Points of consensus

▶The JCPOA was negotiated by the Obama administration in 2015, and the United States, under President Donald Trump, later withdrew from the agreement.Jun 2026

▶A core component of the JCPOA was providing Iran with sanctions relief, which unlocked its oil, banking, and trade sectors, in exchange for nuclear concessions.Jun 2026

▶Multiple experts predict that any future nuclear agreement with Iran will likely be structurally similar to the original 2015 JCPOA, focusing on restricting Iran's nuclear program.Jun 2026

▶Under the terms of the JCPOA, Iran agreed to specific limits on its uranium enrichment program, including the quantity and level of enrichment permitted.Jun 2026

Points of debate

▶There is significant disagreement on the effectiveness of the JCPOA, with critics like Donald Trump and John Bolton calling it a failure that enables Iran's nuclear ambitions, while others suggest its collapse strengthened Iranian hardliners.Jun 2026

▶Sources provide conflicting accounts regarding the disposition of Iran's enriched uranium under the deal, with claims that it was shipped to France, that Russia took possession of it, or that it was more generally shipped out or blended down.Jun 2026

▶The exact timeline for negotiating the original agreement is disputed, with different sources citing durations of nearly two years, approximately two and a half years, or a two-year process.

▶The deal's handling of Iran's potential plutonium route to a weapon is a point of contention; one source claims concrete was poured into the Arak reactor core to prevent this, while John Bolton asserts the deal failed to adequately address the plutonium threat from spent fuel at the Bushehr reactor.

Key themes

▶The Original Deal's ArchitectureJun 2026

The 2015 JCPOA was a multifaceted agreement that provided Iran with significant sanctions relief, including a $1.7 billion settlement. In return, Iran accepted limitations on its nuclear program, such as capping uranium enrichment at 3.67%, maintaining a stockpile of no more than 300kg, and submitting to IAEA monitoring.

The deal's structure reveals a transactional approach to non-proliferation, trading economic access for verifiable nuclear constraints, a framework that continues to dominate discussions about future agreements.

▶Criticism and Perceived Flaws

The JCPOA faced harsh criticism, most notably from Donald Trump who called it the "worst deal." Key critiques focused on its failure to address Iran's plutonium pathway via the Bushehr reactor and the existence of "sunset clauses" that would remove most restrictions by 2031, potentially allowing for an industrial-scale enrichment program.

These specific criticisms highlight the core ideological divide in non-proliferation strategy: whether to accept a temporarily constrained Iran or to hold out for a more comprehensive and permanent solution, risking no deal at all.

▶US Withdrawal and its Aftermath

President Trump's 2019 withdrawal from the internationally-endorsed agreement marked a pivotal shift in policy. The consequences included Iran enriching uranium to levels beyond the deal's limits, accumulating a larger stockpile of enriched material than it had while in compliance, and strengthening the position of hardliners within the Iranian regime.

The aftermath of the U.S. withdrawal serves as a case study in the consequences of unilateral policy shifts, demonstrating that dismantling an agreement can lead to a less constrained and more unpredictable adversary.

▶The Path to a New AgreementJun 2026

Discourse on a future deal suggests it will likely resemble the original JCPOA, exchanging sanctions relief for a halt or rollback of uranium enrichment. However, new potential concessions are being discussed, such as a five-year complete halt on enrichment, which was not part of the 2015 agreement, though such a deal would still likely be unacceptable to U.S. allies in the Gulf.

The recurring discussion of a JCPOA-like framework suggests that despite its flaws, it remains the most viable template for diplomatic engagement, with any new deal's success depending on negotiating stricter terms and managing regional partner anxieties.

Timeline

c. 2013-2015

A negotiation period lasting approximately two to two-and-a-half years culminates in the signing of the Joint Comprehensive Plan of Action (JCPOA).

2015

The JCPOA is implemented. Iran agrees to limit its uranium enrichment to 3.67%, ship out or blend down excess uranium, and allow IAEA monitoring in exchange for sanctions relief. Measures are also taken to block the plutonium pathway, such as pouring concrete into the Arak heavy water reactor's core.

2019

The U.S. under President Donald Trump withdraws from the JCPOA, which he characterized as the "worst deal." At the time of the withdrawal, Iran was reportedly enriching uranium to less than 4%.

Post-2019

Following the U.S. withdrawal, Iran is reported to have increased its stockpile of enriched uranium beyond the levels permitted by the original deal. The failure of the agreement is also cited as having strengthened hardliners within Iran.

Present Discourse

Experts and officials discuss a potential new nuclear agreement. Many predict it will resemble the original JCPOA, though new terms, such as a five-year halt on enrichment, are reportedly on the table. Trump has stated any new deal he negotiates will be "far better" than the 2015 agreement.

Notable quotes

“President Trump tore up the JCPOA, the Obama-era Iran nuclear agreement, which had been endorsed by the international community.”

“I mean, in the end, you may have to come back to an agreement that's somewhat similar to the JCPOA, the agreement that the Trump administration pulled out in its first term. Maybe it'll have somewhat different terms, but just trying to restrict the pace at which Iran can develop a nuclear weapons system.”

“The Iranians supposedly agreed, at least for five years, to stop enrichment. They never agreed to that in the Obama JCPOA.”

“Iran currently possesses more enriched uranium than it did when the JCPOA was in effect.”
