Vance leads US-Iran peace talks in Switzerland amid Trump Threats and bipartisan Criticism

US Vice President JD Vance led high-stakes peace talks with Iranian chief negotiator Mohammad Bagher Ghalibaf in Switzerland to finalize a 60-day nuclear and security framework. The negotiations faced immediate disruptions from President Donald Trump's inflammatory threats to strike Iran and block its delegates from returning home. While negotiators agreed to a de-confliction cell for Lebanon, the deal faces severe bipartisan backlash in Congress and resistance from Israel, which refuses to withdraw from southern Lebanon.
