The Biden administration's efforts to revive the 2015 nuclear accord with Iran are on the brink of collapse, leading experts to fear the two countries could enter a new era of suspicion and even outright conflict. Since 1979 the U.S. and Iran have had no formal diplomatic ties, their relationship marked by distrust and hostility. The ongoing animosity has created a self-fulfilling prophecy where Iran is now closer to having enough enriched uranium to build a bomb than it had before the U.S. pulled out of the 2015 deal. In this episode, historian John Ghazvinian and foreign policy expert Trita Parsi discuss the potential consequences for the world if the latest negotiations end in failure.
