Iranian officials continue to demand wholesale sanctions relief from the United States, a posture that portends a final collapse of talks billed as a “last chance” to rehabilitate the 2015 Iran nuclear deal.

“From our point of view, the sanctions, which are in contradiction and inconsistent with the [Joint Comprehensive Plan of Action], need to be removed immediately,” Iranian nuclear negotiator Ali Bagheri Kani told state media. “These sanctions have been imposed either during the Obama, Trump, or Biden administrations. All of them need to be removed.”
