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.

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

Little more than a year ago, the Nonproliferation Policy Education Center (NPEC) completed its initial analysis of Iran's nuclear program, Checking Iran's Nuclear Ambitions. Since then, Tehran's nuclear activities and public diplomacy have only affirmed what this analysis first suggested: Iran is not about to give up its effort to make nuclear fuel and, thereby, come within days of acquiring a nuclear bomb. Iran's continued pursuit of uranium enrichment and plutonium recycling puts a premium on asking what a more confident nuclear-ready Iran might confront us with and what we might do now to hedge against these threats. These questions are the focus of this volume. The book is divided into four parts. The first presents the endings of the NPEC's working group on Iran. It reflects interviews with government officials and outside specialists and the work of some 20 regional security experts whom NPEC convened in Washington to discuss the commissioned research that is contained in this book. Some of this report's endings to keep Iran and others from overtly deploying nuclear weapons or leaving the Nuclear Nonproliferation Treaty (NPT) are beginning to gain official support. The U.S. Government, the International Atomic Energy Agency (IAEA), and an increasing number of allies now support the idea that states that violate the NPT be held accountable for their transgressions, even if they should withdraw from the treaty. There also has been increased internal governmental discussion about the need to clarify what should be permitted under the rubric of "peaceful" nuclear energy as delineated under the NPT. The remaining report recommendations, which were presented in testimony before Congress in March of 2005, remain to be acted upon.

Considering the latest Iranian nuclear developments, one might question whether a study now on how best to restrain Tehran is simply one that's come too late. To be sure, estimates vary as to when Iran could build its first bomb. Some believe Tehran could do it before the end of 2005; others think Iran would only be able to do so by the end of the decade. In either case, though, the die seems cast: If Iran wants, it has all that it needs eventually to build a bomb on its own. Certainly, trying to deny Iran further nuclear technology in the hopes that this will prevent it from getting nuclear weapons is no longer a credible strategy. The questions this edited volume addresses are whether or not any strategy can prevent Iran from going nuclear, what the proper goals of such a strategy might be (deterring use, keeping Tehran from deploying weapons, getting it to dismantle its nuclear program, etc.), and what other nonproliferation goals ought to be attempted (including trying to dissuade other nations from following Iran's example). The answers this volume offers are: 1) in the long-run Iran will gain little from going nuclear, and 2) much can be gained by enforcing the nonproliferation rules Iran agreed to and spelling out the costs to Iran of its continuing acquisition of nuclear weapons- related capabilities.

The first detailed Iranian account of the diplomatic struggle between Iran and the international community, The Iranian Nuclear Crisis: A Memoir opens in 2002, as news of Iran's clandestine uranium enrichment and plutonium production facilities emerge. Seyed Hossein Mousavian, previously the head of the Foreign Relations Committee of Iran's Supreme National Security Council and spokesman for Tehran's nuclear negotiating team, brings the reader into Tehran's private deliberations as its leaders wrestle with internal and external adversaries. Mousavian provides readers with intimate knowledge of Iran's interactions with the International Atomic Energy Agency and global powers. His personal story comes alive as he vividly recounts his arrest and interrogations on charges of espionage. Dramatic episodes of diplomatic missions tell much about the author and the swirling dynamics of Iranian politics and diplomacy—undercurrents that must be understood now more than ever. As intense debate continues over the direction of Iran's nuclear program, Mousavian weighs the likely effects of military strikes, covert action, sanctions, and diplomatic engagement, considering their potential to resolve the nuclear crisis.
