This study explores how a nuclear-armed Iran would behave and what this would entail for the United States and its main regional allies. It analyzes the Islamic Republic's ideology, motivations, and national security doctrine; examines a nuclear-armed Iran's potential policies toward Saudi Arabia and the GCC; discusses its potential behavior toward Israel; explores its relations with terrorist groups; and presents key findings.

Examines Iran's current nuclear potential while charting America's future course of action, recounting the prolonged clash between both nations to outline options for American policymakers.

The War Against the Terror Masters is a must-read guide to the terrorist crisis. Michael A. Ledeen explains in startling detail how and why the United States was so unprepared for the September 11th catastrophe; the nature of the terror network we are fighting--including the state sponsors of that network; the role of radical Islam; and the enemy collaboration of some of our traditional Middle Eastern "allies";--and, most convincingly, what we must do to win the war. The War Against the Terror Masters examines the two sides of the war: the rise of the international terror network, and the past and current efforts of our intelligence services to destroy the terror masters in the U.S. and overseas. Ledeen's new book also visits every country in the Near East and describes the terrorist cancers in each. Among many revelations that will attract wide attention: *How the terror network survived the loss of its main sponsor, the Soviet Union. *How the FBI learned from a KGB defector--twenty years before Osama's bin Laden's murderous assault--of the existance of Arab terrorist sleeper networks inside the United States. *How moralistic guidelines straight-jacketed the FBI from even collecting a file of newspaper clippings on known terror groups operating in America. *How the internal culture of the CIA, and severe limitations on its ability to operate, blinded us to the growth of terror networks. And much more.

This volume assumes the worst: a defensive, aggressive Iran already possesses a nuclear arsenal. How should the United States handle this threat, and can it deter the use of such weapons? Through three scenario models, this study explores the political, strategic, and operational challenges facing the United States in a post–Cold War world. The authors concentrate on the type of nuclear capability Iran might develop; the conditions under which Iran might resort to threatened or actual weapons use; the extent to which Iran’s military strategy and declaratory policy might embolden Iran and its proxies to pursue more aggressive policies in the region and vis-à-vis the United States; and Iran’s ability to transfer nuclear materials to others within and outside the region, possibly sparking a nuclear cascade. Drawing on recent post–Cold War deterrence theory, the authors consider Iran’s nuclear ambitions as they relate to its foreign policy objectives, domestic politics, and role in the Islamic world, and they suggest specific approaches to improve U.S. defense and deterrence planning.

Iran's nuclear program is one of this century's principal foreign policy challenges. Despite U.S., Israeli, and allied efforts, Iran has an extensive enrichment program and likely has the technical capacity to produce at least one nuclear bomb if it so chose. This study assesses U.S. policy options, identifies a way forward, and considers how the United States might best mitigate the negative international effects of a nuclear-armed Iran.

"The Institute of Science and International Security’s new book Iran’s Perilous Pursuit of Nuclear Weapons chronicles the Islamic Republic of Iran’s efforts to build nuclear weapons. The book draws from original Iranian documents seized by Israel’s Mossad in 2018 in a dramatic overnight raid in Tehran. The “Nuclear Archive” allows deep insight into the country’s effort to secretly build nuclear weapons. The book relies on unprecedented access to archive documents, many translated by the Institute into English for the first time. The first part of the book concentrates on Iran’s crash nuclear weapons program in the early 2000s to build five nuclear weapons and an industrial complex to produce many more. By 2003, responding to growing pressure from European powers to freeze its publicly known nuclear programs and fearing a possible U.S. military attack, Iran’s leaders decided to downsize, but not stop, their secret nuclear weapons effort. The second part of the book discusses Iran’s nuclear path post-2003, revealing a careful plan to continue nuclear weapons work, overcome bottlenecks and better camouflage nuclear weapons development activities. Since 2003, the Islamic Republic’s nuclear scientists and weaponeers have concentrated on establishing capabilities to make weapon-grade uranium and developing more reliable, longer-range ballistic missiles."--Publisher description.

What does it mean for Iran to have nuclear weapon capabilities? And what should the United States do about this threatening situation?
