Just today, Noam Chomsky compared the never Biden movement with the German communist party's policy against social fascism. Watch here. If we put the modern politics aside, is their a course of action that the party could have followed to prevent the rise of Hitler and what responsibility do they hold for that rise?
Addendum: I like to leave a further reading section and forgot to add it to the original comment. Fritz Stern: “Dreams and Delusions: the Drama of German History” Fritz Stern: “Five Germanys I have Known” Benjamin Carter Hett: “The Death of Democracy: Hitler's Rise to Power and the Downfall of the Weimar Republic”** **I am not a huge fan of this one as a scholar. It’s a little sloppy at times in the details but it paints the broad strokes vividly and is useful if read with a discerning and careful eye. Useful. But read carefully. Russel Lemons: „Hitler’s Rival: Ernst Thälmann in Myth and Memory“ a biography of the communist leader who opposed Hitler.
