Inside the U.S.-Iran Memorandum of Understanding: What It Covers, What It Defers, and Why Israel Objects

What the memorandum of understanding contains

By late May and early June 2026, negotiators from both sides converged on a one-page MoU. Its key provisions, as reported across multiple outlets, include:

• Strait of Hormuz: The waterway would reopen immediately upon signing, with Trump declaring it would be "permanently toll free" . The U.S. blockade in the Gulf of Oman would also be lifted .
• Ceasefire extension: The existing ceasefire would be extended by 60 days, with the possibility of mutual renewal .
• Nuclear issues deferred: Negotiations on the most contentious subjects — full limits on Iran's nuclear program and the final fate of its enriched uranium stockpiles — were postponed to follow-on talks . Israel has sharply criticized this as leaving critical issues unresolved .
• Oil sales and sanctions relief: Iran would be permitted to sell oil freely during the 60-day window, and Washington would release some frozen Iranian funds .

It is critical to emphasize that this was not a final peace agreement. The MoU is an initial framework setting a 60-day period during which further talks are expected to address comprehensive terms .

Trump’s conditions on enriched uranium and the threat of renewed strikes

While the MoU deferred final nuclear decisions, Trump laid out maximalist public demands for any permanent settlement. He insisted that Iran "must agree" to permanently forgo nuclear weapons . He stated that Iran would relinquish its stockpile of highly enriched uranium and that the U.S. would retrieve and destroy nuclear waste once the situation stabilized .

However, reporting indicates that the MoU itself only includes a moratorium on further enrichment during the 60-day window, with the actual disposition of existing stockpiles left to later negotiations . Axios reported that Trump privately requested edits to the MoU seeking "more specifics about how the U.S. gets the material and the timing" for enriched uranium — terms Iran has categorically refused to surrender .

Trump also repeatedly warned that if no acceptable deal was reached, he was prepared to "complete the task" militarily . He said he was about to make a "final determination" and would not accept a deal that left him unsatisfied .

The Trump-Netanyahu rift

The emerging deal caused a sharp and public rift between Trump and Netanyahu. The Israeli leadership found itself excluded from the negotiation process and confronted with an agreement it viewed as deeply flawed .

Leading Israeli newspaper Yediot Aharonot headlined its reaction in two words: "Bad Deal" . A senior Israeli official told U.S. News, "The preliminary agreement is dreadful for Israel" . From Israel’s perspective, the memorandum postpones negotiations on issues Israel considers existential — nuclear ambitions and missile development — while still offering economic relief to a regime Netanyahu had aimed to weaken .

Trump pushed back aggressively. He openly blamed Netanyahu for delays, accusing Israeli airstrikes on Beirut of undermining the peace process and potentially postponing the MoU’s signing . He argued that despite Netanyahu's objections, he had "saved Israel from nuclear obliteration" . In one of the most striking reported exchanges, Trump warned Netanyahu that if Israel continued attacks jeopardizing the deal, "You'll be on your own" .

Privately, Netanyahu and other Israeli leaders remained cautious about publicly attacking Trump directly, yet harbored significant skepticism . Domestically, the deal became a clear political liability for Netanyahu, who had staked his political future on his relationship with Trump but now faced a population outraged over an agreement that leaves the Islamic Republic intact with sanctions relief on the horizon .

The 60-day clock on the MoU now defines the immediate diplomatic landscape, with the hardest questions — What happens to Iran’s enriched uranium? What nuclear capability will Iran permanently retain? — kicked down the road. The tension between Washington’s deal-making impulse and Jerusalem’s security fears remains, for now, unresolved.
