Biden shelves Iran nuclear talks
January 2021: Biden expressed support for a new nuclear deal with Iran upon taking office, though members of his administration have questioned whether he was truly committed to the talks, which showed some initial progress but fizzled out.
October 2022: The Biden administration said it would not "waste time" on trying to revive the nuclear deal because of several concerns with Iran.
December 2022: Biden, at an election rally, said that the nuclear deal with Iran was "dead" but that the U.S. wouldn't formally announce it.
This marked the strongest confirmation that the Biden administration believed there was no path toward reaching a deal.
"The JCPOA is not our focus right now. It's not on the agenda," a White House National Security Council spokesperson told Axios at the time.
February 2023: United Nations inspectors reported that Iran enriched trace amounts of uranium to nearly weapons-grade levels.
