Deslee Campbell's handbook to understanding denial of the Holocaust over the past decades is very timely as right-wing extremism is gaining traction in Europe, especially in Germany, now that memories are fading and all living witnesses to Nazi deeds are passing from this earth, leaving only child-survivors. Dr Campbell is uniquely placed to present this material, being a trained historian and having studied the subject at Yad Vashem in Jerusalem and the Hebrew University of Jerusalem.
