The Iran Nuclear Deal: A Definitive Guide has been produced in the interest of contributing to informed Congressional review and public discourse on a comprehensive nuclear agreement with Iran—the Joint Comprehensive Plan of Action (JCPOA). It provides a concise description of the agreement and the accompanying UN Security Council Resolution 2231. It also includes a balanced assessment of the agreement's strengths and weaknesses with respect to its central objective to prevent Iran from acquiring nuclear weapons.

To assist Members of Congress and observers in analyzing these issues and judging a potential comprehensive agreement, the Belfer Center prepared this brief to outline the key facets of sanctions against Iran. Written as an addendum to our April policy brief, ‘Decoding the Iran Nuclear Deal,’ this report is driven by the policy debate’s leading questions.

On April 2, 2015, the E.U. (speaking on behalf of the P5+1 countries) and Iran announced agreement on “key parameters” for a comprehensive agreement on Iran’s nuclear program. The E.U.-Iran Joint Statement is buttressed by unilateral facts sheets issued by the U.S. and Iran, which provide further details of the framework accord. Negotiators now turn to translating this framework accord into a final comprehensive agreement by June 30, 2015. Members of Congress and their staffs, as well as informed citizens, are now focusing on the Iranian challenge and assessing the framework accord. The Belfer Center for Science and International Affairs at the Harvard Kennedy School has prepared this Policy Brief summarizing key facts, core concepts, and major arguments for and against the current deal aimed at stopping Iran from developing nuclear weapons. The purpose of this Policy Brief is not to advocate support for or opposition to the tentative deal that has been negotiated, but rather to provide an objective, nonpartisan summary to inform Members and others in coming to their own conclusions. The team of experts who prepared this report includes Democrats, Republicans, Independents, and internationals, who have many disagreements among themselves but who agree that this Brief presents the essentials objectively.

The Secretary of Energy on December 20, 2013 established the Secretary of Energy Advisory Board (SEAB) Task Force on Nuclear Nonproliferation (TFNN) and charged it to “advise the DOE on future areas of emphasis for its nuclear nonproliferation activities by addressing the following questions:

1. What are the current and likely future challenges to nuclear nonproliferation?

2. What should DOE be doing to help the United States Government prepare to meet those challenges?

3. What are DOE’s current areas of emphasis in nuclear nonproliferation?

4. In what ways should DOE’s nuclear nonproliferation efforts be modified and/or expanded?

5. What obstacles stand in the way of making the recommended changes in DOE’s nuclear nonproliferation activities, and how might they be overcome?”

Even as this paper was being written and edited, U.S.-Russian relations have warmed and chilled. Today, as we are about to go to press, marks a particularly chilly period in recent history, with the cancellation of a planned Moscow Summit in September 2013. To some, this cold spell might signal an inapt moment to consider issues related to transcending mutual deterrence. Such a view would overlook the aims of the paper, which attempts to assess the central and enduring interests of the United States and Russia, the extent to which they coincide or conflict, and whether or not in light of these interests mutual deterrence should remain a fundamental feature of the relationship.

The Belfer Center hosted a half-day conference on March 23, 2017, gathering a group of top-level American and Japanese academics to discuss the US-Japan alliance and the rise of China. The event was well attended by scholars and students of Harvard and nearby universities, including a large group of scholars from the US Naval War College. Other notable attendees included policy officials as well as members of the Japanese Consulate in Boston.
