Trump gives Iran a narrow window to unite for peace talks

Trump has given Iran's rival factions a three-to-five day window to present a unified counter-offer and return to talks or risk ending the extended ceasefire, as U.S. officials say a split between Iran's negotiators and the IRGC threatens a deal to end the war and address its nuclear program; Pakistan-mediated talks and Tehran's silence have frustrated the White House, which still relies on the naval blockade as leverage and notes military options could return if diplomacy fails.
