In November 2007, the U.S. National Intelligence Council issued an NIE entitled Iran's Nuclear Intentions and Capabilities that contained a surprising finding. Analysts concluded that Iran had probably suspended its clandestine effort to develop a nuclear weapon. This assessment created a political firestorm, despite the fact that analysts went to great lengths to assess the accuracy of their sources and to offer nuanced judgments about the complex issues surrounding Iran's civilian and military nuclear programs. In this edited volume, former intelligence professionals and leading intelligence scholars describe and assess the factors that shaped this NIE and the course of events that sparked an international controversy. These chapters make a valuable contribution to the understanding of the state of the art when it comes to intelligence analysis and the challenges that emerge when intelligence estimates address significant foreign and defence policy issues and on-going political debates.

One of the chapters in this volume was originally published in the book titled, Routledge Companion to Intelligence Studies, edited by Robert Dover, Michael Goodman, Claudia Hillebrand. Other chapters were originally published in the journals Intelligence and National Security and Comparative Strategy.
