President Obama may not be terribly realistic about his negotiating partners in Iran, but he has a firm grip on political reality in the United States. If he wants to get Congress to approve his pending nuclear deal with Iran he knows that demonstrating his concern for Israel’s survival is just as if not more important than explaining away the glaring weakness in the agreement. He tried to just that in a friendly interview with the Atlantic’sJeffrey Goldberg though he was tripped up, as our Noah Rothman noted, by an utterly unconvincing dismissal of the importance of the anti-Semitic nature of the Iranian regime. But the most curious thing about the interview was the way Goldberg took the as yet unwritten terms of the deal as a given rather than very much up in the air until they are put on paper. What we really need to know is not just how badly Obama wants to pretend that he cares about Israel but whether the agreement he is supposed to present to Congress sometime this summer will resemble the already admittedly weak one he spoke of when the framework deal was announced last month. And it is in the struggle for those final terms that Obama is once again being taken to the cleaners by an Iranian leadership that may or many not be rational, but is certainly more skillful at negotiation than the president.
