From Zero Enrichment to Full Concessions: How the US-Iran MOU Rewrote Every American Red Line

The US-Iran Memorandum of Understanding, signed in Versailles during the G7 summit, represents a significant retreat from Washington’s opening position. A clause-by-clause comparison with the pre-war 2025 document reveals how comprehensively America’s negotiating ground has caved under pressure.

Iran-US Memorandum of Understanding Signed at Versailles: What the Symbolism Tells Us

The place itself had weight. The memorandum of understanding between the United States and Iran was formalized at Versailles, a palace whose name has been synonymous with national humiliation for more than a century. The site was reportedly suggested by French President Emmanuel Macron and signed by Donald Trump.

The treaty that reshaped Europe after the First World War was built on 14 points. The US-Iran memorandum contains 14 clauses. Whether the parallel was intentional or accidental, the optics could not be ignored.

Quick answers to key questions

•5 QUESTIONS

The memorandum of understanding contains 14 clauses that represent a shift in US demands, allowing Iran to retain some uranium enrichment capabilities and delay the immediate removal of stockpiles while delaying a broader sanctions relief.

The signing of Versailles, coupled with historic treaties and national humiliation, underscores the dramatic retreat of US positions and underscores the weight of negotiations between the two nations.

The current MOU lacks the detailed arms control framework of the 2015 agreement and contains weaker language regarding nuclear weapons intent, creating a less stable basis for future negotiations.

The reconstruction fund is intended to support Iran’s economic recovery, but depends on the outcome of further negotiations, with no direct US contribution.

While the MoU aims to provide free navigation initially, it may not guarantee long-term security after 60 days, leaving Iran with the option of charging passage fees and negotiating maritime governance.

However, the document is not a surrender. Diplomatically, it is probably something more important: a formal acknowledgment that the military campaign has not achieved its stated goals.

What the US demanded before the war began

To understand how far Washington has retreated, it is necessary to start with what the Americans originally put on the table. Before Israel, with the active support of the US, launched a 12-day military campaign that culminated in the bombing of Iran’s nuclear facilities, the US presented a document in 2025 that set out its non-negotiable terms.

Those dates were extensive. Iran was to have no domestic enrichment capacity beyond the narrowest permitted uses for medical and agricultural purposes. All nuclear supplies would come from countries outside of Iran. Every gram of enriched uranium stockpile was to be shipped out of Iranian territory immediately after the signing.

All enriched material was to be mixed to 3.67 percent. Iran would be prohibited from building any new enrichment facilities. All programs capable of converting uranium were to be dismantled.

Instead of Iran’s nuclear infrastructure, a consortium comprising Iran, the United States and the Gulf states would handle enrichment at sites located outside Iran entirely.

Red Line by Red Line: What Trump gave at the G7

By the time the G7 met in Évian, these requirements had been substantially revised downwards.

Trump has publicly conceded that Iran has reserved the right to continue enriching uranium, saying it cannot reasonably be ruled out given that other regional states maintain nuclear programs.

The demand for the immediate removal of the enriched stockpile was effectively shelved. U.S. officials have acknowledged that the stockpile could instead be diluted inside Iran itself, under the supervision of the International Atomic Energy Agency, provided it is reduced to 3.67 percent.

The architecture of complex sanctions also began to show cracks. For an immediate exemption from Iranian oil exports to work in practice, the associated financial infrastructure would have to follow.

Broader sanctions relief, including primary and secondary sanctions as well as those imposed by the United Nations, has been delayed until the nuclear negotiations reach a mutually satisfactory conclusion. If the relief is ultimately granted, it would represent the most fundamental reshaping of US-Iranian relations since the 1979 Islamic Revolution.

Strait of Hormuz: A goal that war may not even reach

Perhaps the sharpest irony contained in the memorandum concerns the Strait of Hormuz. Before the outbreak of the conflict, the strait was open. Securing its further passage was essential to America’s justification for supporting military action. The memorandum does not guarantee that it will remain so.

According to the text, free navigation in the strait could end after 60 days, when Iran opens a dialogue with Oman to define future governance and maritime service arrangements in consultation with other Gulf states. Whether this process will preserve the conditions that existed before the start of the war remains entirely uncertain.

The 350 billion reconstruction fund and Iran’s economic reality

The memorandum also includes a proposed $350 billion Iran reconstruction fund. Washington said it would establish the fund but not contribute financially to it.

The equivalent of Iran’s estimated war losses would therefore have to be provided by the Gulf states, some of which had their hotels and air bases bombed during the conflict and whose economies were frozen as a result of the conflict. Whether these states will prove promising is an open question, to say the least.

Even unfreezing the $24 billion in Iranian assets held abroad is unlikely to provide meaningful relief against the scale of Iran’s economic disruption.

Is this deal better or worse than Obama’s 2015 deal?

Analysts familiar with both sets of negotiations cautioned against a direct comparison. The context is fundamentally different, not least because Iran’s nuclear infrastructure has suffered significant physical damage.

Structurally, the 2015 agreement was a fully developed arms control document. The current memorandum is, at best, a framework for further negotiations that could stall or eventually create terms similar to what Obama’s diplomats secured a decade ago.

The language about the intention of nuclear weapons is also weaker. The memorandum acknowledges Iran’s position that it does not seek a nuclear weapon. The 2015 deal included stronger wording, with Iran affirming that “Iran will never seek, develop or acquire nuclear weapons under any circumstances”.

The issue of verification, which is ultimately the only metric that matters in arms control, remains unresolved. A statement of intent carries no weight without a credible control and enforcement regime, and at this point the US memorandum leaves exactly where it began.

Why Trump signed: His own explanation

Trump offered a candid account of his reasoning at his post-G7 news conference. The calculation was economic, not strategic.

“The only president I didn’t want to be was the late, great Herbert Hoover,” he said, referring to a president associated with the Great Depression and the destruction of savings across generations. “I didn’t want to see an economic disaster. If you kept this up, it could have happened.”

The specific pressures Trump cited were a looming global recession and the prospect of oil inventories being critically low within weeks.

Who holds the better hand after a memorandum of understanding?

The memorandum will not close the Iranian nuclear issue. He’s putting it off on terms far less favorable to Washington than he initially demanded. Iran maintains enrichment capacity. His supplies remain on his land. Its influence on the Strait of Hormuz persists. If it were to happen, the sanctions relief would be transformative for Tehran.

Whether Iran won is a question the next round of negotiations will begin to answer. The memorandum makes it clear that the United States did not.
