US and Iran trade threats as historic talks in Switzerland collapse within hours
US President Donald Trump on Sunday threatened to strike Iran if it did not immediately halt Hezbollah’s activities in Lebanon, prompting the Iranian delegation to walk out of the first round of direct talks in Switzerland aimed at ending the regional war.
Vice President J.D. Vance and senior US envoys met Iranian Speaker of Parliament Mohammad-Bagher Ghalibaf and Foreign Minister Abbas Araghchi at the Bürgenstock ski resort near Lake Lucerne, but the session ended abruptly after Trump’s Truth Social post warned Iran to “stop their highly paid PROXIES in Lebanon from causing trouble” or face “very hard” retaliation “only harder!!!”
Iran’s chief negotiator Ghalibaf had earlier warned Washington to “be careful with their statements,” and Iranian state media reported that the delegation delivered a formal protest to US mediators and left the venue in protest.
The talks, brokered by Pakistan and Qatar, were intended to launch 60 days of nuclear negotiations and address the Israeli-Hezbollah conflict in Lebanon, where fighting continued despite a fragile ceasefire. Vance told reporters that “we already made progress in the last several hours” and expected further advances, but the Iranian withdrawal cast immediate doubt on the process.
Iran’s Foreign Ministry had insisted the discussions would focus on a Lebanese ceasefire, US oil sanctions waivers, and the release of frozen funds, while US negotiators sought UN access to Iranian nuclear sites bombed by Israel and the US in 2025. A potential quid pro quo involved releasing a $6 billion Iranian fund in Qatar for humanitarian purchases.
Trump’s latest rhetoric escalated tensions hours after Israeli strikes on Lebanon resumed, which Iran cited as justification for threatening to close the Strait of Hormuz. Iranian Supreme Leader Ali Khamenei has expressed reservations about the interim deal, though most top decision-makers reportedly support it.
The abrupt collapse underscores the fragility of the diplomatic process, with both sides trading ultimatums even as mediators warned that the window for a lasting agreement could close within days.
