Here is John Mearsheimer, writing last year on the Foreign Policy blog of his Israel Lobby co-author Stephen Walt, defending the positive blurb he provided for a new book by Hitler apologist and Holocaust revisionist Gilad Atzmon:
There is no question that [The Wandering Who?] is provocative, both in terms of its central argument and the overly hot language that Atzmon sometimes uses. But it is also filled with interesting insights that make the reader think long and hard about an important subject. Of course, I do not agree with everything that he says in the book — what blurber does? — but I found it thought provoking and likely to be of considerable interest to Jews and non-Jews, which is what I said in my brief comment.
Mearsheimer’s blurb read:
Gilad Atzmon has written a fascinating and provocative book on Jewish identity in the modern world. He shows how assimilation and liberalism are making it increasingly difficult for Jews in the Diaspora to maintain a powerful sense of their “Jewishness.” Panicked Jewish leaders, he argues, have turned to Zionism (blind loyalty to Israel) and scaremongering (the threat of another Holocaust) to keep the tribe united and distinct from the surrounding goyim. As Atzmon’s own case demonstrates, this strategy is not working and is causing many Jews great anguish. The Wandering Who? should be widely read by Jews and non-Jews alike.
