Trump threatens to 'hit Iran very hard again' while Vance in Switzerland for talks

NPR reports that President Trump threatened to 'hit Iran very hard again' while Vice President JD Vance attended diplomatic talks with Iranian officials in Switzerland on Sunday, according to Trump's social media posts. The threats appear tied to Iran's proxy activities in Lebanon and its actions in the Strait of Hormuz, occurring days after a newly signed interim peace deal between the US and Iran. NPR is a major national outlet with established editorial standards; the article includes a named byline (Chandelis Duster), and corroboration from CNN, Guardian, NBC News, and Al Jazeera confirms the core facts—that talks were underway, Trump issued threats via social media, and regional tensions (Israeli strikes on Lebanon, Iranian threats to shipping) are straining the recent agreement. The reporting shows adequate sourcing for the headline claim, though the NPR metadata provided lacks specific quotes or named officials beyond Trump's social media statement. Watch for developments in the Switzerland negotiations and whether Trump's threats affect Vance's diplomatic progress, as well as escalation risks in the Strait of Hormuz and Lebanese theater given the stated vulnerabilities to the deal.
