Very interesting part of the book is when New York Jews, joined by American League of Labor, have a mock trial, and condemn Hitler. Hitler and the Nazis do everything they can to stop the trial, and think FDR can order people not to do things.
Later in the same chapter, everyone wants FDR to openly, instead of the heavy diplomatic efforts, condemn Germany's treatment of Jews. They are too worried though, how it will look when Hitler points out that in America we were lynching blacks and treating them very poorly. Some Jewish groups also worry that to anger Hitler, would only increase his attacks on Jews, ( this was in 1934). America was also worried about Germany reneging on big debts they owed us.
