Bradley W. Hart concludes the story of would-be "American Hitler," Fritz Julius Kuhn, the German-American Bund, and the Jewish plumber Isadore Greenbaum.  Along with contributors, Arnie Bernstein and Greenbaum's grandson Brett Siciliano, Hart recounts the critical moment Isadore confronts the fascist Kuhn in Madison Square Garden... and how both of their lives were forever changed from that day forward.
