Trump's team said the MoU (memorandum of understanding) framework was "approved at the highest level of Iranian leadership". That level is Supreme Leader Mojtaba Khamenei, who has not appeared in public since 8 March and is reachable only by handwritten message in a sealed envelope, carried by courier with a three-to-five-day lag1.
The day before, analysts assessed that the IRGC (Islamic Revolutionary Guard Corps), not Khamenei, holds day-to-day war authority, with no memorandum response recorded from the top. So the approval claim collides with the command structure. A framework cleared "at the highest level" inside the signing window Trump describes would have to pass a decision node that needs days to deliver a single letter, while the corps runs the kinetic war in the meantime.
Iran's wartime command was deliberately decentralised after the February decapitation, devolving launch authority to provincial units and leaving the state with no single ratifying voice the war machine was redesigned to do without. Either someone other than Mojtaba approved the text, or the word "approved" is doing lighter work than it implies. Until the IRGC itself comments, the claim cannot be verified at deal speed.
