U.S. State Department’s Deputy Secretary Tony Blinken joins MSNBC’s Morning Joe and states the case for why the nuclear deal reached between the U.S. and Iran is the best possible option. “If the U.S. Congress managed to turn this deal down, what restraints, if any, would then be imposed on Iran? What cooperation, if any, would we receive from the P5+1 countries in terms of military action? And what restraints, if any, would there be on imposing sanctions on Iran?,” asks Mike Barnicle of the possible scenarios should the deal ultimately not be approved by the U.S. government.
