reactions. Many leading historians have offered high praise for the book, describing it as “the definitive work on the complicated transition from [Franklin] Roosevelt to [Harry] Truman.” Other scholars, however, have faulted Miscamble for being too harsh on Roosevelt and too sympathetic toward Truman. This forum, with commentaries by two prominent scholars, offers contrasting perspectives on the book.
