The Joint Comprehensive Plan of Action (JCPOA), commonly known as the Iran nuclear deal, is on life support. While the United States and Iran have engaged in indirect talks in Vienna, the agreement's core terms have been violated by both sides. Iran now enriches uranium at 60% purity, far beyond the 3.67% limit set by the deal, and the Biden administration has yet to lift key sanctions. The question is whether the deal can be revived and what it would take to fix it.
What Happened to the JCPOA?
The JCPOA was signed in 2015 between Iran and the P5+1 (US, UK, France, Russia, China, Germany). It limited Iran's nuclear activities in exchange for sanctions relief. However, in 2018, President Donald Trump withdrew the US and reimposed sanctions, prompting Iran to gradually breach its commitments. By 2021, Iran had exceeded uranium enrichment levels and stockpile limits. The Biden administration has sought to rejoin, but talks have stalled over key issues like the order of sanctions removal and Iran's nuclear steps.
Current Status: Escalation and Stalemate
As of early 2025, Iran's uranium enrichment at 60% is a significant concern, as it is a short step from weapons-grade 90%. The International Atomic Energy Agency (IAEA) has reported that Iran has enough enriched material for multiple nuclear bombs if further enriched. Meanwhile, the US has maintained most Trump-era sanctions, while Iran has expanded its nuclear program. The Vienna talks have been suspended since September 2022, with no clear path forward.
“The window for diplomacy is closing,” said a senior US official, speaking on condition of anonymity. “Iran’s nuclear advances are making it harder to return to the deal’s limits.”
What Would It Take to Fix the Deal?
Reviving the JCPOA would require mutual concessions. For the US, it means lifting all sanctions that are inconsistent with the deal, including those on oil exports, banking, and shipping. For Iran, it must roll back its nuclear program to 2015 levels: reduce enrichment to 3.67%, cap stockpiles at 300 kg of low-enriched uranium, and allow IAEA inspections. However, both sides have hardened positions. Iran demands guarantees that future US administrations won’t withdraw again, while the US insists on addressing Iran’s ballistic missile program and regional activities, which were not part of the original deal.
Impact of a Collapse
If the deal dies, Iran could quickly develop a nuclear weapon, triggering a regional arms race and increasing the risk of military conflict. Israel has threatened preemptive strikes. The global economy would also suffer, with oil prices spiking due to disrupted supply. Diplomatic credibility of the US and its allies would be damaged, making future nonproliferation efforts harder.
According to a 2024 report by the Arms Control Association, “Without a diplomatic solution, the world faces a choice between a nuclear-armed Iran or a war to prevent it.”
Possible Alternatives
Some experts suggest a “less for less” interim deal, where Iran freezes its enrichment at 60% in exchange for limited sanctions relief. Others propose a broader agreement that includes ballistic missiles and regional proxies. However, neither side has shown flexibility. The US Congress has also imposed new sanctions, complicating executive action.
The path to fixing the deal remains narrow. It requires political will from both capitals and a willingness to compromise. Without it, the JCPOA may become a relic of a failed diplomatic experiment.
