This book presents the first full and systematic account of Iran’s nuclear program from 1979 to 2015. Throughout this time, foreign policy makers, intelligence experts, and scholars on the subject have repeatedly failed to understand the internal dynamics behind Iran’s nuclear project and have underestimated the depth of the regime’s commitment to develop nuclear weapons. The author presents an account of little-understood episodes in the history of the nuclear project, including an analysis of the decision making process of the nuclear sanctum. A full account is given of the organizations that ran the project and a listing of the suppliers that made the project possible. Finally, the book offers a detailed analysis of the international sanctions placed on Iran, including the induced anomie and legitimacy crisis which expedited the decision to rollback.
