US-Iran nuclear talks: high-stakes negotiations in Switzerland amid Strait of Hormuz closure and fragile ceasefire

US Vice President JD Vance and Iranian parliamentary speaker Mohammad Bagher Ghalibaf lead delegations to Bürgenstock, Switzerland, for talks on implementing a fragile memorandum of understanding (MOU) that aims to halt hostilities and reopen the Strait of Hormuz. The talks follow a chaotic period marked by initial Iranian cancellation over Israeli strikes in Lebanon, conflicting claims about the strait's status, and domestic criticism of the deal in Washington. Both sides emphasize priorities: the US focuses on nuclear issues and Lebanon ceasefire, while Iran stresses sanctions relief and economic recovery. Mediators including Pakistan, Switzerland, and Qatar are involved. The talks occur against a backdrop of high oil prices and midterm election pressures in the US.
