Key takeaway

Lebanon carries the human cost of a ceasefire that does not cover it.

As the Islamabad talks concluded on 12 April, IDF (Israel Defense Forces) strikes killed 18 people in southern Lebanon, 13 of them in the village of Tefayta. The strikes continued a pattern that began on ceasefire day itself: on 7 April, hours after the Iran ceasefire was announced, Israel struck more than 100 targets across Lebanon, killing at least 303 people and wounding over 1,150.

Benjamin Netanyahu declared the ceasefire "does not bind Israel in Lebanon." Trump supported that position. The 98th Division deployed into southern Lebanon during the ceasefire window, joining four divisions already operating there: the 36th, 91st, 146th, and 162nd . Five IDF divisions are now active in a country that is not formally part of any ceasefire agreement.

Iran formally accused the US of ceasefire violations and warned that its allies are "an inseparable part" of the ceasefire, with violations carrying "explicit costs and strong responses." Hezbollah had fired a missile at Tel Aviv days earlier, triggering air-raid sirens across three Israeli cities; it was intercepted . Iran listed Lebanon as a precondition at Islamabad. It was not resolved.

Lebanon has no seat at the negotiations, no ceasefire of its own, and no voice in the terms. It is the active front in a war whose ceasefire explicitly excludes it. Beirut bears the cost of strikes that Iran cites as violations. For Lebanese civilians, the ceasefire is something that happened to other people.

Deep Analysis

In plain English

The ceasefire announced on 7 April was between the US and Iran. It said nothing about Lebanon, where Israeli forces have been fighting Hezbollah, an Iranian-backed armed group, for months. While US and Iranian diplomats were talking in Islamabad, Israeli strikes killed 18 people in southern Lebanon. Iran had told the talks: Lebanon must be part of any deal. The US and Israel said Lebanon is a separate issue. This matters because Hezbollah is Iran's most important regional partner. For Iran to accept a deal that leaves Lebanon out would be politically very difficult at home, it would look like Iran abandoned an ally. So what happens in Lebanon has a direct effect on whether a nuclear or Hormuz deal is possible.

Deep Analysis

Root Causes

Netanyahu's declaration that the ceasefire 'does not bind Israel in Lebanon' reflects the Israeli government's longstanding position that Lebanese operations are separate from any US-Iran framework. The US accepted this carve-out when it agreed the ceasefire terms, which means the ceasefire was structurally incomplete from day one.

The five IDF divisions currently in southern Lebanon represent a force posture that has no parallel since the 2006 war; the 98th Division's deployment alongside the 36th, 91st, 146th, and 162nd represents the largest Israeli ground commitment in Lebanon in two decades. This is not an incidental border operation, it is a sustained campaign.

What could happen next?

Risk
Iran's formal ceasefire violation accusation over Lebanon operations provides Tehran with a legally-framed pretext to abrogate the ceasefire at any point before 22 April, particularly if IDF operations intensify or a high-profile Hezbollah target is struck.
Consequence
Lebanon has no seat at the Islamabad talks and no ceasefire of its own; even a complete Iran-US nuclear deal would leave the Lebanese conflict unresolved and Hezbollah under active IDF pressure, creating a persistent flashpoint.

Qatar×2

Primary parallel: The 2006 Lebanon-Israel war ended with UN Security Council Resolution 1701, which established a ceasefire based on Hezbollah disarmament commitments that were never fulfilled. The current Lebanese front reflects the same structural failure: Israel accepts ceasefires with Hezbollah as temporary pauses rather than permanent settlements.

Counter-parallel: The 1993 Oslo Accords separated the Palestinian track from the Lebanese track, allowing progress on one without resolving the other. The US is attempting the same disaggregation, handling Iran bilaterally while treating Lebanon as a separate Israeli security matter. Iran is explicitly rejecting that disaggregation.

Consensus view: Al Jazeera's analysis and the Carnegie Endowment's assessment both identify Lebanon as the wildcard most likely to collapse the Iran ceasefire entirely: Iran cannot publicly accept a deal that leaves its primary proxy under active military attack, and Israel has no operational incentive to pause Lebanon operations while Iranian nuclear talks are ongoing.

Counter-view: The IDF's continued operations may reflect a deliberate Israeli strategy to maintain pressure during the ceasefire window specifically, calculating that Iran will not abrogate the ceasefire over Lebanon if the nuclear and Hormuz stakes are high enough.

Key tension: Iran's formal accusation that the US is violating the ceasefire by permitting Israeli Lebanon operations creates a legal pretext for Tehran to abrogate the agreement at a time of its choosing, giving Tehran an off-ramp that does not require returning to war.

Different Perspectives

Lloyd's of London

The Joint War Committee left Hormuz war-risk premiums at $10-14 million per voyage on 25 May, declining to move on Brent's 5% fall. The JWC's protocol requires a UN Security Council resolution or bilateral government certification letter before de-listing, and neither has arrived: a verbal understanding does not satisfy the formal condition the reinsurance market's treaty terms require.

Gulf Arab producers

Saudi Arabia and UAE depend on Hormuz for their own crude exports; Aramco CEO Nasser has warned no oil market recovery arrives until 2027 if the blockade continues past mid-June. Monday's $98.96 Brent settlement shortens nothing for Gulf producers without a signed instrument and a Pentagon mine-clearance timeline that runs up to six months post-ceasefire.

Qatar

Qatar holds $12bn of frozen Iranian assets at the centre of the sequencing dispute but cannot release them without explicit US Treasury authorisation, given the original freeze was a US instrument. As the asset-holding state, Qatar's leverage is real but passive: it is the escrow holder, not the decision-maker, and any resolution requires US Treasury sign-off that Trump has withheld.

Pakistan

With both Prime Minister Sharif and army chief Munir simultaneously in Beijing on 25 May, Pakistan has for the first time consolidated its civilian and military mediation tracks under China's roof. Munir's direct Tehran-to-Beijing flight signals that the security and financial threads of the sequencing problem are now being worked in parallel rather than sequentially.

China

Beijing hosted Pakistan's principal mediators and Iran's China envoy Ghalibaf simultaneously on 25 May while its banking regulator capped new state-bank lending to five sanctioned refiners. China is simultaneously the most credible third-party underwriter of the $12bn sequencing and the state whose institutions face live OFAC secondary-sanctions exposure if the deadlock persists through GL V's expiry.

United States

Trump posted on 24 May that the blockade holds until a deal is certified and signed, ruling out the informal MOU structure both sides had been building. The 'certified, and signed' condition is the first operational bar Trump has attached in 87 days, but it arrived without an executive instrument, maintaining the gap between posted ultimatum and signed US policy.
