— More than 100 former U.S. ambassadors, career and political alike, and from both parties, who signed a similar public letter endorsing the deal. It begins, “The Joint Comprehensive Plan of Action (JCPOA) with Iran stands as a landmark agreement in deterring the proliferation of nuclear weapons.”
— More than 60 American “national-security leaders”—politicians, military officers, strategists, Republicans and Democrats—who issued their own public letter urging Congress to approve the deal. E.g., “We congratulate President Obama and all the negotiators for a landmark agreement unprecedented in its importance for preventing the acquisition of nuclear weapons by Iran.” Here are a few Republicans who signed this letter: former Special Trade Representative Carla Hills; former Treasury Secretary Paul O’Neill; former Senator Nancy Landon Kassebaum. Here are a few Democrats: former Secretary of State Madeleine Albright; former Senate Majority Leader George Mitchell; former Defense Secretary William Perry.
— Hans Blix, the former head of the International Atomic Energy Agency, who a dozen years ago tried to avert the disaster in Iraq. He says of the deal, “I think it is a remarkably far-reaching and detailed agreement. And I think it has a potential for stabilizing and improving the situation in the region as it gradually gets implemented.”
— A number of Iranian dissidents, who say that the deal could shift the internal balance in their country.
