Israel’s first course of action looks to be an intense lobbying effort in the US Congress to oppose the deal. Netanyahu spoke against the emerging deal before a joint session of Congress in March. Yet despite strong support among Republicans in Congress, there is little that can be done now.
The Senate can weigh in on the agreement but can’t kill it, because Obama doesn’t need congressional approval for a multinational deal that is not designated a treaty.
Lawmakers have 60 days to review the agreement, during which Obama can’t ease penalties on Iran. Only if lawmakers were to build a veto-proof majority behind new legislation enacting new sanctions or preventing Obama from suspending existing ones, the administration would be prevented from living up to the accord.
