US-Iran talks postponed as Vance cancels trip and Israeli strikes on Lebanon escalate
The first peace talks between the United States and Iran were postponed Friday, as Vice President JD Vance canceled his planned travel to Switzerland and Israeli forces intensified strikes in southern Lebanon. The delay is the most concrete sign yet that the fragile ceasefire framework signed this week is coming apart under the weight of the conflict it was meant to end.
Iran has told U.S. mediators it will not resume negotiations until it receives guarantees that Israeli attacks on Lebanon will stop. Tehran holds that the ceasefire the memorandum of understanding established applies on all fronts, including Lebanon. The Israeli government maintains it has the right to strike Hezbollah targets in southern Lebanon regardless of the U.S.-Iran deal, a position Prime Minister Netanyahu reiterated Friday.
The talks were scheduled to begin the formal process of cementing the ceasefire and opening the next phase of negotiations on Iran’s nuclear program. Vance was to lead the U.S. delegation to Switzerland. His cancellation was confirmed by administration officials Friday morning, who said the trip was “delayed” rather than canceled outright, a distinction that does little to mask the diplomatic paralysis.
On the ground, the contradiction is plain. Israel conducted new strikes in southern Lebanon on Friday, hitting what it described as Hezbollah rocket launchers and observation posts near the town of Nabatieh. Hezbollah responded with rocket fire toward Israeli positions along the border. The exchange was the latest in a cycle of violations that has accelerated since the deal was announced on Sunday. The Israeli military said it had struck more than 30 Hezbollah targets in the past 48 hours, including launchers, command posts, and weapons storage sites.
Iran’s Foreign Ministry reiterated Friday that continued Israeli attacks on Lebanon constitute a breach of the ceasefire. “The ceasefire between Iran and the US is unequivocally a ceasefire on all fronts, including in Lebanon,” the ministry has said repeatedly, a position it has not changed despite the deal signing.
Defense Secretary Pete Hegseth added to the uncertainty on Friday, warning during a press conference in Brussels that the United States would restart military action against Iran if the deal collapsed. “We have not removed our capability to strike,” Hegseth said, making clear that the Pentagon views the ceasefire as conditional on full Iranian compliance. The statement appeared aimed at reassuring Israel that the U.S. military option remains on the table, but it also undercuts the administration’s claim that a durable peace has been achieved.
The postponement creates a cascade of problems. The 60-day implementation phase of the MoU, which includes reopening the Strait of Hormuz to commercial shipping and swapping prisoners, cannot proceed without direct talks. Iranian oil tankers have already left the blockade zone, but the broader economic relief the deal was supposed to deliver depends on negotiations that are now on hold. The United Nations had been preparing to facilitate the next stage of talks, and Swiss diplomats had confirmed Geneva as the venue. All of that planning is now suspended.
It leaves the Trump administration in a difficult position. The deal was presented at the G7 summit as a historic breakthrough, the moment the United States brought peace to the Middle East. In practice, the agreement depends on two conditions that remain unmet: Israel’s willingness to halt operations it considers essential to its security, and Iran’s willingness to accept a ceasefire that does not stop those operations. Neither condition is currently satisfied.
