Following the recent Biden administration announcement that the U.S. would join European nations in seeking to restore the 2015 Iran nuclear deal, we asked several of our Iran experts for their thoughts on the next steps: What should the U.S. goal be for a renewed Iran deal and what suggestions do you have for getting there? Matthew Bunn, Mahsa Rouhi, Sahar Nowrouzzadeh, and William Tobey shared their thoughts.

While U.S. sanctions have caused Iran’s economy major challenges and limited Iran’s access to financial resources, they have not succeeded in changing Tehran’s behavior regarding its nuclear program. Indeed, Iran has not offered additional concessions. Instead, it has engaged in its own leverage-building strategy by ramping up its nuclear activities, missile program, and regional activities. Iran is not only closer to having the capacity to build a bomb, but even the political discourse of key officials on whether to cross that threshold has been shifting.

A Middle East-wide forum could facilitate dialogue and transparency on a range of short-term measures, engendering momentum to then take on other more complex items, such as regional arms control.

Why are governments willing to invest more time in sanctions and war than they do in diplomacy? I pondered this question as the five-year anniversary of the signing of the Joint Comprehensive Plan of Action, or Iran nuclear deal, passed last week. What would relations between the United States and Iran look like had diplomacy been given its due, and the Iran deal honoured for longer?   

An explosion and fire at a workshop at Iran’s Natanz nuclear facility on July 2, which destroyed the better part of an entire building, was followed by a flurry of speculation about the cause. Perhaps a domestic dissident group had planted a bomb, a foreign government had conducted a cyberattack, or an underground gas pipeline simply exploded by accident. Iran’s Atomic Energy Organization announced on July 5 that it had determined the cause, but was withholding that information because of “security considerations.” Still, there is mounting circumstantial evidence that Israel and the United States were involved in what was a deliberate act of sabotage.

An outstanding scholar, extraordinary mentor, and a community builder, Martin Malin passed away on April 19. His warmth, humility, and kindness made him more than a colleague and a close friend to many.

Despite the Trump administration’s assertions, it is increasingly clear that the maximum pressure approach deployed to force Iran to temper its behavior in the Middle East is not working. Iran has allegedly engaged in provocations in the Persian Gulf and has taken concrete steps to scale back its commitments to enrichment limitations under the 2015 nuclear deal. Meanwhile, it hasn’t limited its missile program and has doubled down on its reliance on nonstate actors throughout the region.

The United States and Iran have engaged in a constant raising of the stakes as a means of securing leverage ahead of possible nuclear negotiations. This is a classic bargaining pattern but in the current context, such an approach is particularly risky due to the potential for misperceptions. The complexities of domestic and regional dynamics are also a factor. In such a situation, absent clear understanding of the other’s motivations and tactics, raising the stakes—rather than securing leverage for effective negotiations—could steer the United States and Iran towards a path toward war.

In reaction to a series of escalatory measures by the U.S. government, Iranian leaders faced tough choices: how to most effectively respond to increasing “maximum pressure” from Washington. But the question is why now and in these specific ways?
