G7 backs contentious U.S.–Iran deal as Hormuz opens and critics warn of exposed leverage
G7 leaders have lined up behind a slim U.S.–Iran memorandum that promises to lift sanctions and reopen the Strait of Hormuz, even as key details stay secret and Israeli officials denounce the terms as a dangerous concession. The move could unfreeze Iranian oil, reshape Gulf security and test whether Washington can trade economic pressure for promises on nuclear restraint and regional de‑escalation.
The world’s richest democracies moved to lock in a new Middle East risk calculus on 17 June, backing a U.S.–Iran understanding that could reopen the Strait of Hormuz and dismantle much of Washington’s sanctions architecture in exchange for an end to regional fighting and a pledge from Tehran not to build nuclear weapons. The political bet is that economic relief can buy de‑escalation; the risk is that the United States gives up leverage faster than Iran gives up tools of pressure.
G7 leaders signalled their support for the agreement on Wednesday, reaffirming backing for what they described as a U.S.–Iran deal and indicating readiness to help implement it. A text described as a 14‑point memorandum of understanding has circulated in regional and Western media, presenting the outline of an immediate ceasefire “on all fronts, including Lebanon,” mutual commitments to respect sovereignty, and an Iranian declaration that it will never produce nuclear weapons. In return, the United States is widely reported to have pledged to lift all Iran‑related sanctions, end maritime interdictions widely seen as a de facto blockade, and support the creation of a multibillion‑dollar reconstruction fund for Iran.
Senior U.S. officials are working to lower expectations around the document itself, describing the 1.5‑page memorandum as a vague political framework that does not capture all of the understandings Washington believes it has reached with Tehran. One official cautioned that observers “shouldn’t read too much into the language” and stressed that unwritten back‑channel commitments matter as much as the visible text. Canadian Prime Minister Mark Carney has said he is among the few foreign leaders to have seen the MoU, underlining how tightly Washington has controlled access to the details.
On the ground, the signals are mixed. U.S. interlocutors say that since the MoU was digitally signed on Sunday, Iran’s Islamic Revolutionary Guard Corps has continued to launch drones nightly, with U.S. forces intercepting them. Separate reports claim Iranian drones were fired at commercial ships in the Strait of Hormuz and that three Iranian tankers carrying nearly 5 million barrels of crude have for the first time in months emerged from a U.S. naval blockade as a Hormuz reopening nears. None of these elements has been formally acknowledged by all parties, but taken together they point to a messy, contested transition rather than a clean break from confrontation.
In Israel, senior figures are treating the agreement not as a safety valve but as a threat. Finance Minister Bezalel Smotrich has publicly attacked what he calls "Trump's Iran deal," labelling it "bad" and arguing that Israel should not stay silent. He accuses the understanding of halting Israeli efforts that, in his telling, had severely damaged Iran’s economy, industry and nuclear program. Smotrich also openly rejects any linkage between the MoU and Israel’s military posture in Lebanon, insisting there will be no withdrawal and that the Israel Defense Forces will retain full freedom of action north of the border.
The stakes extend far beyond the diplomatic theatre. For Gulf tanker crews and shipping operators, the difference between a formally "open" Strait of Hormuz and one shadowed by drones and ambiguous rules of engagement is measured in risk premiums and route decisions. Insurers, refiners and crude buyers now have to price the possibility that millions of barrels of Iranian oil could return to market under looser enforcement, reshaping trade flows and pressuring rivals from Russia to Gulf producers at a moment when global energy demand and climate policy are already forcing painful adjustments.
Politically, the MoU is testing long‑standing U.S. narratives about Iran. Republican vice‑presidential nominee JD Vance has framed the goal not as regime change but as destroying Iran’s ability to project power across the region, suggesting that if Tehran "changed its behaviour" in a way comparable to Saudi Arabia’s recent image overhaul, Washington should want Iran "to be a successful country." At the same time, he acknowledges that text publication is being delayed at the request of mediators such as Pakistan and Qatar, citing sensitivities in the Arab and Muslim worlds that Washington is trying to navigate.
Hormuz risk does not need a formal closure to matter; it only takes enough uncertainty for shipowners, insurers and governments to hesitate. That is why a thin, partly secret memorandum between old adversaries is already moving markets and military deployments, even before its clauses are fully implemented or tested.
The next signals to watch are whether Iranian export volumes rise in a sustained way, how quickly Western sanctions enforcement is relaxed in practice, and whether front‑line theatres such as Lebanon and the Red Sea see a measurable drop in fire. Any serious attack on commercial shipping or renewed nuclear brinkmanship would quickly call the deal’s durability into question, while concrete steps to codify the MoU into more detailed agreements could turn a fragile political document into a new architecture for managing U.S.–Iran rivalry.
