ZURICH (AP) — The U.S. push to quickly begin high-stakes talks with Iran hit a snag just two days after the signing of an agreement that opens a 60-day window to negotiate a permanent understanding about Iran’s nuclear program while getting oil traffic moving through the Strait of Hormuz back to prewar levels.
Vice President JD Vance had been prepared to make an overnight flight Friday to meet with his Iranian counterparts at a mountainside resort in the tiny Swiss village of Obbürgen and begin the technical talks.
His staff and a small pack of journalists had even gathered at Joint Base Andrews outside Washington in anticipation of the trip. Meanwhile, dozens of White House officials, advance staffers and more media gathered in Switzerland to prepare for Vance's anticipated arrival.
But then abruptly on Thursday evening the trip was called off — at least for the time being.
The White House issued a statement explaining Vance — who has been tapped by President Donald Trump to lead the negotiations — and his delegation were prepared for talks, but they were unable to finalize plans and the vice president would remain in Washington.
“The logistics of these negotiations have never been simple or predictable,” the statement noted.
The announcement followed a report from Al-Mayadeen, a Pan-Arab satellite channel that is politically allied with the Iranian-backed Lebanese militant group Hezbollah, that Iran was delaying sending its delegation to Switzerland over Israel’s ongoing military campaign in Lebanon.
Israeli Prime Minister Benjamin Netanyahu said Thursday that Israel’s military will stay in a “security zone” of southern Lebanon as long as “Israel’s security needs require it.”
Israel and Hezbollah are not parties to the agreement. Iran insists Israel must withdraw from the large swath of southern Lebanon it is occupying, but the wording of the interim deal doesn’t explicitly require that and only ensures Lebanon’s “territorial integrity.”
Hours before postponing his trip, Vance gave some indication of the state of flux when he told reporters at a White House briefing that he was uncertain if the talks were going to happen this weekend.
“Our plan is to go to Switzerland, I don’t know exactly when,” Vance told reporters. “We think these technical negotiations start sometime this weekend. That’s still the plan. But that could change.”
Soon after Vance spoke to reporters, Iran's Supreme Leader Ayatollah Mojtaba Khamenei endorsed direct negotiations with the U.S. in a terse statement read by state media that appeared to signal to the Islamic Republic’s leadership that it could move forward with a first round of talks.
“It is obvious that the face-to-face negotiations that will be held in the future will not mean accepting the enemy’s opinion,” Khamenei said in his statement.
The messaging seemed to give Khamenei, who was badly wounded in the Feb. 28 U.S. strike that killed his father, some maneuverability. Hard-liners in the Iranian government, including Khamenei’s father, have long opposed direct talks with the White House, especially after Trump, during his first term, pulled out of the 2015 nuclear deal negotiated by Democratic President Barack Obama's administration.
More importantly for the White House, it appeared to create a permission structure for the talks to start.
Vance was initially expected to go to Switzerland to sign the agreement at a formal ceremony. Instead, Trump signed the document Wednesday during a glitzy dinner at the Palace of Versailles with French President Emmanuel Macron, and Iranian President Masoud Pezeshkian separately signed the agreement.
The agreement states that Iran’s stockpile of highly enriched uranium, which is believed to be buried under rubble left by U.S. military strikes last year targeting Tehran’s key nuclear sites, must at minimum be diluted under international supervision.
It also states that Iran shall not procure or develop nuclear weapons — a commitment it has made previously. But a range of other commitments remain to be worked out.
Iranians would be going into the talks with a measure of confidence after effectively shutting down the Strait of Hormuz, causing global economic reverberations, said Rosemary Kelanic, director of the Middle East Program at Defense Priorities in Washington.
She said the U.S. is now “essentially trying to negotiate our way back to the prewar status quo."
Neil Quilliam, an associate fellow with the Middle East and North Africa Program at Chatham House think tank, said the “buoyant” Iranian leadership feels it has the upper hand. The endorsement of the talks by the Iranian supreme leader “sends a very strong signal domestically: ’We’re now on an equal footing with the U.S.'”
”‘Trump has gone from calling for regime change on Feb. 28 to this: Now they’re going to sit down with us directly and talk about these big issues,'” Quilliam said of the Iranians' thinking. “So it’s intended more for the domestic audience, and telling them: ‘We are firmly in control of this. There can be no protests, no revolution: We are a new regime and we’re staying put.’”
The president's tone has also taken a notable shift.
For weeks, he's insisted the financial costs to Americans were less important to him than stamping out Iran's nuclear program. He irked some of his fellow Republicans when he indicated its potential impact on November's midterm elections wasn't a concern.
But this week, at the G7 summit in Evian-Les-Bains, France, he acknowledged for the first time that continuing the war could have led to “economic catastrophe” and that oil reserves were on track to run out in about four weeks.
“And the one president I did not want to be was the late, great Herbert Hoover,” said Trump, referring to the 31st president whose time in office was defined by the Great Depression.
For Vance, a likely 2028 presidential contender, how the negotiations play out could have enormous ramifications for his political fortunes.
Vance's skepticism of foreign wars was a core part of his political identity during his political rise. But now he finds himself the chief defender of negotiating an endgame to Trump's conflict that Democrats have largely derided as a foolish gambit. Some hawkish Republicans are aghast that Trump is getting behind a settlement that could put billions of dollars into Iran's coffers.
Sen. Roger Wicker, the Republican chairman of the Senate Armed Services Committee, said Thursday that he’s concerned the agreement “negotiates away the victories" from the U.S. air campaign against Iran and said aspects of it are “completely out of step” with Trump's goals.
Trump had fiercely criticized Obama for the 2015 nuclear agreement, which Trump argued failed to stop Tehran from advancing toward a weapon and funneled billions of dollars to the Islamic Republic.
In 2018, Trump exited the deal, known as the Joint Comprehensive Plan of Action. Britain, China, France, Germany, Russia and the European Union were also signatories to the pact.
Trump has pushed back against comparisons to the JCPOA, saying he had “negotiated from strength” after a massive military campaign while asserting that Obama was paying the Iranians off and not receiving acquiescence.
Wicker was particularly concerned about the $300 billion fund for the reconstruction and economic development of Iran mentioned in the 14-point agreement, saying it "would make Iran’s payoff under Obama’s 2015 deal look like a pittance by comparison.” Trump and Vance have said no U.S. taxpayer money would go to such a fund and it would not come without concessions and reforms by Tehran.
