US and Iran strike Lebanon de-escalation deal in 60-day window

The US and Iran agreed Sunday to create a joint de-escalation mechanism for Lebanon, the first concrete outcome from high-level talks in Switzerland that mediators said delivered "encouraging progress" toward a permanent settlement of the West Asia crisis.

"Tireless Pakistani and Qatari mediation has delivered major progress to end the Lebanon War," Iranian Foreign Minister Abbas Araghchi wrote on X after the talks. "Oil and petrochem exports are waived, the blockade lifted, some frozen assets released, and a major reconstruction and development plan launched for Iran."

The agreement establishes a de-escalation cell involving the Lebanese government to monitor compliance with the termination of military operations in Lebanon, according to a joint statement from Pakistan and Qatar. Technical talks will continue this week at the Burgenstock resort, with a High Level Committee providing political oversight on the mediation. The negotiations are part of a 14-point memorandum of understanding signed last week between Washington and Tehran, which opened a 60-day window for talks covering Iran's nuclear program, sanctions relief, and the Strait of Hormuz.

The stakes extend well beyond Lebanon. The Strait of Hormuz handles about 21 percent of global oil trade, and Iran's weekend claim that it had again shut the waterway — disputed by the US — showed how quickly the talks could unravel. Oil futures dropped almost 8 percent after the interim deal was announced last week, reflecting market hopes for de-escalation, but Trump's threats injected fresh uncertainty.

The talks nearly collapsed before they began. Trump posted on Truth Social early Sunday that Iran "must immediately stop their highly paid PROXIES in Lebanon from causing trouble. If they don't, we'll hit Iran very hard again, just like we did last week, only harder." The threat drew an immediate rebuke from Iran's lead negotiator, Parliament Speaker Mohammad Bagher Qalibaf, who warned that Iran's armed forces were prepared to respond. CNN reported that Iranian negotiators threatened to walk out, with back-channel discussions needed to keep the talks alive.

Vice President JD Vance, leading the US delegation alongside Steve Witkoff and Jared Kushner, met with Qalibaf and Araghchi for about 80 minutes at the Lake Lucerne Summit. A photo released by mediators showed Vance working on a laptop alongside Qatar's prime minister and Kushner, with a coffee machine visible in the background — an image that captured the improvised nature of the diplomacy.

Lebanon remains the flashpoint

The de-escalation cell faces its first test in Lebanon, where Iranian-backed Hezbollah has been trading fire with Israeli forces occupying southern Lebanon. Neither Israel nor Hezbollah is a signatory to the US-Iran agreement, and Israeli Prime Minister Benjamin Netanyahu has vowed to maintain military operations until threats to northern Israel are eliminated. Araghchi acknowledged the challenge, calling the Lebanon cell the "first real test" of the accord.

A senior US diplomat involved in the talks said the discussions also covered mechanisms to ensure the Strait of Hormuz remains open and addressed "all elements" of a prospective nuclear agreement. The diplomat expressed optimism about the initial round, telling Axios the talks were "setting us up for trust-building going forward."

The last time Washington and Tehran engaged in direct nuclear negotiations was under the Obama administration's 2015 Joint Comprehensive Plan of Action, which Trump withdrew from in 2018. The current talks take place against a far more volatile backdrop: US airstrikes a year ago targeted Iranian nuclear sites buried deep underground, and Iran has since enriched uranium to levels approaching weapons-grade, according to the International Atomic Energy Agency.

For global markets, the path forward hinges on whether the de-escalation cell can deliver a verifiable halt to hostilities in Lebanon and whether technical talks on the Strait of Hormuz and nuclear program can produce breakthroughs before the 60-day window closes. Trump has warned he may impose US tolls on ships passing through the strait if no deal is reached, while Iran's President Masoud Pezeshkian declared Sunday that Tehran "will never back down from the right to enrich uranium."
