Elizabeth Drew writes: Ever since Hurricane Bibi blew through Washington last week, advocates and opponents of a possible nuclear agreement with Iran have been assessing the damage. It’s clear that the traditional bipartisan approach toward Israel has been smashed. But the essential question is what effect Netanyahu’s visit will have on the the nuclear deal and above all, whether Congress, by bringing it to a direct vote as it now threatens, will reject it, thus ending a long effort to rein in Iran’s nuclear ambitions and raising a long-term question as to whether US negotiators’ word amounts to anything.

What this is really about is whether Congress will have veto power over the agreement itself—a power that has become Netanyahu’s and other opponents’ chosen route for sinking a deal.

Hours after Netanyahu’s speech, Senate Majority Leader Mitch McConnell, apparently eager to capitalize on its rapturous reception by the mostly Republican audience, announced that he’d shortly move that the Senate immediately take up a resolution requiring a congressional vote on any agreement with Iran. This went against McConnell’s earlier pledge that the Senate would proceed according to the “regular order,” which would have meant that legislation had to be considered by the relevant committee, in this case Foreign Relations, before it could be brought to the floor; and two days later, he backed down after Democrats threatened to block the move. But this is most likely a temporary retreat on McConnell’s part. [Continue reading…]
