Obama's Nuclear Pact vs. Trump's Deal: Two Eras, Two Philosophies of Pressure
The signing of the memorandum between Donald Trump and Iran marked a turning point, halting nearly four months of military conflict and reopening the Strait of Hormuz. However, this document is not merely a copy of the 2015 nuclear pact. It represents a fundamentally different approach, reflecting a paradigm shift in American diplomacy.
Barack Obama's Joint Comprehensive Plan of Action (JCPOA) united six world powers and the European Union. It was based on the idea of deterrence through compromise: Iran would limit its nuclear program in exchange for sanctions relief. Negotiations lasted nearly two years, and the document itself was about 159 pages long. Obama's deal was designed for decades, with a phased lifting of restrictions.
The Road to the Deal: Diplomacy vs. Ultimatum
Trump chose a directly opposite strategy. He withdrew from the JCPOA in 2018, imposed a policy of "maximum pressure," and only returned to negotiations after a series of military strikes on Iran. His approach is pressure as a precondition. Instead of multilateral consultations, there were bilateral contacts mediated by Qatar and Pakistan. Instead of years of negotiations, a quick memorandum was agreed upon remotely.
The key difference lies in the sequence: Obama started with diplomacy, Trump with an economic and military ultimatum. The 2026 deal only formalizes a 60-day ceasefire, postponing nuclear issues to the next stage.
Uranium Enrichment: The Red Line and the Apple of Discord
The JCPOA allowed Iran to enrich uranium up to 3.67% for 15 years, with a limit of 5,060 centrifuges and a stockpile of no more than 300 kg. These constraints increased the "breakout time" to a nuclear weapon from a few months to a year. Critics rightly pointed out that after 10-15 years, the restrictions would weaken.
After the US withdrawal from the deal in 2018, Iran sharply accelerated its program. By May 2025, the IAEA had recorded over 400 kg of uranium enriched to 60% — a level close to weapons-grade. With such volumes, creating a warhead became a matter of days. Trump demands a complete ban or strict limits on enrichment within the country, which for Tehran is a matter of national sovereignty.
Sanctions: The Carrot and Stick Have Switched Places
The Obama administration quickly unfroze Iranian assets (estimated by the US Treasury at around $50 billion) and allowed oil exports. The Trump team implemented a phased and reversible mechanism: sanctions are suspended, but not lifted. Vice President Vance emphasized that funds would only be transferred after the terms of the deal are met. European countries also made it clear they would lift restrictions only after verification.
Critics of the JCPOA argued that the influx of funds strengthened Iran's regional allies. Trump, however, builds his deal on results, not on advances.
Geopolitical Framework: From Nuclear Narrowness to Regional Security
The JCPOA dealt exclusively with the nuclear program, ignoring ballistic missiles and support for entities like Hezbollah. Trump's memorandum links progress to the unblocking of the Strait of Hormuz and overall regional security. This is a fundamental expansion of the agenda.
Supporters of the previous deal warn that pressure could backfire, as it did in 2018 when the Iranian program accelerated the fastest. The next 60 days will reveal whether a bet on force can achieve more than classic diplomacy, especially amid Trump's threats against Kharg Island.
Expert opinion: Markets, including the cryptocurrency market, are closely watching this process. Stability in the Strait of Hormuz is a direct factor for oil prices and, consequently, for macroeconomic liquidity. If Trump's deal proves sustainable, we will see a reduction in the geopolitical premium in risk assets. If the pressure triggers a new round of escalation, volatility will return with a vengeance.
