President Trump is widely expected to decertify the Iran Nuclear Deal. But what decertification actually mean? And will this action destroy the Iran Nuclear Deal? On the line with me to discuss these questions and more is Spencer Ackerman, the Pulitzer Prize winning reporter with the Daily Beast.   It's becoming increasingly clear that even if this White House action does not result in the re-imposition of US sanctions, which could kill the deal, it nonetheless undermines American credibility among both America's allies and adversaries around the world. The diplomatic fallout from this move will be far and wide. As Ackerman puts it, this action "cannot be cauterized" from any other aspect of American diplomacy.     Ackerman recently wrote about the likely diplomatic fallout from this action, which we discuss in depth.   If you have 20 minutes and want to learn about the broader implications of this move by President Trump, have a listen.    Become a premium subscriber to unlock bonus episodes, earn other rewards, and support the show!
