Iranian officials negotiating a peace-related agreement with the United States in Switzerland nearly leave the talks after criticism and warnings posted by U.S. President Donald Trump, according to one outlet. The reports say the Iranian delegation reacts to the posts by considering walking out during the negotiations. The situation is described as escalating after Trump’s messages, which include warnings that the talks could be jeopardized. U.S. figures, including JD Vance, respond to the situation, disputing Iran’s stance and characterizing the exchange in a confrontational way, while the Iranian side reportedly signals reluctance to continue if the atmosphere remains hostile. The accounts also frame the incident as connected to the broader US-Iran negotiation context and the difficulty of keeping formal talks on track amid public statements. Across the coverage provided, the central point is that the Iranian team’s participation is disrupted—or threatened—by the impact of Trump’s public messaging during the Swiss negotiations. The reports do not provide additional confirmed details on the substance of the peace proposal or whether the delegation ultimately departed.
