Reviving a debate that had grown quiescent, C-SPAN offered airtime to John Mearshimer and Steven Walt, authors of the infamous “Israel Lobby” paper that received any number of well-deserved slams upon publication back in March ( here is the New York Sun’s concise riposte). The two have ducked debate with Alan Dershowitz and other critics. Yesterday, C-SPAN offered a platform to Anti-Defamation League president Abraham Foxman. It would be difficult to overstate how terrible a job he did. Ostensibly invited to rebut the Walt/Mearshimer thesis, Foxman actually offered it more free advertising by simply repeating the claims in the paper and then denouncing these assertions as obviously anti-Semitic. Well, they may be, but viewers would first, it seems to me, want to know: Are they true?  Foxman never contradicted a single point, not cited any examples of the scores of misrepresentations, omissions, and slanders in the paper. The persistence of American support for Israel — despite such feeble advocates as Mr. Foxman — is yet further evidence that the fantasy of an all-powerful Jewish lobby cleverly dominating the debate in America is risible.
