The Ceasefire Staircase

On June 13, the United States and Iran signed a 14-point memorandum of understanding. It included sanctions lifting, mine clearance in the Persian Gulf, and the removal of the US naval blockade ^[1]. On July 31, seven weeks later, the entire American position had shrunk to a single precondition: Iran must first accept a ceasefire before talks can even begin ^[2]. Iran rejected the demand the next day, vowing to use "all available means" against what it called continued US violations ^[3]. It is a staircase, and each step down followed the same observed pattern. The first agreement was formalized on June 23, when Treasury issued a 60-day general license allowing Iranian oil sales — a reversible lever, not a permanent concession ^[4]. Within a week, Iran's Parliament Speaker Mohammad Bagher Ghalibaf codified the terms under which the deal would hold.

We consider the events that are taking place in the Persian Gulf these nights to be a violation of the understanding to end the war, and we will definitely react to it, and naturally, the other side will react as well. — Mohammad-Bagher Ghalibaf

The doctrine was explicit: Iran would implement its commitments only as long as the other side implemented its own. It was a tripwire, not a foundation. The tripwire snapped almost immediately. By June 30, Iran was warning Washington of alleged ceasefire breaches in the Persian Gulf ^[5]. On July 12, the ceasefire unofficially collapsed after the IRGC attacked commercial vessels in the Strait of Hormuz — the M/V GFS Galaxy and two UAE tankers. Trump reinstated the naval blockade the same day and US Central Command began seven consecutive nights of strikes on Iranian targets ^[6]. By July 16, the war had formally resumed. The pattern was already visible: agreement, breach, retaliation, resumption. But what happened next revealed the deeper dynamic. On July 25, Trump paused the 13-day bombing campaign after advisers warned the military was depleting its arsenal and running out of targets. He declared he was pursuing diplomacy. Yet during this pause, the US naval blockade of Iranian ports continued uninterrupted, while Iranian drones struck Erbil, the US Consulate, and the Khor Mor gas field in Iraq and Jordan on July 27 and 28. Iran also maintained its restrictions on the Strait of Hormuz — daily transits had dropped from roughly 45 vessels to about 13 — turning back ships that did not use its own designated corridor. Neither side's operations actually stop during a ceasefire. Each side's non-implementation gives the other a pretext to resume. And each resumption produces a less ambitious next agreement, because the prior terms were never tested. By July 31, Trump's position had contracted to a demand he framed in absolute terms.

It’s our turn, and we’ll see if we get there with an agreement at some point. But we’re going to hit them very hard. — Donald Trump

The demand that Iran accept a ceasefire before talks was, in effect, a demand that Iran surrender the one leverage it retains — the ability to impose costs. Iran's Foreign Ministry responded on August 2 by accusing the US of violating the June 18 Pakistan-mediated MOU and vowing "full force" in response ^[3]. Beneath the diplomatic cycle, both sides are spending down strategic reserves at rates neither can sustain indefinitely — and neither has found the threshold where erosion produces capitulation. On the American side, Patriot interceptor inventories have dropped roughly 65 percent, from more than 2,300 to between 759 and 827. THAAD interceptors are down 38 percent. Precision Strike Missiles are down 45 percent. The Pentagon has requested $67 billion in supplemental funding and awarded Lockheed Martin a $58.6 billion contract for replenishment. US European Command has warned the Pentagon it lacks sufficient naval forces to protect Israel from Iranian and Houthi missiles, and that without more destroyers it may be forced to prioritize defending the US homeland over Israeli territory ^[7]. Trump's public position is denial.

We have far more munitions than anyone in the world, and far more than we need — Donald Trump

On the Iranian side, the rial has lost 43.7 percent of its value this year, trading at 1.94 million to the dollar. Inflation is running at 88.6 percent, the highest since the Second World War. The government estimates $300 billion in wartime damages ^[8]. President Pezeshkian made the stakes explicit on July 21.

The reality is that today the Islamic Republic of Iran is engaged in a full-scale war. — Masoud Pezeshkian

Both sides are bleeding. Neither is breaking. The counter-evidence is real. Iran is executing protesters — Abolfazl Sepahi Badjani and Amirhossein Safari Hosseinabadi were hanged on July 28 and 29, part of more than two dozen executions since January protests began, with 1,500 death row prisoners now on hunger strike ^[9][10]. The regime has imposed a three-month internet shutdown and faces infrastructure collapse ^[11]. The US State Department alleges Tehran is using the war to justify domestic suppression. On the American side, the Pentagon is weighing a permanent troop reduction in Kuwait after Iranian strikes hit the international airport, port facilities, desalination plants, and energy infrastructure. The Republican Party is fractured, the House passed a war powers resolution opposing the war, and right-wing media has shifted from maximalist support to doubt about costs. These are real costs. But cost is not the same as capitulation. The question is whether either side has a stopping condition — a threshold of pain at which it would accept terms the other side would offer. The evidence so far suggests neither does. And each pause rearms both sides. Satellite imagery shows Iran rapidly rebuilt missile bases at Kangavar, Dezful, and Kermanshah, and a shipyard at Bandar Anzali, despite 11 consecutive nights of US strikes. Israeli officials privately admitted many strikes only collapsed tunnel entrances, leaving stored weapons intact. Iran has also purchased 300 to 400 Chinese shoulder-fired air defense launchers, at a cost of $60 to $70 million, to replace lost capacity. The US, meanwhile, is seeking $67 billion to restock its own depleted inventories. The cycle has no internal mechanism that produces either surrender or a settlement. Each iteration produces a worse agreement on a thinner foundation — from a 14-point framework with sanctions relief to a single precondition that was rejected within 24 hours. The trajectory continues downward, and neither side has shown where it would stop.
