Through interviews and eyewitness accounts, declassified security documents and underground pamphlets, Kurzman documents the overwhelming sense of confusion that gripped pre-revolutionary Iran, and that characterizes major protest movements. His book provides a striking picture of the chaotic conditions under which Iranians acted, participating in protest only when they expected others to do so. Indeed, only when large numbers of Iranians began to think the unthinkable, in the words of the U.S. ambassador, did revolutionary expectations become a self-fulfilling prophecy. A corrective to 20-20 hindsight, this book reveals shortcomings of analyses that make the Iranian revolution or any major protest movement seem inevitable in retrospect.
