Points in the interim MoU

The United States and Iran are preparing to sign a historic 14-point memorandum of understanding (MoU) in Switzerland this Friday, aiming to end more than 100 days of direct military conflict. The interim agreement establishes a 60-day window for complex technical negotiations regarding the dismantling of Iran's highly enriched uranium stockpiles, the phased lifting of economic sanctions, and the reopening of the Strait of Hormuz to international shipping.[1][5][6]

Speaking on the sidelines of the G7 summit in Evian-les-Bains, France, President Donald Trump delivered a stark ultimatum regarding Tehran's nuclear ambitions. Defending the unreleased text of the MoU after a bilateral meeting with the Emir of Qatar, Trump stated that the agreement makes it "loud and clear" that Iran will never be permitted to develop or acquire a nuclear weapon.[2][6]

"The only thing that really matters to me is Iran will never have a nuclear weapon," Trump told reporters. He warned that if the Iranian government attempted to purchase or build one, "all hell will rain down on them." The president characterized the new framework as a definitive "wall" against nuclear proliferation, contrasting it sharply with the 2015 Obama-era accord, which he claimed was merely a "road" to a weapon.[2][3][6]

A central and highly scrutinized pillar of the emerging deal is the proposed creation of a $300 billion international investment fund designed to aid in Iran's post-war reconstruction. The Financial Times reported that the Trump administration is prepared to allow the establishment of this massive capital pool, provided Tehran strictly adheres to the final settlement's terms.[1]

The proposed reconstruction fund would rely on private international capital, gated by strict compliance metrics.

The scale of the financial incentives has sparked immediate political blowback in Washington. Trump forcefully pushed back against characterizations that the U.S. government was writing a check to Tehran, taking to Truth Social to label reports of a $300 billion American payout as "Fake News." U.S. officials clarified that the fund would not consist of direct government payments, but rather private capital pooled from European, Asian, and American corporations eager to enter Iran's energy and infrastructure markets once sanctions are lifted.[1][4]

Vice President JD Vance reinforced this distinction, noting that the $300 billion reconstruction fund represents the type of capital Iran could access "so long as they honor their end of the obligation." Any sanctions relief, including the unfreezing of Iranian assets held overseas, would be released in strict phases tied directly to verifiable progress in nuclear compliance and the maintenance of the ceasefire.[1][4][7]

For the Iranian leadership, the investment fund is viewed as essential compensation for the extensive damages sustained during the recent U.S.-led "Operation Mighty Wrath" bombing campaign. Iranian Deputy Foreign Minister Abbas Araghchi confirmed that top negotiator Mohammad Bagher Ghalibaf will attend the signing ceremony in Switzerland, with formal talks on the final nuclear agreement slated to begin immediately after.[5]

A critical immediate priority for global markets is the Strait of Hormuz. The MoU reportedly mandates the reopening of the vital waterway, though the exact timeline remains a point of friction. Washington is demanding an immediate resumption of transit alongside mine clearance operations, while Tehran has sought the authority to levy future transit fees on shipping traffic.[1][4]

Reopening the Strait of Hormuz to international shipping is a central condition of the interim peace agreement.

The diplomatic breakthrough has been met with deep skepticism in Israel. Prime Minister Benjamin Netanyahu's government views the financial relief as a dangerous concession that prioritizes temporary quiet over the permanent elimination of the Iranian threat. Israeli officials have expressed concern that an influx of foreign capital could ultimately embolden Tehran's regional proxy networks, despite the strict nuclear guardrails.[2][3]

As the Friday signing approaches, the focus shifts to the technical implementation of the nuclear rollback. Negotiators have reportedly agreed that the baseline requirement involves the on-site dilution of all highly enriched uranium under the direct supervision of the International Atomic Energy Agency (IAEA), setting the stage for one of the most heavily monitored disarmament processes in modern history.[1][6]

Viewpoints in depth

US Administration's view

The White House views the deal as a definitive block against Iranian nuclear proliferation achieved without taxpayer dollars.

U.S. officials emphasize that the proposed $300 billion fund is a mechanism to leverage private international capital rather than American government funds. By tying phased sanctions relief and corporate investment directly to verifiable IAEA compliance, the administration argues it has created a structure where Iran is heavily incentivized to abandon its nuclear ambitions. President Trump and Vice President Vance have framed this as a far more robust safeguard than previous diplomatic efforts, backed by the credible threat of overwhelming military force if the terms are breached.

Iranian Leadership's view

Tehran sees the agreement as a necessary step to rebuild its war-torn infrastructure and escape crippling economic isolation.

For Iran, the $300 billion investment fund is framed domestically as a form of reconstruction compensation following the extensive damage caused by recent U.S. military operations. Iranian negotiators have prioritized immediate sanctions relief and the unfreezing of overseas assets to stabilize their domestic economy. While agreeing to the on-site dilution of highly enriched uranium, Tehran is also seeking to assert its sovereignty by attempting to negotiate future transit fees for vessels passing through the newly reopened Strait of Hormuz.

Israeli Government's view

Israel views the financial incentives as a dangerous lifeline to a regime that remains an existential threat.

Prime Minister Benjamin Netanyahu and the broader Israeli security establishment are deeply alarmed by the prospect of a $300 billion capital injection into Iran. They argue that even if the funds are technically earmarked for civilian reconstruction, the massive economic relief will inevitably free up domestic resources for Tehran to rearm and fund its network of regional proxy militias. Israeli officials fear the agreement repeats the mistakes of the 2015 JCPOA by prioritizing a temporary cessation of hostilities over the permanent dismantling of Iran's military capabilities.

What we don't know

  • The exact timeline and operational mechanics for clearing mines and reopening the Strait of Hormuz.
  • Which specific European and Asian corporations have committed to the $300 billion investment fund.
  • How the IAEA will physically secure and monitor the on-site dilution of Iran's highly enriched uranium.

Key terms

Memorandum of Understanding (MoU)
A preliminary formal agreement outlining the broad terms of a diplomatic deal before a final, binding treaty is signed.
Highly Enriched Uranium (HEU)
Uranium that has been processed to contain a high percentage of the U-235 isotope, making it capable of being used in nuclear weapons.
Strait of Hormuz
A critical shipping chokepoint between the Persian Gulf and the Gulf of Oman, through which a significant portion of the world's oil supply passes.
IAEA
The International Atomic Energy Agency, the United Nations watchdog responsible for monitoring and verifying civilian nuclear programs.
