Donald Trump has reached an agreement with Iran that ends four months of conflict and allows ships to pass freely through the Strait of Hormuz again. This new deal is significantly different from the 2015 nuclear agreement negotiated by Barack Obama.
This new deal continues the current truce for another two months, but puts off discussions about Iran’s nuclear program until a later date. It’s structured very differently from the original JCPOA agreement – the one former President Trump withdrew from in 2018.
Two Deals Built on Opposite Logic
The JCPOA, negotiated during the Obama administration, involved an agreement between the United States, Britain, France, Germany, Russia, China, and the European Union. Under the deal, Iran agreed to restrict its nuclear program in a way that could be verified, and in exchange, many international sanctions were lifted.
The main aim at the time was to control the situation. Those involved in talks hoped to establish clear, provable restrictions that would last for at least ten years.
Obama sold the JCPOA as a way to buy time. Trump casts his approach as a path to lasting change.
Unlike previous administrations, Trump pulled out of the agreement in 2018 and instead pursued a policy of strong economic sanctions against Iran. This new deal was ultimately achieved following recent military actions targeting Iranian interests.
The order of approaches taken by these presidents differed significantly. Obama prioritized diplomatic solutions, whereas Trump favored using economic and military strength to gain advantages.
Reports describe a 60-day ceasefire, with a framework covering navigation and future nuclear talks.
The two agreements also differed in scope and timeline. The Obama agreement was a lengthy document, around 159 pages, and took approximately two years to complete. The Trump agreement, however, was reached more quickly, with help from countries like Qatar and Pakistan acting as go-betweens.
After extensive negotiations, we’re happy to share that the United States and Iran have reached a peace agreement. Both countries have agreed to immediately and permanently stop all military actions in all areas, including…

After reaching an agreement through remote discussions, a formal signing ceremony will take place in Geneva. Donald Trump, Vice President JD Vance, and Mohammad-Bagher Ghalibaf, the speaker of the Iranian parliament, will all sign the agreement.
Enrichment sits at the center
The JCPOA agreement allowed Iran to enrich uranium within its own borders, but limited the enrichment level to 3.67 percent for fifteen years. The deal also restricted Iran to using a maximum of 5,060 centrifuges and maintaining a stockpile of up to 300 kilograms of enriched uranium, all while being closely inspected.
The restrictions placed on Iran extended the time it would take to develop a nuclear weapon from a few months to over a year.
The agreement included time limits on certain restrictions. Limits on centrifuges were lifted after 10 years, and those on enrichment after 15. Many critics considered these automatic expirations the deal’s biggest flaw.
The Obama-era Iran Deal was widely criticized. Here’s a breakdown of some key concerns:
Sunset Clauses: The agreement included time limits – between 10 and 15 years – on restrictions related to Iran’s nuclear program. After these limits expired, Iran was allowed to resume industrial-scale enrichment, significantly reducing the time it would take them to potentially build a nuclear weapon. Some of those expiration dates began last year.
Sanctions Relief: As part of the deal, economic sanctions against Iran were lifted…

Trump prefers the opposite approach. His administration has been advocating for either completely stopping Iran from enriching uranium within its borders or severely limiting the process, along with extending and strengthening existing restrictions.
Following the withdrawal from the agreement in 2018, previous restrictions were lifted. By May 2025, the International Atomic Energy Agency (IAEA) reported that Iran had over 400 kilograms of uranium enriched to 60 percent – a level significantly exceeding the terms of the original deal.
Iran recently achieved a key milestone in uranium enrichment – getting very close to having enough material for a nuclear weapon within just a few days. This also makes Iran unique among countries without existing nuclear weapons, as it’s the only one currently enriching uranium to that level.
As an analyst, I remember that the 2015 agreement linked access for inspections to a quick restoration of UN sanctions if Iran didn’t uphold its commitments. This ‘snapback’ tool was designed to rapidly reimpose penalties if we detected any violations.
Iran insists on its right to enrich uranium internally, and this position continues to be the biggest obstacle to reaching an agreement.
Currently, the 2026 agreement doesn’t address what to do with Iran’s enriched uranium. Discussions in the next few weeks will determine the future of that stockpile.
How Trump’s Iran Deal Reshapes Sanctions Relief
As a researcher studying this agreement, I found that the Obama administration prioritized immediate benefits for Iran. Specifically, the deal allowed Iran to regain access to frozen assets and resume oil exports. While some critics claimed around $100 billion would be accessible, our analysis of US Treasury estimates suggests the figure was closer to $50 billion.
Trump designed the aid package in stages, with the possibility of it being taken back. Reports from Iranian media say around $24 billion in previously frozen assets were released as part of a 60-day agreement.
Vance challenged that number, stating it isn’t mentioned anywhere in the document. A U.S. official added that no funds will be transferred until all requirements are met.
There’s a lot of misinformation circulating about a possible agreement regarding the Strait and Iran’s nuclear program. To clarify, Iran isn’t receiving any money just for signing an agreement or even showing up to talks. Any funds will only be released based on specific actions taken as part of the deal…

The existing agreement temporarily removes sanctions on Iran’s oil and petrochemical sales. European countries have indicated they will only end these measures if Iran demonstrates clear, provable progress on key commitments.
As a researcher studying the 2015 agreement, I’ve found that it didn’t alter existing penalties related to terrorism or human rights. The agreement specifically focused on easing restrictions tied to nuclear programs – those were the only measures changed.
Some people disliked the original agreement because they believed it gave financial support to groups allied with Iran in the Middle East. President Trump describes his approach as focusing on results rather than providing immediate money, and avoiding large upfront payments.
According to The Hill, Donald Trump stated that any agreement he reaches with Iran will be a strong and legitimate one, unlike the previous deal negotiated by Barack Obama. He criticized the earlier agreement for providing Iran with substantial funds and essentially allowing them to pursue nuclear weapons. Trump claims his approach would be completely different.
Scope, Leverage, and the Road Ahead
The Iran nuclear deal, known as the JCPOA, was limited in scope. It only dealt with Iran’s nuclear activities and didn’t address issues like its missile programs or support for groups in other countries.
The 2015 agreement didn’t address ballistic missiles or groups like Hezbollah very much. President Trump insists any new agreement must deal with these issues.
Trump has connected his strategy to larger goals, suggesting that progress depends on reopening the Strait of Hormuz and addressing overall security issues in the region.
The contrast is clear:
- Obama bet on multilateral compromise, while
- Trump bet on pressure and a stricter, longer-lasting settlement.
Iran and Washington have also floated different readings of the terms.
- Tehran has stressed its enrichment rights, while
- The US officials point to firmer limits ahead.
Those who favored the original agreement caution that pushing Iran too hard could have unintended consequences. They point out that Iran made the most progress with its nuclear program after the United States withdrew from the deal in 2018.
As an analyst, I’m closely watching the next two months of negotiations. We’ll see if this new approach, which prioritizes leveraging pressure, can achieve results where traditional diplomacy fell short. The situation is particularly sensitive given the heightened tensions following the previous administration’s threat regarding Kharg Island – that really changed the game.
Over the next few weeks, we’ll see if increasing pressure can lead to better terms than those originally agreed upon by President Obama.
