Rick Richman is the proprietor of Jewish current issues. He writes to advise that John Mearsheimer and Stephen Walt have reponded, sort of, to the critics of their “Israel Lobby” paper here in the letters column of the London Review of Books where the article version of their paper was originally published. The full pseudoscholarly version of the M-W paper is posted on the Kennedy School site.
Rick notes that University of Pennsylvania visiting scholar Jeff Weintraub (a “democratic socialist” and putative member of the “Israel Lobby” in M-W World) comments here on the M-W response. Weintraub finds the response “surprisingly thin” and observes that it fails to “offer any significant or convincing responses to the most serious criticisms of their analysis.” Rick himself comments on one strand of the M-W response here.
