"Professor Walt's fellow Harvard professor Alan Dershowitz - criticised in the article as an "apologist" for Israel - denounced the authors as "liars" and "bigots" in the university newspaper, The Harvard Crimson, and compared their arguments to neo-Nazi literature....Prof Mearsheimer said the storm of protest proved one of its arguments - that the strength of the pro-Israel lobby stifled debate on US foreign policy. "We argued in the piece that the lobby goes to great lengths to silence criticism of Israeli policy as well as the US-Israeli relationship, and that its most effective weapon is the charge of anti-semitism," Prof Mearsheimer told The Guardian. "Thus, we expected to be called anti-semites, even though both of us are philo-semites and strongly support the existence of Israel.""
