They would do well to read William Shirer's The Rise and Fall of the Third Reich instead.
Absolutely.
Perhaps they are like William Shirer in 1936 when he wrote a report on a Hitler Speech. In the speech Hitler said he was going to kill all the Jews and conquer europe for Germany. Shirer reported what hitler said, then added. That Hitler was just playing to his base. The question Shirer wanted answered was what were Hitler's real intentions.
