The details of his study of negotiation options with Iran are classified, but Bueno de Mesquita says that the broad outline is that there is nothing the United States can do to prevent Iran from pursuing nuclear energy for civilian power generation. The more aggressively the U.S. responds to Iran, he says, the more likely it is that Iran will develop nuclear weapons. The upshot of the study, Bueno de Mesquita argues, is that the international community needs to find out if there is a way to monitor civilian nuclear energy projects in Iran thoroughly enough to ensure that Iran is not developing weapons.
