There were numerous reasons that Stephen Walt and John Mearsheimer were accused in prominent venues of all sorts of crimes -- including anti-Semitism -- when they published The Israel Lobby, but the most common cause was the book's central theme: that there is a very powerful lobby in the U.S. which is principally devoted to Israel and causes U.S. political leaders to act to advance the interests of this foreign nation over their own. In The New York Times today, Tom Friedman -- long one of Israel's most stalwart American supporters -- wrote the following as the second paragraph of his column, warning that the U.S. was about to incur massive damage in order to block Palestinian statehood:
This has also left the U.S. government fed up with Israel's leadership but a hostage to its ineptitude, because the powerful pro-Israel lobby in an election season can force the administration to defend Israel at the U.N., even when it knows Israel is pursuing policies not in its own interest or America's.
. . .
Is that not exactly the point which The New York Times' most "pro-Israel" columnist himself just voiced today? This thesis has long been self-evidently true. Indeed, many of the same Israel-loyal neoconservatives who accused Walt and Mearsheimer of promoting an anti-Semitic trope of "dual loyalty" -- by daring to suggest that some American Jews cast votes based on what's best for Israel rather than the U.S. -- themselves will explicitly urge American Jews to vote Republican instead of Democrat because of the former's supposedly greater support for Israel (you're allowed to argue that American Jews should make political choices based on Israel but you're not allowed to point out that some do so). Ed Koch just ran around the 9th Congressional District in New York successfully urging American Jews to vote for the GOP candidate based on exactly that appeal ("Koch, a Democrat, endorsed in July as a way to 'send a message' to Obama on his policies toward Israel").
