Ali Gholhaki, a conservative analyst close to the Iranian government, said on social media that talks fell apart because the United States demanded zero enrichment, removal of nearly 900 pounds of stockpile uranium from the country and U.S. “management of the security of the Strait of Hormuz on their own terms.” Mr. Gholhaki said the United States also provided no commitment to end Israel’s bombing of Lebanon. “It seems the Americans didn’t come to negotiate!” he said.
