The Iran nuclear deal, formally known as the Joint Comprehensive Plan of Action (JCPOA), represents one of the most significant diplomatic accords of the 21st century. Signed in July 2015 between Iran and the P5+1 (the United States, United Kingdom, France, Russia, China, and Germany), the JCPOA sought to prevent Iran from developing nuclear weapons while gradually lifting economic sanctions that had crippled its economy. Parallel to governmental and intergovernmental deliberations, institutions like the Council on Foreign Relations (CFR) played a crucial role in informing, analyzing, and influencing public and policy discourse surrounding the JCPOA. As a leading American think tank, the CFR provided policy recommendations, hosted forums, and published analyses that contributed to shaping perceptions about Iran, non-proliferation strategies, and U.S. foreign policy priorities. Therefore, this article provides an in-depth exploration of the JCPOA, followed by a critical examination of the CFR's influence on the Iran nuclear debate.

Origins and Development
Iran's nuclear ambitions date back to the 1950s under the "Atoms for Peace" program, initiated by the United States. However, after the 1979 Islamic Revolution, relations between Iran and the West soured dramatically. The West became increasingly suspicious of Iran's nuclear intentions, particularly as Iran expanded its uranium enrichment capabilities in the 2000s.
Sanctions and Isolation
By the early 2010s, the international community, led by the U.S., imposed severe economic sanctions on Iran, crippling its oil exports, banking system, and economy. These sanctions were designed to bring Iran to the negotiating table.
The Path to Diplomacy
After extensive multilateral negotiations, the JCPOA was finalized in July 2015, representing a significant step toward de-escalation and engagement.
Main Provisions of the JCPOA
Nuclear Limitations
One of the most critical elements of the Joint Comprehensive Plan of Action (JCPOA) was the imposition of strict limitations on Iran’s nuclear program. Iran agreed to reduce its number of operating centrifuges by two-thirds, from approximately 19,000 to around 6,000. These centrifuges, which are essential for uranium enrichment, were limited in both number and type. Moreover, Iran committed to enrich uranium to no more than 3.67%, a level far below the threshold required for nuclear weapons (which is approximately 90%). Therefore, these nuclear restrictions were intended to extend Iran’s “breakout time”, the time it would take to acquire enough fissile material for one nuclear bomb, to at least one year, providing ample time for detection and international response in the event of non-compliance.
Monitoring and Inspections
To ensure Iran’s compliance with these nuclear restrictions, the JCPOA included an unprecedented framework for verification and inspections, spearheaded by the International Atomic Energy Agency (IAEA). The agreement granted IAEA inspectors access to all declared nuclear sites, including continuous surveillance and short-notice inspections. Monitoring mechanisms involved sophisticated technologies such as electronic seals and online enrichment monitors.
Sanctions Relief
In return for Iran’s compliance with the deal’s nuclear restrictions, the United States, European Union, and United Nations agreed to lift a wide range of nuclear-related economic sanctions. This included unfreezing billion of dollars in Iranian assets held abroad and allowing Iran to re-enter global financial and oil markets. Besides, major international banks resumed dealings with Iranian institutions, and foreign companies began reinvesting in Iran’s energy, manufacturing, and aviation sectors.
Initial Impact and Compliance
Economic Recovery
The initial implementation of the JCPOA resulted in a notable recovery in Iran’s economy. Oil exports surged, doubling from 1.1 million barrels per day in 2015 to over 2.3 million by 2017. Major corporations like Airbus, Total, and Siemens began negotiating multi-billion-dollar deals with Iran, signaling growing investor confidence. The Iranian government experienced a boost in revenue, which was used to stabilize the currency, fund infrastructure, and improve social services. Inflation, which had been rampant due to previous sanctions, began to decline.
International Verification
One of the most significant achievements of the JCPOA was the consistent verification of Iran’s compliance by the International Atomic Energy Agency. From 2015 to 2018, the IAEA issued multiple reports confirming that Iran was abiding by the agreed limitations on uranium enrichment, centrifuge numbers, and plutonium production. These reports played a crucial role in sustaining international confidence in the agreement.
Critics and Concerns
Despite its early successes, the JCPOA faced a barrage of criticism from various stakeholders. Critics in the United States, particularly within the Republican Party and among some U.S. allies like Israel and Saudi Arabia, contended that the deal failed to permanently eliminate Iran’s nuclear capabilities and only postponed its potential weapons development. They also objected to the so-called “sunset clauses” that would expire after 10–15 years, potentially allowing Iran to resume sensitive nuclear activities.
