Walt and Mearsheimer redux

People are all excited that Walt and Mearsheimer are coming out with their book expanding on their paper last year about how nefarious the Israel Lobby is and how the United States would be better off if we just stopped all support for Israel.

Since their arguments have not become less idiotic over the past year, I see no reason for the counterarguments to have changed either. I discussed the kerfuffle last year here and here.
