US-Iran Talks Collapse After 21-Hour Islamabad Session, Threatening Hormuz Strait

US-Iran peace talks collapsed after a 21-hour marathon session in Islamabad on April 12, Vice President JD Vance announced. Iran rejected US terms, endangering the two-week ceasefire and freedom of navigation in the Strait of Hormuz, which handles 20% of global oil exports. US Navy ships transited the strait for the first time since February 28, with three supertankers exiting the Gulf on April 11.
