The United States has refused to share the text of a pending memorandum of understanding with Iran, leaving Israel in the dark about the contents of a deal expected to be signed in Switzerland on Friday. The rebuff, first reported by Israel’s Channel 12 and confirmed by multiple international outlets, comes despite intense Israeli lobbying for details of an agreement that could fundamentally alter the strategic balance in the Middle East. According to sources familiar with the matter, Washington declined a formal Israeli request to view the document, which is believed to contain 14 clauses covering the cessation of hostilities, the withdrawal of Israeli forces from southern Lebanon, the release of frozen Iranian assets, and the reopening of the Strait of Hormuz.

Viewed from Tehran, the memorandum represents a diplomatic breakthrough mediated by Pakistan that ends more than three months of military confrontation. Iranian media have framed the deal as a vindication of the country’s resilience, though official details remain sparse. The agreement reportedly establishes a general framework for comprehensive negotiations on Iran’s nuclear programme, with both sides aiming to reach final understandings within 60 days of signing. In Washington, the White House has offered only cryptic signals: President Donald Trump told reporters he would read the document “word for word” at a future press conference, but stopped short of disclosing when that might occur or whether allies would be briefed beforehand.

Israeli officials, viewing the developments from Jerusalem, have reacted with a mixture of alarm and defiance. The cabinet has declared that any agreement between Washington and Tehran is not binding on Israel, particularly clauses that would require the withdrawal of the Israel Defense Forces from southern Lebanon. Analysts in London note that this posture risks opening a rift between Israel and its most critical ally at a moment when the broader architecture of Western deterrence against Iran is in flux. The reported inclusion of sanctions relief—potentially unlocking up to $24 billion in frozen Iranian funds—has further stoked Israeli fears that Tehran will gain the financial means to expand its regional proxy networks.

The memorandum, which Iranian parliamentary speaker Mohammad Baqer Ghalibaf has already signed alongside Trump and Vice President JD Vance, according to Russian media, is distinct from the final accord expected on Friday. That signing ceremony in Switzerland will involve the formal exchange of the 14-clause text, which remains closely held. The lack of transparency has fuelled speculation in Israeli political circles that the deal may tacitly accept a continued Iranian nuclear enrichment capability, a red line for successive Israeli governments. Analysts in Gulf capitals are watching closely, concerned that any US-Iran détente could recalibrate long-standing security guarantees extended to Arab partners.

Looking ahead, the memorandum is designed as a stepping stone to broader nuclear negotiations, but its immediate impact will be measured in the stability of the Lebanon-Israel border and the Strait of Hormuz. Should the deal hold, it could de-escalate a conflict that has drawn in proxies from Yemen to Syria. Yet the exclusion of Israel from the pre-signing consultations injects a note of uncertainty. As one Israeli source told the Jerusalem Post, the lack of transparency raises “serious questions” about the durability of any ceasefire. With the signing ceremony imminent, the international community is left parsing fragmentary leaks and official silences, waiting to see whether the document will deliver a sustainable peace or merely a pause in hostilities.
