Iranian negotiators have secured revisions to a US memorandum of understanding and obtained written guarantees covering Lebanon, according to sources familiar with the talks. The interim agreement is intended to pause a cycle of escalation, but its temporary nature leaves open deep disagreements over nuclear compliance and regional influence.
How the memorandum was rewritten
The original US draft, presented earlier this month, was met with objections from Tehran over language that Iran considered too restrictive on its nuclear enrichment activities. In the final version, several paragraphs were replaced with more ambiguous wording, and a clause linking the deal to progress in Vienna negotiations was removed. Iranian officials say the changes remove what they called "unilateral constraints" not required under the Nuclear Non-Proliferation Treaty.
US officials have not publicly confirmed the alterations, but internal memos reviewed by GFdaily confirm at least three passages were softened. One section that originally required Iran to grant inspectors access to military sites now reads that access will be "consistent with agreed frameworks". Another reference to sanctions snapback was deleted entirely.
What the Lebanon guarantees cover
A separate side letter, signed by both parties, commits the US to support Lebanon's territorial integrity and to refrain from pressing sanctions on Lebanese banks that process Iranian humanitarian transactions. The guarantees also include a pledge to work with the International Monetary Fund on a debt restructuring plan for Lebanon, which Iranian representatives pushed for during the talks.
For Beirut, the guarantee is a rare diplomatic win. The country has been without a functioning government for months, and its currency has lost more than 90 percent of its value since 2019. The memorandum does not detail enforcement mechanisms, leaving implementation largely to trust.
Why the deal is only temporary
The memorandum is explicitly interim, with a renewable 60-day term. That means neither side has resolved the core dispute: Iran's enrichment to 60 percent purity, which is weeks away from weapons-grade, and US demands that Iran halt all enrichment above 3.67 percent. The text mentions "continued technical talks" but sets no deadlines.
Compliance hurdles also remain. Both sides must verify each other's actions through a joint commission that has yet to be formed. Past experience with similar interim arrangements shows that verification can stall for months. If either side accuses the other of cheating, the memorandum could collapse quickly, pulling in Lebanon as a collateral casualty.
The period ahead will test whether the revised language and the Lebanon guarantees are enough to prevent a new crisis. With enrichment levels already close to the threshold for a nuclear device, any breakdown in the interim deal could reignite military tensions across the region. The next 60 days will show whether the memorandum actually stops the clock or simply postpones the alarm.
