Vance-Iran Talks Begin Under Shadow of Lebanon Strikes, Strait Closure
Historic Islamabad negotiations face immediate collapse risk as Israeli airstrikes kill 200+ civilians hours after ceasefire, prompting Tehran to re-close Hormuz and question US commitment.
Vice President JD Vance opened the first direct US-Iran bilateral negotiations since 1979 in Islamabad on Saturday, but the talks face immediate collapse after Israeli strikes in Lebanon killed more than 200 civilians within hours of the ceasefire announcement, prompting Iran to partially re-close the Strait of Hormuz.
The April 11 meeting between Vance’s delegation and Iranian Parliament Speaker Mohammad Bagher Ghalibaf represents the highest-level engagement between Washington and Tehran in 47 years, according to Al Jazeera. Vance leads a team that includes Trump envoy Steve Witkoff and presidential advisor Jared Kushner, while Iran’s Foreign Minister Abbas Araghchi accompanies Ghalibaf. Yet the breakthrough arrives poisoned: Israeli airstrikes on April 8 killed between 200 and 357 civilians in Lebanon in what Lebanese officials described as the largest coordinated wave of strikes since the war began, per Al Jazeera and Lebanese Ministry of Health reports.
The US-Iran conflict erupted February 28, 2026, after failed Nuclear Negotiations. A 12-day kinetic phase ended with a Pakistan-mediated ceasefire on April 7-8, when President Trump called Iran’s 10-point proposal a ‘workable basis.’ Iran’s framework includes non-aggression commitments, controlled Strait of Hormuz passage coordinated with Iranian forces, acceptance of enrichment rights, and lifting of all primary and secondary sanctions.
Ghalibaf stated three of ten ceasefire conditions had been violated by April 9: no ceasefire extension to Lebanon, alleged US drone incursions into Iranian airspace, and Washington’s refusal to accept Iranian enrichment rights, according to Axios. Iran responded by re-closing the Strait of Hormuz on April 9, requiring all tanker traffic to coordinate with Iranian armed forces and accept ‘technical limitations.’ The strait handles roughly 20% of global oil flows.
Energy Markets Whipsaw on Ceasefire Fragility
Brent crude traded at $96.66 per barrel as of April 10, down 12% from the week prior following the ceasefire announcement but still up 49.26% year-over-year, per Trading Economics. Saudi Arabia reported 600,000 barrels per day of production capacity offline from Iranian attacks, while the kingdom’s East-West Pipeline throughput fell by roughly 700,000 bpd. The US Energy Information Administration projects Brent could reach $115 per barrel in Q2 2026 if the Hormuz closure persists, with 9.1 million bpd of combined Gulf production (Iraq, Saudi Arabia, UAE, Kuwait, Qatar, Bahrain) shut in during April, according to the EIA’s April Short-Term Energy Outlook.
Iran’s total energy sector losses under sanctions have been estimated at roughly $60 billion annually in foregone investment and export revenues. Sanctions relief could unlock a 25-50% increase in oil and gas output, according to sanctions research data cited by Iran International. Trump administration officials have implemented a ‘Tehran Toll Booth’ policy under which Iran demands $1 per barrel in transit fees (approximately $2 million per supertanker), payable in Bitcoin or Chinese Yuan to bypass SWIFT sanctions.
Gulf States Fracture on Deal Strategy
Gulf capitals remain deeply divided on the talks. Saudi Arabia has signaled cautious support for restraint, while the UAE favours continued military escalation, according to Foreign Policy analysis. All four major Gulf States (Saudi Arabia, UAE, Qatar, Kuwait) absorbed thousands of Iranian missiles and drones during the February-April conflict. Their primary concern: any deal that legitimises Iranian nuclear enrichment and codifies Tehran’s control over the Strait of Hormuz could permanently shift regional leverage.
“The US must choose — ceasefire or continued war via Israel. It cannot have both.”
— Abbas Araghchi, Iranian Foreign Minister
The UAE views Iranian enrichment rights as an existential threat and has pressed Washington to maintain maximum pressure, while Saudi Arabia has adopted a hedging posture, quietly exploring détente with Tehran even as it repairs damaged oil infrastructure. Qatar, which shares the North Dome/South Pars gas field with Iran, has advocated for sanctions relief that could unlock $50 billion in joint energy sector capital reallocation.
Lebanon Dimension Threatens Framework
Iran’s insistence that the ceasefire include Lebanon has proven the most volatile variable. Israeli operations against Hezbollah continued uninterrupted after the April 7 announcement. The April 8 strikes, which Israeli officials described as targeting ‘command infrastructure,’ hit civilian neighbourhoods in Beirut and southern Lebanon. Foreign Minister Araghchi wrote on X that Washington ‘must choose — ceasefire or continued war via Israel. It cannot have both,’ per Al Jazeera.
The US delegation has argued that Lebanon falls outside the bilateral framework, framing Israeli operations as sovereign counterterrorism. Iranian negotiators reject this distinction, viewing Hezbollah as integral to regional deterrence architecture. Vance told reporters before departing for Islamabad that ‘if the Iranians are willing to negotiate in good faith, we’re certainly willing to extend the open hand,’ according to Al-Monitor. Trump warned on Truth Social that if Iran does not comply, then the ‘Shootin’ Starts,’ bigger and better and stronger than anyone has ever seen before,’ per Euronews.
What to Watch
The next 72 hours will determine whether the Islamabad talks produce a framework or collapse entirely. Key variables: whether Israel pauses Lebanon operations, whether Iran fully reopens the Strait, and whether the US accepts Iranian enrichment rights as Pakistan’s Prime Minister Shehbaz Sharif noted, ‘a temporary ceasefire has been announced, but now an even more difficult stage lies ahead: the stage of achieving a lasting ceasefire,’ according to Al-Monitor. Oil Markets will remain volatile: any resumption of strikes or Hormuz disruptions could push Brent above $100 within days. Gulf state positioning will clarify by mid-April, particularly whether Saudi Arabia and the UAE coordinate their Iran strategies or pursue divergent paths. The Lebanon front remains the most immediate risk — another large-scale strike could collapse the talks before substantive nuclear negotiations even begin.