U.S. Withdrawal and Re-imposition of Sanctions
Trump Administration’s Decision
In May 2018, President Donald Trump announced the U.S. withdrawal from the JCPOA, labeling it a “disastrous deal” that failed to address Iran’s ballistic missile program, regional behavior, and sunset provisions. The decision marked a sharp reversal from the Obama-era policy of engagement. Trump’s “maximum pressure” campaign reimposed unilateral sanctions on Iran and added new sanctions targeting the Islamic Revolutionary Guard Corps (IRGC), oil exports, and key financial institutions. This move was met with widespread international criticism, as European allies, China, and Russia continued to support the agreement and urged the U.S. to reconsider.
Strategic Fallout
The U.S. withdrawal led to serious strategic consequences, both in the region and globally. Iran, initially remaining in partial compliance, eventually began scaling back its commitments under the JCPOA. It restarted uranium enrichment at higher levels, deployed advanced centrifuges, and stockpiled enriched uranium far beyond the deal’s limits. These actions shortened its breakout time considerably. Unquestionably, tensions between Iran and the U.S. escalated, resulting in military incidents in the Persian Gulf, attacks on oil tankers, and the downing of a U.S. drone. The 2020 assassination of Iranian General Qassem Soleimani by U.S. forces in Baghdad marked a dangerous peak, pushing both nations to the brink of war. The JCPOA’s collapse ushered in a period of heightened instability in the Middle East.
Rising Regional Tensions
Beyond the direct fallout between Iran and the U.S., the unraveling of the JCPOA amplified regional insecurities and deepened the ongoing U.S.-Iran Tensions. Israel intensified its lobbying for stronger international containment of Iran, while Gulf States like Saudi Arabia expressed concerns over Iran’s renewed nuclear activities and its proxy engagements. Moreover, the risk of an arms race in the region increased, as some Arab states began exploring nuclear programs of their own in response to Iran’s capabilities. The diplomatic gains achieved between 2015 and 2017 were quickly eroded, replaced by distrust, brinkmanship, and proxy conflict.
Council on Foreign Relations and the JCPOA
Analytical Support for the JCPOA
The Council on Foreign Relations (CFR), one of the most influential American think tanks, played a vital role in supporting and analyzing the JCPOA. Its scholars published a range of policy briefs, op-eds, and reports that highlighted the strategic merits of the agreement. CFR emphasized that the JCPOA was not perfect but represented the best available option for halting Iran’s nuclear progress without military intervention. By promoting expert insights and realistic assessments, the Council offered policymakers and the public a nuanced understanding of the deal's advantages and limitations.
Policy Influence and Public Debate
CFR significantly shaped public and elite discourse on the JCPOA. Through its flagship journal Foreign Affairs, televised forums, and policy roundtables, it brought together key voices from both sides of the debate. Former Secretary of State John Kerry, Iranian Foreign Minister Javad Zarif, and nuclear experts often participated in CFR events. These discussions helped inform congressional debates and contributed to shaping foreign policy narratives in the mainstream media. CFR also acted as a bridge between academic analysis and real-world policymaking.
Expert Recommendations
Beyond supporting the deal, CFR also offered expert recommendations for improving and extending the agreement. These included proposals for a “longer and stronger” deal that would include stricter sunset clauses, coverage of Iran’s ballistic missile program, and expanded inspections. CFR analysts advocated for continued diplomatic engagement with Iran while maintaining deterrence strategies. The Council also emphasized the need for multilateral frameworks that would involve regional stakeholders, thus embedding the JCPOA within a broader Middle Eastern security architecture.
The Biden Administration and Revival Attempts
- Promises of Re-engagement: President Joe Biden took office with a commitment to restore the JCPOA.
- Diplomatic Challenges: Efforts to revive the deal have faced obstacles, including Iran’s expanded nuclear activities and geopolitical instability.
- CFR’s Updated Insights: CFR has advocated for a “longer and stronger” deal and multilateral diplomacy.
Broader Implications for Non-Proliferation and Regional Security
- Nuclear Non-Proliferation Lessons: The JCPOA was a test case for resolving nuclear disputes through diplomacy.
- Regional Power Balance: Its failure has increased tensions and led to shifts in regional alliances, such as the Abraham Accords.
- Global Diplomacy Norms: The deal’s collapse has raised doubts about U.S. reliability in long-term diplomatic agreements.

Conclusively, the Iran nuclear deal represents a landmark diplomatic achievement and an ongoing policy dilemma. While the JCPOA achieved notable progress in limiting Iran’s nuclear program, its unraveling illustrates the fragility of international agreements in a polarized geopolitical environment. The Council on Foreign Relations has played an important role in informing, shaping, and critiquing U.S. foreign policy toward Iran. As the future of the JCPOA remains uncertain, the continued involvement of informed institutions like CFR will be essential for any successful resolution that balances diplomacy, regional stability, and global security.
