Premise: Even the title of Cohen's book and its cover art--a brass-knuckled fist--are lifted directly from a book published eight years ago, Paul Breines' Tough  Political Fantasies and the Moral Dilemma of American Jewry , which analyzes the psychological underpinnings of the cult of Jewish toughness born after Israel's victory in the 1967 Six Day War.
Hypothesis: On the cover of Cohen's book is a depiction of a brass-knuckled fist.
