See my post above. It's fair to say that you won;t get an unbiased view of Finklestein from reading Derschowitz. Finklestein DESTROYED Derschowitx publicly in a famous debate that Dersch is still trying to recover from.
It is puzzling to me that people who would, presumably, leap at the chance to attack Ward Churchill have come to the defense of Norman Finklestein. Those two are cut from the same cloth.
