Trump's Deal with Iran vs. Obama's Nuclear Pact: Fundamental Differences in Approaches
Donald Trump signed an agreement with Iran that halts nearly four months of military conflict and reopens the Strait of Hormuz. This document is fundamentally different from the Joint Comprehensive Plan of Action (JCPOA) concluded by the Barack Obama administration in 2015. The differences concern not only tactics but also the very philosophy of negotiations.
Obama's JCPOA was a multilateral agreement that brought together the United States, the United Kingdom, France, Germany, Russia, China, and the EU. In exchange for verifiable limits on Iran's nuclear program, some sanctions on Tehran were lifted. The main emphasis was on containment: negotiators sought clear limits for at least ten years. Obama positioned the deal as a way to buy time. Trump, however, sees his approach as a path to deeper change.
Sequence: From Diplomacy to Pressure
The main difference lies in the sequence of actions. Obama started with diplomacy, while Trump bet on economic and military pressure. He withdrew from the JCPOA in 2018, imposed a maximum pressure campaign, and returned to negotiations only after recent strikes on Iran. The new agreement is a 60-day ceasefire and a framework memorandum, where details of shipping and future nuclear talks are deferred to a second phase.
The scope also differs: Obama's document was about 159 pages long and took about two years to develop. Trump's deal was concluded much faster with the mediation of Qatar and Pakistan, and signatures were affixed remotely. A formal ceremony is planned in Geneva.
Nuclear Enrichment: From Limits to a Full Ban
The JCPOA allowed Iran to enrich uranium domestically to 3.67% for 15 years, with a limit of 5,060 centrifuges and a stockpile of no more than 300 kg. These parameters increased the "breakout time" from two to three months to one year. However, the limits were temporary: after 10 years, restrictions on centrifuges began to be lifted, and after 15 years, on enrichment. It was this part that critics of the JCPOA most often targeted.
Trump took a tougher line. His team sought a complete ban or strict restrictions on uranium enrichment in Iran and insisted on longer timelines. After the US withdrawal from the deal in 2018, the limits ceased to apply. By May 2025, the IAEA recorded stockpiles of over 400 kg of uranium enriched to 60%, making the creation of a nuclear device possible within days. Iran remains the only non-nuclear-weapon state engaging in enrichment at this level.
Sanctions: A Phased and Reversible Mechanism
The Obama administration opened up the benefits of the deal to Iran as quickly as possible: unfreezing assets and allowing oil exports. The US Treasury estimated that Tehran immediately received about $50 billion. The Trump team implemented a phased and reversible mechanism for lifting restrictions. Iranian media mentioned $24 billion in frozen assets, but Vice President Vance refuted this figure, stating it is not in the official text. The money will be transferred only after the terms of the deal are met.
Under the current scheme, sanctions on Iranian oil and petrochemical exports are also suspended, but European countries have indicated they will lift restrictions only after Tehran confirms compliance with the agreements. The 2015 agreement maintained measures related to combating terrorism and human rights violations, easing only nuclear-related sanctions.
Cryptalist Expert Opinion: The ultimate effectiveness of Trump's deal will depend on whether the administration can maintain strict parameters without escalation. History shows that pressure can backfire: it was precisely after the US withdrawal from the JCPOA in 2018 that Iran's nuclear program developed the fastest. The current bet is that fear of military force and economic isolation will force Tehran to make concessions that diplomacy failed to achieve. The next 60 days of negotiations will reveal whether this risk is justified.
