Trump's Deal with Iran vs. Obama's Nuclear Pact: Two Diametrically Opposed Approaches
Donald Trump has signed an agreement with Iran that halts nearly four months of military conflict and reopens the Strait of Hormuz. However, this document is fundamentally different from the Joint Comprehensive Plan of Action (JCPOA) reached by the Barack Obama administration in 2015. The difference is not just in the details — it represents two completely different worldviews in approaching diplomacy.
The new memorandum extends the ceasefire regime for 60 days, while discussions on the nuclear program are postponed to the next stage of negotiations. Thus, Trump has taken a path directly opposite to the logic of the JCPOA, from which he unilaterally withdrew in 2018. While Obama relied on multilateral diplomacy and the immediate lifting of sanctions in exchange for verifiable restrictions, Trump's strategy is "maximum pressure" followed by a truce achieved only after a series of military strikes.
Sequence and Scale: Diplomacy vs. Ultimatum
The main difference lies in the sequence. Obama began with diplomacy and compromise, involving six world powers (the US, UK, France, Germany, Russia, China, and the EU) in the process. His JCPOA, which spanned about 159 pages and took nearly two years to develop, was a complex mechanism of checks and balances. Trump, on the other hand, chose the path of economic and military pressure, reaching an agreement much faster — with mediation from Qatar and Pakistan. His memorandum, signed remotely, is far less detailed but covers a broader range of issues, including shipping security and regional stability.
Nuclear Enrichment: From Compromise to Prohibition
The JCPOA allowed Iran to enrich uranium on its territory up to 3.67% for 15 years, with a limit of 5,060 centrifuges and a stockpile of no more than 300 kg. These frameworks increased the "breakout time" — the period needed to create a nuclear weapon — from a few months to a year. However, critics rightly pointed out that the restrictions were not permanent: after 10-15 years, they began to be lifted. Trump took a stricter approach. His team sought a complete ban on uranium enrichment in Iran, or at least much tougher and longer-term restrictions. After the US withdrawal from the deal in 2018, the limits ceased to apply, and by May 2025, the IAEA recorded Iran possessing over 400 kg of uranium enriched to 60% — making the creation of a nuclear charge possible within days. This fact remains the most explosive point in any future negotiations.
Sanctions and Leverage: "Money Upfront" vs. "Results First"
The Obama administration gave Iran access to the benefits of the deal as quickly as possible: it unfroze Iranian assets and allowed oil exports. The US Treasury estimated that Tehran immediately received about $50 billion. Trump implemented a phased and reversible mechanism for lifting restrictions. Within the 60-day window, the discussion involved approximately $24 billion in frozen funds, but Vance emphasized that this figure is not in the official text, and the money will be transferred only after conditions are met. Sanctions on Iranian oil and petrochemical exports are merely suspended, and European countries have indicated they will lift their restrictions only after verifying compliance with the agreements. Critics of the previous deal argued that the influx of cash strengthened Iran's regional allies. Trump, however, emphasizes that his version involved virtually no upfront payments and was built on concrete results.
As a professional analyst, I see a fundamental paradigm shift here. If Obama's JCPOA was an attempt to "buy time" through complex multilateral compromise, Trump's deal is a bet on coercion and asymmetric leverage. Over the next 60 days, it will become clear whether the "carrot and stick" tactic, with an emphasis on the stick, can lead to long-term stability, or whether it will merely delay an inevitable collapse, as happened in 2018. Markets, especially energy and commodities, will closely watch whether Tehran can retain the right to enrich uranium — this is the main stumbling block that could shatter any fragile peace.
