Atlantic Council Senior Adviser Harlan Ullman writes for United Press International on the challenges facing the Obama administration during the Congressional review of the Iran nuclear deal:
Make no mistake: the intense debate and negotiations over the P5+1 nuclear agreement with Iran are just beginning. However difficult the talks in Switzerland and Austria over the past four years may have been, the coming months will make that pothole-filled road look like a modern eight-lane super highway. Certain members of Congress abetted by the Israeli government and its American supporters will do their level best to kill the Joint Comprehensive Plan of Action (JCPOA).
That said, how might this controversy play out? Congress has sixty days to review the agreement and then vote on it. At this stage, it seems unlikely that if Congress were to vote against the JCPOA and President Barack Obama vetoed the legislation, that veto would not be overridden in the Senate where sixty-seven votes are needed for the required two-thirds majority. But if the veto were overridden, how would the other signatories react? And what will be the effect of the United Nations having lifted sanctions when the United States did not?
