US aircraft struck missile and drone sites on Iran's Qeshm Island on 26 June, the first American attack on Iranian soil since Trump signed the Islamabad memorandum. It answered an IRGC drone strike on a Singapore-flagged container ship; a second vessel was hit two days later. Brent crude fell through all of it to $71.99. A signed US-Israel-Lebanon framework collapsed within hours, rejected by Hezbollah.
CENTCOM has become the sole enforcement mechanism for every paper commitment the Islamabad MOU produced.
CENTCOM bombed missile and drone storage on Iran's Qeshm Island on 26 June, the first US strike on Iranian soil since Trump signed the Islamabad memorandum ten days earlier.
United StatesQatarUS aircraft struck Iranian military sites on Qeshm Island and near Sirik on 26 June. It was the first US attack on Iranian soil since the Islamabad deal, signed ten days earlier.
US forces ran the raid under existing authority, with no new presidential directive. The 26 June Qeshm strike, not the Islamabad text, now enforces the ceasefire terms.
An IRGC drone hit the Singapore-flagged container ship Ever Lovely on 25 June, 7.5 nautical miles off Oman, inside the very lane the IMO had opened for safe passage.
QatarAn Iranian drone struck the Ever Lovely in the Hormuz safe corridor on 25 June. US forces downed three of four drones; the fourth hit the ship; all crew escaped injury.
The Guards had declared the corridor unacceptable that same morning . Five South Korean vessels crossed unmolested the same day, showing they singled out the Taiwanese-operated ship.
The IRGC's Persian Gulf Strait Authority suspended the IMO evacuation corridor within hours of the Ever Lovely strike, trapping roughly 11,000 seafarers; a second ship, the tanker Kiku, was hit two days later.
Iran's maritime arm suspended the Hormuz evacuation corridor within hours of the Ever Lovely attack on 25 June. Around 11,000 seafarers lost their only sanctioned exit. The tanker Kiku was struck on 27 June.
Two ships struck in 48 hours means no captain will cross unescorted. The trapped seafarers now serve as diplomatic leverage rather than a crisis to resolve.
The US, Israel and Lebanon signed a framework on 27 June tying Israeli withdrawal to Hezbollah's disarmament; Hezbollah's Naim Qassem rejected it as null and humiliating within hours.
Qatar×2United StatesThe US, Israel and Lebanon signed a Washington framework on 27 June linking any Israeli withdrawal to Hezbollah handing over its weapons. Hezbollah's leader Naim Qassem rejected it within hours as null and humiliating.
The rejection closes Iran's nuclear gate. Tehran has made a Lebanon settlement a precondition for nuclear talks, and Qassem's veto keeps that condition unmet.
Israel struck Nabatieh, Deir Siryan and Taybeh on 27 and 28 June after a Hezbollah gunman killed Golani captain David Hazutt, 21, calibrating its answer to targeted raids rather than wider war.
QatarIsrael struck Nabatieh on 27 June and two more south Lebanon villages on 28 June in targeted raids. A Golani Brigade captain, David Hazutt, 21, was killed by a Hezbollah gunman on 28 June.
Israel calibrated the raids rather than escalating strategically, keeping the Lebanon framework signed the previous day technically alive and avoiding a wider confrontation.
The Institute for Science and International Security read 265 to 287 kg of highly enriched uranium in Esfahan's backfilled tunnels from satellite imagery, against the 440.9 kg the memorandum commits Iran to destroy under inspectors who cannot enter the country.
QatarIran has locked out nuclear inspectors for more than 100 days. Only satellite imagery can read its stockpile, estimated at around 460 kg of highly enriched uranium.
Iran's deputy foreign minister ruled out inspection access before a full deal and sanctions relief. That blocks verification of the 460 kg disarmament commitment before the 21 August deadline.
The Strait of Hormuz moved roughly 20 million barrels of oil in 24 hours on 25 June, a single-day crisis record confirmed by US Energy Secretary Chris Wright, hours before the IRGC struck inside the corridor.
Hormuz moved roughly 20 million barrels of oil on 25 June, a single-day record for the crisis period that matched the pre-crisis daily norm. Energy Secretary Chris Wright confirmed the figure.
Iran's Revolutionary Guards struck the Ever Lovely inside the corridor the same day, choosing to enforce their authority at peak throughput rather than at a quiet moment.
Brent crude settled at $71.99 on 26 June, down from $76.14 on 24 June, falling steadily through both the IRGC drone strike and the US bombing of Iranian soil.
United StatesBrent Crude settled at $71.99 on 26 June, a 5.4 per cent fall in two sessions. It declined through both the Iranian drone attack and the US strike on Qeshm Island.
Markets priced the record Hormuz throughput of 20 million barrels, not the kinetic exchange. The war premium that drove Brent above $100 at the peak has not returned.
The conflict is at contained escalation: US struck Iranian soil, IRGC struck inside an IMO corridor, a second vessel was hit, all within the existing deterrence ceiling. The specific mechanism that tips it upward is IRGC shift from selective vessel targeting to corridor-wide enforcement, at which point Brent reverses from $71.99 toward the $100+ war-premium level with no diplomatic instrument available to absorb the move. The reverse mechanism, de-escalation, requires Gharibabadi's inspection preconditions to be dropped before 21 August; the probability of that happening without a political concession of equivalent weight is low given Vahidi's control of the negotiating track since 22 April.
