Points of consensus

▶The Joint Comprehensive Plan of Action (JCPOA) was a 2015 agreement negotiated under the Obama administration, from which the U.S. later withdrew under President Trump.Apr–May 2026

▶The agreement imposed specific limitations on Iran's nuclear activities, including capping uranium enrichment levels at 3.67% and limiting the total stockpile to 300 kilograms.Apr 2026

▶Negotiating the JCPOA and subsequent related deals is a complex and lengthy process, with both the original agreement and later attempts taking approximately two years.Apr 2026

▶The fundamental structure of any potential future agreement is expected to resemble the original JCPOA, involving Iran restricting its nuclear program in exchange for the lifting of U.S. sanctions.Apr 2026

Points of debate

▶There are conflicting accounts regarding the disposition of Iran's enriched uranium under the 2015 deal, with one claim stating it was shipped to France for conversion and another claiming Russia took possession of it.Apr 2026

▶Experts hold contrasting views on the JCPOA's long-term efficacy; some emphasize its success in disabling pathways to a weapon, like pouring concrete into the Arak reactor, while others criticize its 'sunset clauses' that would eventually remove most restrictions by 2031.Apr 2026

▶There is a debate over whether a new deal can be substantially better than the original, as asserted by President Trump, or if any future agreement will inevitably be similar, focusing on restricting the pace of development rather than eliminating the program entirely.Apr 2026

▶The nature of Iranian concessions is a point of contrast between the original deal and current negotiations. The 2015 JCPOA permitted limited enrichment, whereas current talks reportedly include a five-year halt on all uranium enrichment, a concession not previously offered.Apr 2026

Key themes

▶JCPOA Mechanics and RestrictionsApr 2026

The original 2015 agreement contained highly specific technical limitations on Iran's nuclear program. These included pouring concrete into the Arak heavy water reactor's core to block a plutonium pathway, limiting uranium enrichment to 3.67%, and capping the stockpile at 300 kilograms.

The technical specificity of the original deal provides a clear baseline for analysts to measure any deviations or new concessions in current or future negotiations, making it a critical reference point for assessing progress.

▶The Agreement's Lifecycle: Withdrawal and ConsequencesApr–May 2026

The JCPOA, endorsed by the international community, was unilaterally abandoned by the U.S. under President Trump in 2019. Following the withdrawal, Iran has reportedly increased its stockpile of enriched uranium beyond the levels permitted when the deal was in effect.

The U.S. withdrawal demonstrates the fragility of international agreements tied to executive power, creating a precedent that likely increases Iran's demand for more durable guarantees in any future negotiations.

▶Sunset Clauses and Long-Term ViabilityApr 2026

A significant criticism of the JCPOA centers on its 'sunset clauses.' Key restrictions were set to begin expiring in 2025, with nearly all limitations being removed by 2031, which critics argue would have allowed Iran to develop an industrial-sized enrichment program.

The approaching expiration dates of these clauses create a time-pressure dynamic, forcing policymakers to either renegotiate a more permanent solution or accept the eventual legitimization of a larger Iranian nuclear program.

▶The Future of a Nuclear DealApr 2026

Discourse on a new agreement suggests it will likely mirror the JCPOA's core trade-off: sanctions relief for nuclear restrictions. However, new potential concessions, such as a five-year halt on enrichment, are reportedly on the table, while key U.S. allies in the Gulf may find even a JCPOA-like deal unacceptable.

The negotiation landscape has shifted, with Iran potentially offering more significant short-term concessions while the geopolitical opposition from regional allies presents a major hurdle that did not derail the original 2015 agreement.

Changes over time

c. 2013-2015

The original JCPOA is negotiated over a period of approximately two to two-and-a-half years.

2015

The JCPOA is signed. As part of the agreement, Iran's enriched uranium is transferred to Russia and concrete is poured into the Arak heavy water reactor.

2019

The U.S., under President Trump, withdraws from the JCPOA. At the time of withdrawal, Iran was enriching uranium to a level below 4%.

Post-2019

Following the U.S. withdrawal, Iran's stockpile of enriched uranium grows to exceed the amount it possessed while the JCPOA was in effect.

c. 2024-2026

New negotiations are underway, with reports that Iran has offered new concessions not present in the 2015 deal, such as a five-year halt on uranium enrichment.

2025-2031

The original JCPOA's 'sunset clauses' are scheduled to begin expiring in 2025, with most restrictions being removed by 2031, a key point of contention for critics.

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

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

“Probably they stop are forced to stop enriching uranium. They probably get some pause over some period of time. And the U.S. probably ends up lifting some of these sanctions, which looks a lot like the JCPOA that President Obama did.”

John Lieber · Bloomberg Surveillance TV: April 24th, 2026 | Bloomberg Surveillance

“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.”
