Nuclear About-Face: Examining the Role of Collective Face Concerns in Iran's Nuclear Decision-Making

| July 2023

By looking beyond solely Iran’s security motivations, this paper by Sahar Nowrouzzadeh seeks to inform more holistic negotiation strategies that can potentially influence Iran’s nuclear decision-making in a manner more favorable to U.S. interests.

Iran's Atomic Archive: Lessons Learned for Export Controls and Inspections

| August 2021

The Wisconsin Project on Nuclear Arms Control hosted two roundtables—in September 2019 and March 2021—to identify lessons that should be drawn from the archive of Iranian documents seized by Israel in 2018, related to the effectiveness of export controls, monitoring measures such as international inspections, and other efforts to prevent material and expertise from reaching programs to develop nuclear weapons. Informed by these lessons, the group sought to develop a set of findings and recommendations to support the policymaking and monitoring communities.

The Deal That Got Away: The 2009 Nuclear Fuel Swap with Iran

| January 2021

With concerns and uncertainties regarding Iran’s nuclear future persisting to this day, this paper seeks to review the TRR negotiations and the context in which they unfolded in order to capture some of the lessons of negotiating with Iran regarding its nuclear program, primarily from the viewpoint of senior U.S. officials involved at the time. The paper is also informed by the personal perspective of one of the authors (Poneman) who led the U.S. delegation in the 2009 Vienna talks, and who, prior to this publication, had not publicly elaborated on his experience. The other author (Nowrouzzadeh), who supported the TRR talks in an analytical capacity within the U.S. Department of Defense, also conducted an extensive interview with Poneman as part of their collaboration on this paper. By drawing on existing literature and recent interviews with several senior U.S. officials involved in the negotiations now that over ten years have passed, the authors seek to draw useful lessons from this episode that can assist policymakers in understanding Iran’s nuclear decision-making and in their continued efforts to shape the future trajectory of Iran’s nuclear program.

The Iran Nuclear Archive: Impressions and Implications

In mid-January, a team of scholars from the Belfer Center’s Intelligence and Managing the Atom Projects traveled to Tel Aviv, Israel to examine samples of, and receive briefings on, an archive of documents related to Iran’s nuclear weapons program. The large cache includes some 55,000 pages of documents and a further 55,000 files on CDs that included photos and videos. A clandestine Israeli intelligence operation spirited the materials out of Iran in early 2018.

The documents that the Belfer group were shown confirm that senior Iranian officials had decided in the late 1990s to actually manufacture nuclear weapons and carry out an underground nuclear test; that Iran’s program to do so made more technical progress than had previously been understood; and that Iran had help from quite a number of foreign scientists, and access to several foreign nuclear weapon designs. The archive also leaves open a wide range of questions, including what plan, if any, Iran has had with respect to nuclear weapons in the nearly 16 years since Iran’s government ordered a halt to most of the program in late 2003. 

This brief report summarizes the group’s conclusions about what the archive reveals about Iran’s program and questions that remain open.

When Did (and Didn’t) States Proliferate?

| June 2017

In this Project on Managing the Atom Discussion Paper, Philipp C. Bleek chronicles nuclear weapons proliferation choices throughout the nuclear age. Since the late 1930s and early 1940s, some thirty-one countries are known to have at least explored the possibility of establishing a nuclear weapons program. Seventeen of those countries launched weapons programs, and ten acquired deliverable nuclear weapons.

Is Iran Mass Producing Advanced Gas Centrifuge Components?

| May 30, 2017

The head of Iran’s nuclear program says Iran has the capability to initiate mass production of advanced centrifuges on short notice. The mass production of these centrifuges (or their components) would greatly expand Iran’s ability to sneak-out or breakout to nuclear weapons capability or surge the size of its centrifuge program if the deal fails or after key nuclear limitations end. If Salehi’s statement is true, Iran could have already stockpiled many advanced centrifuge components, associated raw materials, and the equipment necessary to operate a large number of advanced centrifuges. The United States and the International Atomic Energy Agency (IAEA) need to determine the status of Iran’s centrifuge manufacturing capabilities, including the number of key centrifuge parts Iran has made and the amount of centrifuge equipment it has procured. They need to ensure that Iran’s centrifuge manufacturing is consistent with the intent of the nuclear deal as well as the deal’s specific limitations on advanced centrifuges. Moreover, the Iranian statement illuminates significant weaknesses in the Iran deal that need to be fixed.

Iran and a New International Framework for Nuclear Energy

| November 2016

As early as the end of the Second World War it was recognized that nuclear fuel cycle technologies developed for military purposes—specifically, uranium enrichment and reprocessing—had major potential for peaceful applications but remained inherently dual-purpose, and if not controlled appropriately, could be diverted to military use. The very first issue considered by the newly founded United Nations was “the problems raised by the discovery of atomic energy.”

Tipping the Balance?

| December 2015

Standing before the United States Congress early in March 2015, in the face of a looming deadline in the Iran and P5+1 talks over the Iranian nuclear program, Israeli Prime Minister Benjamin Netanyahu portrayed the negotiations in stark terms. Drawing a direct parallel between biblical plots to persecute Jews in pre-Islamic Persia and modern Iran’s nuclear program, Netanyahu framed Iran as nothing less than an existential threat to Israel. Anything short of a practical dismantling of Iranian nuclear infrastructure would be unacceptable. Largely perceived as an attempt to undermine President Barack Obama’s efforts to reach a negotiated settlement with Iran, Netanyahu’s actions thus proved quite contentious inside the United States.

Strengthening the Verification and Implementation of the Joint Comprehensive Plan of Action

| November 16, 2015

The Joint Comprehensive Plan of Action (JCPOA) puts Iran’s nuclear program under greater scrutiny than before and reduces the likelihood of an overt dash to the bomb for the next 10 years. But the agreement contains a number of notable weaknesses—particularly regarding undeclared nuclear activity and weapons- related research—that should be mitigated by adopting stronger verification measures.

IAEA Visit to the Parchin Site

| September 22, 2015

On September 21, 2015, IAEA Director General Yukiya Amano informed the Board of Governors that one day earlier he had visited a suspect site within the Parchin Military Complex in Iran. A few days prior to Director General Amano’s visit, as foreseen in an unofficial draft Iran/IAEA agreement, Iran, took environmental samples at the suspect location. Amano said in a public statement that access to the site was important in order to “clarify issues related to possible military dimensions to Iran’s nuclear program.” However, the manner in which environmental samples were taken raises troubling precedents for both the IAEA’s investigation into Iran’s past work on nuclear weapons and the verifiability of the long term nuclear deal, the Joint Compreheansive Plan of Action (JCPOA).
