[Kaplan] distinguishes himself with tight, journalistic accounts of what one might term the 'high nuclear politics' of D.C. policy makers, military men, public intellectuals and government officials, especially as they quarreled behind closed doors. Mr. Kaplan pulls together tales from candid interviews with participants, while also drawing on declassified (and often eye-popping) documents from presidential libraries, Department of Defense files and State Department records. His notes on sources—there is, alas, no bibliography—pay little attention to scholarly monographs on U.S. foreign and nuclear policy. Mr. Kaplan’s forte is with the primary stuff, not the secondary literature.
