In this startling book, now in paperback, the bestselling author of Explaining Hitler warns that a nuclear World War III is not only the most massive and imminent threat to existence as we know it, but also one of the most ignored. While Russian aggression grows and North Korean nuclear ambitions increase unabated, tensions continue to escalate between India and Pakistan and in the Middle East. Meanwhile, Iran remains committed to developing its nuclear program despite international sanctions. No other writer has assembled the extraordinary array of sources and experiences that Ron Rosenbaum calls on to inform his examination of nuclear war. While working from both historical and contemporary perspectives to explore the people and events that could shape the form of a third world war, he suggests humans have never before been so close to annihilation. In this book, Rosenbaum examines both the paranoia and very real set of possibilities that informs our view of nuclear war and asks whether we can “undream” the nightmare.

The world’s foremost expert on Middle Eastern relations explains Iran’s current nuclear potential and what America can do about it: “Engrossing…If Congress gets a vote on going to war with Iran, let’s hope that this book is on everyone’s reading lists” ( The Economist ). In 2005, Kenneth Pollack’s first book about foreign policy in Iran, The Persian Puzzle , sparked a national conversation, laying out the possible options for nuclear deterrent in Iran. But, despite the attention his solutions received, the world didn’t follow his advice. Now, Iran is even closer to possessing nuclear weapons, and America will have to find a new path forward. In Unthinkable, a New York Times and Economist Best Book of 2013 Pollack explores the intractable American problem with Iran, and Tehran’s pursuit of nuclear weapons capability. With the authority of his years as a CIA analyst and his time as the Director of Persian Gulf Affairs on the National Security Council, Pollack keenly examines the nature of the Iranian threat to American interests and the long-going clash that has led us to this point. Pollack explains and assesses the options for American policymakers: redoubling our efforts at a “carrot-and-stick” approach that combines negotiations and sanctions; aiding the Iranian opposition to bring about a popular form of regime change; an Israeli military strike; the American military option; and containing a nuclear Iran. Ultimately, Pollack argues for an assertive version of containment to maintain pressure on Tehran and minimize its ability to contribute to the problems of the Middle East by keeping it largely on the defensive. “Learned, lucid, and deeply sobering” ( Kirkus Reviews ), Pollack has written one of the most important books on foreign policy in this decade.

Compares certain forms of behavior in German society during the Nazi period in relation to genocide (and actions and reactions in the rest of the world) with American and Soviet behavior in connection with nuclear weapons. Warns that "nuclear professionals" may bring about universal genocide by psychological mechanisms similar to those of the Nazi perpetrators of Jewish genocide. Shows how in both cases there is a totalist, black-and-white ideology in response to trauma; socialization in the killing profession, made possible by "doubling" of identities; the momentum of irreversible progression to ever more inhuman deeds; and dissociation, involving dehumanization of victims and disavowal of the meaning of one's actions. However, in the nuclear arms race, unlike the Holocaust, the potential victims are willing collaborators. Also, in the Holocaust, psychological numbing tended to paralyze the victims and bystanders; along with motives of expediency, this explains the failure of the German public, of world Jewry, and of the Allies to intervene.
