JD Vance and Iranian Parliament speaker Mohammad Bagher Ghalibaf executed a digital signature on Monday 15 June, formally naming the document the Islamabad Memorandum of Understanding. 1 It is the first Iran instrument either side has signed in 108 days of war. The two had been publicly named as signatories the day before , so the signature itself was expected; what followed was not.
Twenty-four hours later the White House Presidential Actions index listed a cyber-security memo, a Flag Day proclamation and a batch of nominations, and nothing on Iran. 2 OFAC, the US Treasury's sanctions-enforcement office, had logged no new Iran designation, and the Federal Register, the government's daily journal of executive orders and rules, carried no Iran entry either. Trump had declared the deal done on Truth Social the day before the signing ; the digital signature is the act that declaration described.
US law does not treat a Memorandum of Understanding as self-executing. Sanctions relief runs through OFAC general licences and, for anything statutory, through waivers the President must sign and publish. None of that machinery has moved, which leaves the instrument doing far less than the announcement that preceded it. The document runs to roughly a page and a half, stays secret until a formal ceremony in Geneva on Friday 19 June, and parks the nuclear question for 60 days while leaving sanctions, missiles and Iran's regional proxies out of the text entirely.
