Vice President JD Vance will lead the U.S. delegation to Saturday's peace talks with Iran in Pakistan, marking the highest-level direct engagement between Washington and Tehran since the 1979 Islamic Revolution, White House press secretary Karoline Leavitt announced Wednesday.
The mission arrives at a critical juncture. Ceasefire negotiations have reached a breaking point where failure could trigger renewed and intensified conflict. For Vance, it represents the most consequential test of his political career and his stated commitment to pursuing diplomacy over military confrontation with Iran.
Vance struck a harder note while in Budapest on Wednesday, saying President Trump is "impatient to make progress" on Iran. "If Iranian officials don't engage in good faith," Vance warned, "they're going to find out that President Trump is not one to mess around with."
Trump adviser and son-in-law Jared Kushner and White House envoy Steve Witkoff will join Vance at the table. Iran's delegation will be led by Parliament Speaker Mohammad Bagher Ghalibaf and Foreign Minister Abbas Araghchi, according to Iranian state media.
The Ceasefire Framework Fractures
The talks enter turbulent waters. Israeli airstrikes in Lebanon have triggered fierce backlash from Tehran, which views the strikes as breaching ceasefire terms. Araghchi posted on X that Iran reserves the right to abandon the ceasefire if Israeli operations continue, declaring: "The Iran-U.S. Ceasefire terms are clear and explicit: the U.S. must choose, ceasefire or continued war via Israel. It cannot have both."
U.S. officials downplayed the threat. A senior American official said the administration is not currently worried the Lebanon strikes will derail negotiations. Leavitt clarified that "it has been relayed to all parties" that Lebanon falls outside the ceasefire agreement. Trump and Israeli Prime Minister Benjamin Netanyahu will continue discussions on the matter, but "for now Lebanon is not included," she said.
The dispute over Lebanon represents just one fracture in a broader disagreement about what the two sides actually agreed to. Trump posted on Truth Social on Wednesday that Iran's published 10-point framework differs substantially from the version presented to Washington, which will be discussed "behind closed doors" during the talks.
"These are the POINTS that are the basis on which we agreed to a CEASEFIRE," Trump wrote. "It is something that is reasonable, and can easily be dispensed with."
Leavitt confirmed reporting that Iran submitted a revised 10-point counter-proposal to the White House on Monday, which was rejected. Mediators then redrafted it to align with Washington's 15-point proposal. The press secretary alleged that Tehran maintains a significant gap between its public statements and private commitments, citing highly enriched uranium as an example. "We were given indications that they will turn over the enriched uranium," Leavitt said.
Ghalibaf painted a starkly different picture, claiming Iran has already identified three violations of the agreed framework. He pointed to the ceasefire breach in Lebanon, a drone incursion into Iranian airspace, and Trump's public statement denying Iran's enrichment rights, which Ghalibaf said was explicitly included in the original sixth clause. He argued that under these circumstances, "a bilateral ceasefire or negotiations is unreasonable."
The nuclear question looms as the paramount sticking point. Raz Zimmt, director of the Iran program at Israel's Institute for National Security Studies, told Axios that the talks must achieve three nuclear benchmarks to be considered successful: removal of Iran's 60 percent enriched uranium stockpile, dilution of 20 percent material to lower levels, and suspension of uranium enrichment for an extended period.
"If these demands are accepted, the war can end with at least one significant achievement," Zimmt said. "If the war ends with these nuclear capabilities still in Iran, it would constitute a major failure."
He noted that Iran rejected some of these same demands before the conflict intensified, making Saturday's negotiations extraordinarily high-stakes for all parties involved.
