The powerful Israel lobby has been badly damaged, and that's good news for both Palestinians and Israelis.
It is hard to exaggerate the damage inflicted on AIPAC by the congressional defeat of its efforts to torpedo the Iran nuclear deal. It is not as if AIPAC won't live to fight again, because it will, but this defeat has ruptured the status quo, possibly forever.
The extent of its efforts to defeat the deal was unprecedented even for a lobby known for its no-holds-barred wars against past White House initiatives it considered unfriendly to Israel, going all the way back to the Ford administration. AIPAC, and its cutout Citizens For A Nuclear Free Iran, reportedly budgeted upwards of $20 million for a campaign that included flooding the airwaves with television spots; buying full-page newspaper ads, arranging fly-ins of AIPAC members to Washington, organizing demonstrations at offices of AIPAC-friendly members of Congress who were believed to be wavering, and ensuring that problematic legislators were officially warned by precisely the right donor.
