From Tony Judt in NYTimes:
"The damage that is done by America's fear of anti-Semitism when discussing Israel is threefold. It is bad for Jews: anti-Semitism is real enough (I know something about it, growing up Jewish in 1950's Britain), but for just that reason it should not be confused with political criticisms of Israel or its American supporters. It is bad for Israel: by guaranteeing it unconditional support, Americans encourage Israel to act heedless of consequences. The Israeli journalist Tom Segev described the Mearsheimer-Walt essay as "arrogant" but also acknowledged ruefully: "They are right. Had the United States saved Israel from itself, life today would be better ...the Israel Lobby in the United States harms Israel's true interests."
BUT above all, self-censorship is bad for the United States itself. Americans are denying themselves participation in a fast-moving international conversation. Daniel Levy (a former Israeli peace negotiator) wrote in Haaretz that the Mearsheimer-Walt essay should be a wake-up call, a reminder of the damage the Israel lobby is doing to both nations. But I would go further. I think this essay, by two "realist" political scientists with no interest whatsoever in the Palestinians, is a straw in the wind."Once again, thanks to Angry Arab.
