Why are US-Iran talks being held in Islamabad?

Pakistan offered to serve as a neutral mediating venue for the talks, with Pakistani Prime Minister Shehbaz Sharif facilitating sessions. Egypt and Turkey are also participating as co-mediators. The first round ran 21 hours on 11–12 April 2026 without a deal; the second round began on 21 April.

What are the main sticking points in the negotiations?

Three issues remain unresolved as of 21 April 2026: Iran's nuclear enrichment timeline (the US demands a 20-year moratorium; Iran offered five years), caps on Iran's ballistic missile program, and control of the Strait of Hormuz. The US Navy blockaded the strait in early March, and Washington wants formal Iranian recognition of international maritime oversight as a condition of any deal.

What happens if no deal is reached before the ceasefire expires?

President Trump has stated the ceasefire expires Wednesday evening, Washington time, and that a further extension is "highly unlikely." If talks collapse, the air war over Iranian nuclear and military sites — paused since the ceasefire was signed 30 March 2026 — would likely resume. Goldman Sachs estimated on 21 April that ceasefire failure would send Brent crude back above $120 per barrel within 24 hours.

How does Israel factor into the US-Iran deal?

Israeli Prime Minister Benjamin Netanyahu said on 20 April 2026 that Israel has "unfinished work in Iran" and would not be bound by a deal that stops short of dismantling Tehran's nuclear weapons capability. Israel has conducted at least 14 independent strikes on Iranian military infrastructure since October 2025, and its consent to any framework has not been formally secured by the US delegation in Islamabad.

US-Iran Talks Resume Before Ceasefire Expires

JD Vance led a US delegation into second-round nuclear talks in Islamabad on 21 April as Trump warned the ceasefire expires Wednesday evening.

ISLAMABAD — Vice President JD Vance arrived in Pakistan's capital Tuesday for a second round of nuclear negotiations with Iran, touching down in Islamabad on 21 April 2026 less than 36 hours before President Donald Trump's bilateral ceasefire with Tehran is scheduled to expire Wednesday evening, Washington time.

Special envoy Steve Witkoff and senior adviser Jared Kushner joined Vance in the US delegation. Pakistan's government, hosting the talks for the second consecutive session, deployed Foreign Minister Ishaq Dar as chief interlocutor alongside Egyptian Foreign Minister Badr Abdelatty and Turkish Foreign Minister Hakan Fidan, who flew into Islamabad on 20 April to assist in bridging the remaining gaps. Iran sent Foreign Minister Abbas Araghchi, whose flight from Tehran landed at Islamabad International Airport just over an hour before formal sessions were set to begin. "Iran does not negotiate under the shadow of threats," Araghchi told reporters outside the terminal on 21 April — a formulation his government has used consistently since the first round collapsed eleven days earlier.

Trump set the tone from Washington before dawn on Tuesday. On Truth Social, he wrote that the ceasefire — signed 30 March 2026 after six weeks of open conflict between US forces, Israel, and Iranian military assets — was "going away Wednesday evening, Washington time" unless a deal was signed. He added that a further extension was "HIGHLY UNLIKELY" and that any agreement he reached would be "FAR BETTER than the JCPOA," a reference to the 2015 Iran nuclear deal negotiated under the Obama and Biden administrations.
