Islamabad Without a Deal
Published 4 October 2026
The first week after the April ceasefire contained a face-to-face negotiation, a naval blockade, a Hormuz reopening that did not last and an extension, which is a lot of diplomacy for a truce that was supposed to last two weeks.
Sunday 12 April
US and Iranian delegations met face to face in Islamabad. The talks ended without agreement, per the AP timeline. Sunday is worth stating because the next sequence is tightly packed.
Monday 13 April: the blockade
The following day, President Trump said a US blockade of Iranian ports had begun. It is important to keep two things apart here: Iran's restrictions on passage through Hormuz, and the US blockade of Iran's own ports. They are two different pressure tactics aimed at the same outcome, and they got mixed in many headlines. The blockade is what the June memorandum later promised to unwind over 30 days.
The two Lebanon tracks
Lebanon and Israel held their first direct diplomatic talks in decades in Washington on 14 April. Two days later a separate US-backed cessation between Israel and Lebanon began on 16 April at 21:00 GMT, for ten days. Reuters explained the State Department-published terms on 17 April, in what the deal was and whether it would hold. Lebanon would take meaningful steps to stop attacks by Hezbollah and other groups. Lebanese state forces would have exclusive responsibility for sovereignty and national defence. Israel preserved the right to take necessary self-defence measures against planned, imminent or ongoing attacks. There was no requirement for immediate Israeli withdrawal; Israeli defence officials said troops stayed up to about 10 kilometres inside southern Lebanon. And the text did not explicitly require Hezbollah to disarm, though broader political demands said so. Hezbollah stopped firing but did not publicly endorse all the terms.
Those terms explain why "ceasefire" did not mean Israeli withdrawal or a ban on every later Israeli strike. They do not settle the legality of any particular strike. Nobody who reads the text will find a clause that makes an Israeli strike an automatic breach.
Friday 17 April, Tuesday 21 April
On 17 April Iran said it had reopened Hormuz. The reopening did not last, per the AP timeline. Four days later, on Tuesday 21 April, Trump extended the ceasefire indefinitely. An indefinite extension is a curious object. It removes the cliff edge of a deadline and with it the pressure to settle.
What it left on the table
By the end of that week four things coexisted: a ceasefire without an end date, a US blockade of Iranian ports, an Iranian grip on Hormuz that was neither fully closed nor fully open, and a Lebanese track with its own terms and its own arguments. Peace needed all four to change at once. None of them did, and the next chapter shows how each side explained that to its own lawyers.
The oil price over the same days fell from its early April peak. The EIA spot close on 17 April, the day Iran said the strait reopened, was $98.63, the lowest close of that month in the series. The futures series also made its April low, $86.09, on that day. A price that drops about $40 in ten days is a price that believed, for a moment, that it was over.
