Shapiro's central claim is that the MOU is a disaster because it leaves enrichment, ballistic missiles, and support for terrorism unresolved while granting Iran relief. The released text of the memorandum, published by Iran International and reported on by The Guardian, confirms each of these points.
On enrichment, paragraph 8 of the MOU states that Iran "reaffirms that it shall not procure or develop nuclear weapons" and agrees to discuss the "disposition of stockpiled enriched material" through down-blending, but explicitly defers the question of enrichment itself to the final deal. Trump himself acknowledged at the G7 that Iran has rights to enrich uranium for civilian use. Shapiro's claim that there is "no end to enrichment" is accurate as a description of what the MOU actually requires.
On ballistic missiles, the memorandum contains no provision addressing Iran's missile program. The Guardian reports that Trump told reporters Iran "has to have some, because other people have some," and the G7 joint statement noted that a follow-on agreement would be necessary to address missiles. Shapiro's assertion that missiles are not addressed in the deal is borne out by the text.
On terrorism and proxy support, the MOU requires Iran to "restrain its foreign allies including Hezbollah in Lebanon" and includes Lebanon in the ceasefire, but does not dismantle proxy networks or end material support for groups designated as terrorists. Shapiro's framing that there is "no end to the regime's support for terrorism" reflects what the document actually says.
On relief, the MOU grants Iran immediate and substantial concessions: the US commits to lifting its naval blockade within 30 days, issuing waivers for Iranian crude oil exports, making frozen Iranian funds fully available, and developing a $300 billion reconstruction plan. Shapiro's point that "the regime gets relief anyway" is directly supported by paragraphs 4, 6, 10, and 11 of the text.
The question Shapiro raises, "what exactly did the regime give up?," is more nuanced. Iran commits to a 60-day ceasefire, toll-free passage through the Strait of Hormuz for 60 days, down-blending its 440-kilogram stockpile of highly enriched uranium, and negotiations toward a final deal. These are real concessions, but they are largely reversible or temporary, which is the core of Shapiro's critique.
