Trump threats shake up U.S.-Iran talks in Switzerland on deal's details

U.S. Vice-President JD Vance is get together with top out iranian language officials on sun, as the edward d. White House looks to build out the interim deal to end the war in Iran reached by the two sides last week.

Vance was expected to meet with Tehran's negotiators, including parliamentary speaker Mohammad Bagher Ghalibaf and Foreign Minister Abbas Araghchi, at a Swiss mountainside resort near Lake Lucerne. Mediators from Pakistan and Qatar were also in the room for the direct engagement.

The framework was signed last week, and now top U.S. And Iranian negotiators are in a 60-day sprint to reach an agreement on the technical details that hold massive implications for the world economy and global security.

Yet only days after signing the agreement, it's being stress-tested after fighting escalated in Lebanon between Israel and the Iranian-backed militant group Hezbollah — and by the subsequent announcement by Iran's military that it had closed the Strait of Hormuz, the vital waterway that transits a fifth of the world's traded oil and natural gas.

Iranian officials appeared to avoid being seen during a brief appearance by Vance in front of reporters before the start of the talks. IRIB, the Iranian state broadcaster, announced the four-way talks, dubbed the Lake Lucerne Summit, had begun shortly after Vance delivered a statement to media and took questions from reporters.

"The question before us now is how much more can we accomplish together? Can we turn over a new leaf?" Vance said.

"Can we change relations in the Middle East permanently, or do we go back to doing things the old way, which is not our preference, but is certainly very much something that can happen?"

Soon after, U.S. President Donald Trump said in an online post that the U.S. will resume attacks on Iran unless the Iranians can keep their Hezbollah allies in Lebanon from causing violence.

"Iran must immediately stop their highly paid PROXIES in Lebanon from causing trouble," Trump wrote on Truth Social. "If they don’t, we’ll hit Iran very hard again, just like we did last week, only harder!!!"

Vance first sat down for talks with Pakistani Prime Minister Shehbaz Sharif and staff Field Marshal Asim Munir, who has served as a key intermediary between the United States and Iran throughout the conflict.

"What's up, man! Good to see you," Vance said as he warmly greeted Munir, who serves as Pakistan's army chief.

Rafael Grossi, chief of the UN nuclear watchdog — the International Atomic Energy Agency — met with Swiss Foreign Minister Ignazio Cassis on the sidelines of the gathering.

The agency had monitored the 2015 nuclear deal negotiated between the U.S. And Iran under the Obama administration. Trump withdrew the U.S. From the agreement in 2018.

JD Vance cancels trip to Europe for peace talks with Iran this weekend

Iran's main focus during negotiations on Sunday will be the ongoing war between Israel and Lebanon, Iranian Foreign Ministry spokesperson Esmail Baghaei told Iran's state news agency on Sunday.

Iran is insisting that the deal's implementation start with the part that calls for a cessation of all wars, including between Israel and Hezbollah. Baghaei said the U.S. "has been unable or unwilling" to hold Israel to the ceasefire.

Iran is cautiously approaching the negotiations given its previous experience with the U.S. Negotiations on the nuclear issue, which twice in the past year have been interrupted by massive strikes against the country. "The implementation of any document is more important than its signing," Baghaei said Sunday.

But Iran's president added that Iran will maintain its right to a nuclear program.

"What is certain is that we will never back down from the right to enrich uranium, and the other side is also forced to accept it," Iranian President Masoud Pezeshkian said on Sunday, according to Iran's state media.

Vance had originally been slated to be on the ground at Bürgenstock resort near Lucerne on Friday, but his departure from the United States was delayed after fighting escalated in Lebanon and Iranian officials cancelled plans to attend the talks.

U.S. Central Command disputed Iran's claim that it had once again shuttered the Strait of Hormuz and said U.S. Forces continued to monitor the situation to ensure traffic continues to flow through the waterway. Vance has said that millions of barrels of oil have moved through the strait in recent days.

The vice-president was joined by special envoy Steve Witkoff and Jared Kushner, Trump's son-in-law, for Sunday's talks. Witkoff and Kushner were on the ground in Switzerland ahead of Vance to begin sifting through the technical details of the nuclear talks.

Vance and his wife, Usha Vance, arrived at Emmen Air Base outside Lucerne just before 6 a.m. Local time, according to his office.

While Vance said he planned to be in Switzerland for just "a day or two," leaving much of the detailed negotiations to be spearheaded by Witkoff and Kushner, his role in the talks has heightened scrutiny of the vice-president at a time when he's actively considering a 2028 presidential campaign.

Trump and Vance have come under searing criticism from parts of their own party for the deal, with Republican hard-liners unfavourably likening it to a nuclear agreement signed by the Obama administration that Trump and the GOP have insisted did nothing to actually terminate Iran's nuclear program.

The agreement signed by Trump and Pezeshkian immediately allows Tehran to sell its oil freely and paves the way for Iran to tap into billions of dollars in assets that are currently frozen. It also calls for Iran to dilute its stockpile of highly enriched uranium, believed to be buried under nuclear sites that were targeted in U.S. Strikes last summer.

The agreement says commercial vessels can pass through the Strait of Hormuz for 60 days without a charge, but does not preclude future fees imposed by Iran. Trump made his own threat on Saturday to levy U.S. Tolls on the strait if there is no deal with Iran in 60 days, insisting in a social media post that the money would be for "services rendered as the Guardian Angel to the countries of the Middle East."

Trump routinely trashes the Obama-era Iran nuclear agreement. How is his deal different?

The Trump administration has been working to reassure global markets that the Iran war has been merely a blip on oil prices, as Americans have complained the conflict resulted in hiking gasoline prices ahead of peak summer travel months.

Further complicating matters, neither Israel nor Hezbollah are signatories to the deal between the U.S. And Iran, and Israeli Prime Minister Benjamin Netanyahu has vowed to keep his forces in southern Lebanon until any threat to Israel is eliminated. Hezbollah has refused to halt its attacks unless Israel commits to withdrawing from Lebanon.

Fighting between Israel and Hezbollah in the initial days after the agreement between the U.S. And Iran killed 47 people in Lebanon, as well as four Israeli soldiers.
