Insulted by Trump's Threats, Iranian Negotiators Walk Out of Peace Talks

"Don’t they think that if their threats had worked, they wouldn’t have ended up in today’s desperate situation?" said Iran's chief negotiator.

US President Donald Trump’s threats to destroy Iran and send US forces to occupy the country on Sunday appear to have derailed peace negotiations in Switzerland, with the Iranian delegation reportedly walking out and demanding an apology.

Following Iran’s announcement that it was closing the Strait of Hormuz again after Israel intensified its assault on Lebanon, Trump went on a tirade Sunday in which he threatened to assassinate negotiators and said Iran “won’t have a country” if access to the critical waterway was shut off, while also threatening to “take over” Iran with a full US invasion.

But after Trump’s threats—which broke the first clause of the memorandum of understanding—Iran’s negotiators filed a complaint with the Pakistani and Qatari mediators and stormed out of the mountain resort where talks were being held, according to several outlets.

While Trump clearly sought to project strength, Iran’s chief negotiator, Mohammad Bagher Ghalibaf, said his team “do not take American threats seriously.”

In previous months, as Trump sought to squeeze concessions from the Iranians, he issued escalatory threats to wipe out their “whole civilization” and “blow up” the whole country. However, he did not act on those threats, even as Iran refused to budge from its negotiating posture.

"Don’t they think that if their threats had worked, they wouldn’t have ended up in today’s desperate situation?" Ghalibaf said.

Ghalibaf said the US had “better be more careful with their statements,” adding that “our armed forces are ready to respond in a different way." He said, “No matter what they say, we are the ones who act.

While the Iranian delegation left the venue, talks are reportedly continuing via mediators. However, according to the Lebanese outlet Al Mayadeen, the delegation said it will not return until Trump apologizes for his threats and Israel fully withdraws from Lebanon.

According to senior Israeli officials cited by Channel 12, Israel is reportedly considering “limited withdrawals” from Lebanon, including in areas within its so-called “buffer zone.” Despite Iranian claims, the officials said the US has not requested Israel’s withdrawal from the country.

Previous peace talks have been derailed by Trump’s threats to commit indiscriminate war crimes in Iran. But this past week has seen perhaps the most violent swing yet in his approach toward Iran.

Where earlier this week, Trump acknowledged Iran's right to enrich uranium and maintain a nuclear energy program like that of other nations, his outburst Sunday appeared to have been prompted by a statement by Iranian President Masoud Pezeshkian, who said the US would be "forced to accept" its right to enrichment.

And while Trump has raged against Israel’s actions in Lebanon while privately claiming that Prime Minister Benjamin Netanyahu is trying to sabotage peace, he has not taken concrete action to force Israel to comply with the memorandum’s terms.

"The mixed messages coming out of the White House," remarked Jeet Heer, a writer at The Nation, "are going to make it much harder to end the war, and could in fact spark further conflict."
