Iran’s delegation in Islamabad concluded a 21‑hour meeting with U.S. officials without reaching agreement, arguing the Americans sought to impose terms rather than negotiate.

Vice President JD Vance declared the U.S. had “made very clear what our red lines are,” while former diplomat Javad Zarif blasted the effort as a one‑sided demand.

Iran’s focus centers on the Strait of Hormuz, a vital oil corridor whose control could yield substantial revenue and strategic leverage. The government insists it will not cede any authority, maintaining that the U.S. cannot dictate outcomes.

With military strikes still looming, Tehran believes it can endure further bombardment longer than Washington anticipates, potentially forcing a costly economic standoff for the U.S. that could reshape regional trade flows.
