Dennis Ross: Obama needs to answer Netanyahu

"Prime Minister Benjamin Netanyahu made a strong case to the Congress about why he thinks the potential agreement with Iran on its nuclear program is a "very bad deal."

While the Obama administration is unlikely to accept his argument that it should simply negotiate better and harder, it should not dismiss the concerns he raises about the emerging deal. Indeed, the administration argument that there is no better alternative than the deal it is negotiating begs the question of whether the prospective agreement is acceptable.

And, here, the administration needs to explain why the deal it is trying to conclude actually will prevent Iran from getting nuclear weapons for the life-time of the agreement and afterwards. It needs to explain why the combination of the number and quality of centrifuges, their output, and the ship-out from Iran of enriched uranium will, in fact, ensure that the break-out time for the Iranians will not be less than one year. Either this combination adds up or it does not, but there should be an explicit answer to Netanyahu's charge that Iran will be able to break-out much more quickly."
