yup, they got it from Jared

think about it. Any country's negotiators will have 2nd thoughts about the trust factor from the US.

We need to ask the question that official Washington is too timid, too compromised, or too captured by the moment’s war fever to ask: “Was Jared Kushner sitting across from Iranian negotiators in good faith? Or was he trying to get the Iranian leadership to meet together so Netanyahu could kill them all in one single decapitating strike?”

On the morning of Feb. 28th, Iran’s Supreme National Security Council was gathered together in their offices for meetings. That body, the one that manages Iran’s nuclear dossier and makes the regime’s most consequential decisions, is exactly where you would expect the Iranian leadership to be sitting after a round of talks with America that their own foreign minister was calling “historic.”

They were almost certainly deliberating whether to accept or reject Kushner's American proposal. And according to the Wall Street Journal, American and Israeli intelligence had verified that senior Iranian leaders would be gathered at three locations that could be struck simultaneously. How they knew that is, as the Journal carefully noted, still unknown.

Diplomats who were part of the earlier rounds of talks now tell reporters that the Iranian side has come to believe they’d been misled, and that Tehran now views the Witkoff-Kushner negotiations as, in their words, “a ruse designed to keep Iran from expecting and preparing for the surprise strikes.”
