This book examines attempts to influence the outcome of the negotiations between Iran and the United States over Iranâ¤s nuclear capabilities. In particular, it focuses on struggles within the United States around public and congressional opinion with regard to the accord. Trying to prevent a successful outcome to the talks became a cottage industry in Washington, with the casino billionaire Sheldon Adelson being just one of those who were pouring millions of dollars into the effort. On the pro-diplomacy side, there were a wide range of religious, peace, and arms control groups with some financial support coming from the Ploughshares Fund trying to create the space for a negotiated agreement. The tactics of both sides of the debate are described and analyzed to show how a contentious foreign policy issue can become not just a decision for high-level government decision makers, but a wide-ranging fight that involves scores of nongovernmental organizations, the media, and thousands of activists.
