US-Iran negotiations for a permanent peace deal, mediated by Pakistan, remain stalled despite Iran's April 28 proposal to reopen the Strait of Hormuz and delay nuclear talks, which the Trump administration is reviewing. Core disputes center on US demands for Iran to surrender its highly enriched uranium stockpile, full sanctions relief, ballistic missile curbs, and verifiable nuclear moratoriums—issues echoing past JCPOA tensions. A fragile two-week ceasefire, extended after US naval actions blocking Iranian ports, holds amid rising oil prices and escalation risks from regional proxies. No breakthrough occurred by late April deadlines, with upcoming mediated sessions offering slim chances for progress before potential renewed hostilities.
