Trump's Deal with Iran vs. Obama's Nuclear Pact: Two Worlds, Two Strategies
The signing of a memorandum of understanding between the US and Iran, ending nearly four months of military conflict and reopening the Strait of Hormuz, is fundamentally different from the 2015 nuclear pact reached by the Obama administration. This is not just another diplomatic round—it is a paradigm shift.
The new agreement, signed by Donald Trump, Vice President JD Vance, and Iranian Parliament Speaker Mohammad-Bagher Ghalibaf, establishes a 60-day ceasefire regime. Discussion of the nuclear program has been postponed to the next phase of negotiations. This stands in stark contrast to the Joint Comprehensive Plan of Action (JCPOA), from which the US withdrew in 2018.
Sequence and Scale: Two Opposing Approaches
Obama's JCPOA was a multilateral agreement uniting the US, UK, France, Germany, Russia, China, and the EU. The strategy was based on containment: Iran was allowed to enrich uranium to 3.67% for 15 years under strict IAEA oversight, with a limit of 5,060 centrifuges and a uranium stockpile of no more than 300 kg. It was a compromise designed for a decade, with gradual lifting of restrictions. Obama positioned the deal as a way to buy time.
Trump chose a different tactic: withdrawal from the JCPOA, a maximum pressure campaign, and forcing negotiations through economic and military leverage. His agreement is not a 159-page document developed over two years, but a quick, targeted memorandum negotiated remotely with Qatar and Pakistan as mediators. The key difference is sequence: Obama started with diplomacy, Trump bet on force.
Uranium and Sanctions: Rigidity vs. Flexibility
At the heart of the disagreement is the issue of enrichment. The JCPOA allowed it, but within strict limits, increasing the time Iran would need to build a nuclear weapon from 2-3 months to a year. Critics of Obama's pact pointed to the "sunset clauses": after 10 years, limits on centrifuges would begin to lift, and after 15 years, restrictions on enrichment would expire.
The Trump team took a tougher line, pushing for a complete ban or strict restrictions on enrichment. After the US withdrawal from the deal in 2018, the limits ceased to apply. By May 2025, the IAEA recorded uranium enriched to 60% exceeding 400 kg—enough to create a warhead in a matter of days. Iran remains the only non-nuclear-weapon state engaging in enrichment at this level.
The sanctions regime also differs. Obama quickly unfroze Iranian assets (the US Treasury estimated them at ~$50 billion). Trump implemented a phased and reversible mechanism: $24 billion in frozen funds, according to Iranian media, will only be transferred after the deal's conditions are met. European countries have indicated they will lift restrictions only after verification.
Frameworks and Leverage: The Future Beyond the Horizon
The JCPOA dealt exclusively with the nuclear program, ignoring the missile program and regional proxies like Hezbollah. Trump demands that these aspects be included in the new agreement, linking progress to the unblocking of the Strait of Hormuz and overall regional security.
The differences are clear: Obama bet on multilateral compromise, Trump on pressure and tougher, longer-term conditions. Critics warn that it was precisely after the US withdrawal from the JCPOA in 2018 that the Iranian program developed most rapidly. The next 60 days of negotiations will reveal whether the bet on force can yield more than conventional diplomacy, especially given Trump's threats against Kharg Island.
Cryptalist Analysis: The oil market and global logistics chains have already reacted to the news of the ceasefire and the reopening of the strait. However, for long-term investors in energy and commodity assets, the key factor remains not so much the signing itself, but the sustainability of the new regime. Iran, retaining the ability to enrich rapidly, keeps a powerful lever of influence. The current deal is not the finale, but merely a tactical pause in the geopolitical game.
