When President Trump came to office in 2017, he inherited from President Obama the Iran Nuclear Deal. Trump rejected the deal and embarked on a fruitless "maximum pressure" campaign against Iran.  Such is the state of relations between the United States and Iran that Joe Biden will inherit when he takes office in January. Trita Parsi of the Quincy Institute discusses whether or not it is even possible for a Biden administration to revive the nuclear deal; and what steps a Biden administration can take to get diplomacy with Iran back on track.
