The recent signing of a Memorandum of Understanding (MOU) between President Donald Trump and Iran has reignited discussions about the 2015 Iran nuclear dealknown as the Joint Comprehensive Plan of Action (JCPOA). While both agreements aim to address Iran’s nuclear ambitions, they differ significantly in scope, approach, and outcomes.
President Trump, flanked by key officials including Treasury Secretary Scott Bessent, Secretary of State Marco Rubio, Commerce Secretary Howard Lutnick, and Trade Representative Jamieson Greer, announced the MOU during the G7 Summit in Evian-les-Bains, France, on June 17, 2026. This new agreement comes in the wake of a tumultuous period marked by military conflicts and economic sanctions.
The Nature of the Agreements
The JCPOA was a comprehensive nuclear agreement that involved Iran, the U.S, China, Russia, France, the United Kingdom, Germany, and the European Union. It aimed to limit Iran’s nuclear program in exchange for sanctions relief. In contrast, Trump’s MOU is more of a cease-fire agreement that sets the stage for future nuclear negotiations. It commits Iran to reopening the Strait of Hormuz and includes immediate sanctions relief and the lifting of the U.S. naval blockade.
One of the most notable differences is the absence of a finalized nuclear agreement in the MOU. While the JCPOA included specific commitments to reduce nuclear centrifuges, limit uranium enrichment, and allow IAEA inspections, the MOU leaves the details of the nuclear program to be negotiated within a 60-day period. Iran has committed not to acquire a nuclear weapon, but the enforcement mechanisms are yet to be decided.
Diplomatic Paths and Military Actions
The paths leading to these agreements highlight the differing approaches of the Obama and Trump administrations. The Obama administration engaged in a lengthy, 20-month diplomatic negotiation process to finalize the JCPOA. In contrast, the Trump administration initially pursued diplomacy but ultimately resorted to military action due to the perceived acute threat from Iran.
In, President Trump ordered airstrikes on Iran’s nuclear facilities, setting back the program by up to two years. This was followed by Operation Epic Fury, a joint U.S.-Israel operation aimed at destroying nuclear sites and degrading Iran’s military capabilities. Iran responded by closing the Strait of Hormuz and launching counterattacks against U.S. bases and Gulf nations. The conflict also involved Israel’s war with Iranian proxy forces in Lebanon, resulting in the deaths of 13 American service members and costing the U.S. over $25 billion.
Sanctions Relief and Economic Impact
Both agreements provided significant financial relief for Iran, but the terms and conditions differ markedly. The JCPOA unfroze tens of billions of Iranian funds held overseas, lifted economic sanctions, and allowed Iran’s central bank to operate globally. It also lifted restrictions on Iranian oil exports and included cash transfers of previously seized assets amounting to $1.7 billion. In exchange, Iran agreed to reduce its nuclear centrifuges by two-thirds, commit to not building new enrichment facilities for 15 years, and significantly reduce its stockpile of enriched uranium.
The Trump MOU, on the other hand, lifted oil restrictions and promised to help create a $300 billion reconstruction fund in Iran with regional partners. It also dangled the promise of sweeping sanctions relief if a broader nuclear deal could be reached. However, most of the sanctions relief is contingent on future negotiations that have not yet materialized. In exchange, the U.S. secured Iran’s agreement to open the Strait of Hormuz, a critical economic waterway through which 20% of the world’s oil passes.
Point 5 of the 14-point MOU states that the strait will be toll-free for 60 days, but after that, Iran will work with neighboring Oman to define future administration and maritime services. This leaves the possibility of tolls being introduced in the future, which could impact global oil prices and economic stability.
Selling the Deal
When President Obama announced the JCPOA 11 years ago, he called it the strongest non-proliferation agreement ever negotiated. He acknowledged concerns about the billions in sanctions relief but argued that the deal was the best option to prevent Iran from acquiring a nuclear weapon. Similarly, President Trump praised his MOU, stating it achieved everything we set out to accomplish and more.
However, Trump also admitted that the deal was necessary to avoid economic catastrophe. He conceded that the economic pain resulting from the oil crisis was too risky and that he feared sending the country into a depression. Trump’s remarks highlighted the delicate balance between economic stability and national security, as well as the potential political repercussions of prolonged conflict.
As the world watches the unfolding developments, the question remains: Will Trump’s MOU lead to a lasting peace and nuclear non-proliferation, or will it be seen as a repeat of history? Only time will tell.
