Five former members of President Obama’s inner circle of Iran advisers have written an open letter expressing concern that a pending accord to stem Iran’s nuclear program “may fall short of meeting the administration’s own standard of a ‘good’ agreement” and laying out a series of minimum requirements that Iran must agree to in coming days for them to support a final deal.

Payam Mohseni, Director of the Iran Project at the Belfer Center for Science and International Affairs, Dennis Ross, International Council Member, Belfer Center, and David Sanger, Senior Fellow at the Belfer Center, discuss for The New York Times the stakes in the current Iran nuclear negotiations, including the risks of lifting sanctions on Iran, the difficulties in reaching an agreement, and the importance of the current political moment for both Iran and the U.S. in reaching a deal.
