Key takeaway

Iran's binding commitments are verbal, so neither legislature can review or enforce the deal.

The text of the Islamabad Memorandum of Understanding still had not been published as of Wednesday 17 June. JD Vance, the US Vice President who signed for Washington, promised it "as early as tomorrow" on Tuesday; Wednesday came and went with nothing released ¹. Senate Majority Leader John Thune formally pressed Trump for the document, and Senate Republicans signalled they will not back the deal without seeing it ². Minority Leader Chuck Schumer demanded a Gang of Eight intelligence briefing, the closed session in which the eight senior congressional leaders review classified material.

US officials told CNN the document can stay vague because the binding terms sit outside it: Iran's critical commitments are not written into the signed text at all, and exist as verbal side-deals through the back-channel ³. Vance described the instrument as "approximately a page and a half". An agreement whose binding terms are spoken rather than signed cannot be enforced by either legislature, which is precisely why the IRGC and Mojtaba Khamenei have left it unsigned at their end .

The zero-transit reality in the strait and the empty insurance line that pinned more than five hundred ships in place both turn on terms no document records. A blank text means either party can later deny a commitment with no paper to contradict it, and that is the structural weakness the Majlis revolt and the Senate's refusal to endorse are both probing from opposite sides.

Deep Analysis

In plain English

The Islamabad Memorandum's text had not been released by 17 June. Senate Majority Leader John Thune formally asked to see it; Republicans said they would not support the deal without reading it first. US officials told CNN that Iran's most important commitments are not written into the document at all: they exist as spoken back-channel assurances. A verbal commitment cannot be enforced by courts, legislatures, or international organisations. If the US or Iran later disputes what was promised, there is no signed text to appeal to. That is why both Thune and Minority Leader Schumer pushed hard for the document: without it, the Senate has no leverage to hold either side to account.

Deep Analysis

Root Causes

The MOU's verbal-commitments structure has one direct cause: the two sides could not agree on written text for Iran's nuclear obligations without triggering immediate domestic political crises in both Tehran and Washington. Anything Iran commits to in writing on enrichment becomes a Majlis vote in Iran and a Senate ratification battle in the US.

The page-and-a-half length reflects a deliberate omission of substance, not an economy of drafting. A ceasefire instrument that defers enrichment, stockpile accounting, ballistic missiles, and IAEA re-entry dates cannot be page-and-a-half long unless those subjects were removed from the text entirely.

What could happen next?

Risk
Verbal Iran commitments on nuclear enrichment and IAEA access cannot be enforced by the US Senate, international courts, or the IAEA itself; the 60-day talks open with no verified baseline.
Precedent
A sole executive agreement with unpublished operative terms sets a precedent that US Iran policy can proceed without any congressional visibility, strengthening executive discretion but reducing institutional durability.

Source Landscape

This story draws on centre-left-leaning sources from United States and Israel

United States

Israel

Primary parallel: The 1981 Algiers Accords ended the 444-day US hostage crisis. Algeria brokered the agreement; Iran signed; the US acknowledged rather than signed it, because direct signature was politically impossible for both governments's domestic audiences.

A separate set of confidential diplomatic undertakings carried the binding financial terms. The Islamabad MoU shares the same architecture: a short public instrument whose real commitments sit in a back-channel the Majlis and Senate cannot read.

Counter-parallel: The 2015 Joint Comprehensive Plan of Action ran to 159 pages with five technical annexes. Congressional opposition to its sole-executive-agreement status was fierce, but the published text gave Congress the minimum transparency that allowed treaty-adjacent oversight. The unpublished Islamabad MoU denies even that baseline.

Consensus view: A sole executive agreement, unlike a treaty, carries no Senate ratification requirement but also carries no domestic legal force unless backed by statute. The Islamabad MoU, as described, appears to be an executive agreement of the weakest sub-type: a presidential communication unsupported by either statutory authority or Senate consent. If Iran's critical commitments are verbal, they exist only at the pleasure of the parties' current leadership.

Counter-view: Verbal understandings have preceded formal US-Iran deconfliction before. The 1981 Algiers Accords ended the 444-day hostage crisis through Algerian intermediaries rather than direct US-Iran contact, with a public instrument backed by confidential diplomatic exchanges carrying the operative financial terms. The back-channel architecture is not a weakness but a deliberate design for a political system where the Supreme Leader cannot openly sign with Washington.

Key tension: Whether the verbal commitments can survive a US or Iranian leadership change in the 60-day window, given that neither Congress nor the Majlis has seen or ratified the operative terms.

Led to

Iran deal published, Treasury record blank

The published MOU text answers the Senate demand for the document that was withheld on 17 June; the blank OFAC record confirms the gap.

Different Perspectives

Shipping and insurance industry

UKMTO counted about 20 US-facilitated Hormuz transits a day to 11 September against only 6 visible on AIS, with traffic still around 90% below the 138-a-day pre-war baseline. War-risk underwriters cannot price hulls they cannot see, or resolve whether the tanker El Gaia hit a mine, as Iran claims, or a missile and drone, as CENTCOM says.

European refiners

European refiners, including Poland's Orlen, absorbed a roughly $26 gap between Dated Brent at $130.80 on 15 September and ICE Brent futures settling at $103.87 on 18 September, a spread that widened from $13.45 on 9 September rather than newly opening. Their futures hedges no longer cover what they now pay for physical barrels.

Saudi Arabia

Saudi Aramco zeroed European term customers' October allocations and rerouted roughly 60 million barrels to Asia through Ras Tanura and Sohar, using Red Sea and Gulf terminal capacity built years ago to cut Hormuz exposure. Riyadh reallocated existing supply rather than negotiating a shortfall with Europe.

Qatar

Qatar's energy minister Saad al-Kaabi told Bloomberg at the Qatar Economic Forum on 20 September that Bessent's two-year Hormuz-obsolescence forecast is wrong, and that Doha has deliberately built no bypass pipeline. Qatar's gas exports run through one waterway by choice, not oversight.

Iran (foreign ministry and Majlis)

Iran's foreign ministry and 130 Majlis deputies moved toward NPT withdrawal this week, with lawmaker Hossein-Ali Haji Deligani filing a triple-urgency bill on 20 September that Speaker Qalibaf has not yet scheduled. Tehran treats treaty membership as leverage still on the table, not yet spent.

Russia and China

Moscow and Beijing vetoed the Panel of Experts' renewal, maintaining Resolution 2231 lapsed in October 2025 and the 2025 snapback was never validly triggered, so the sanctions architecture the Panel enforces has no current legal standing. Both governments frame the veto as upholding law, not shielding Tehran.
