Quote #4
Blood mixture and the resultant drop in the racial level is the sole cause of the dying out of old cultures; for men do not perish as a result of lost wars, but by the loss of that force of resistance which is continued only in pure blood. All who are not of good race in this world are chaff. (1.4.42)
Shirer quotes this passage verbatim from Mein Kampf, in an effort to illustrate both the historical inaccuracy of Hitler's views on human development as well as the deep-seated hatred that Hitler had for all those whom he excluded from his "master race."
Quote #5
To Hitler, as he had publicly declared a thousand times, the Jews were not Germans, and though he did not exterminate them at once (only a relative few—a few thousand, that is—were robbed, beaten or murdered during the first months), he issued laws excluding them from public service, the universities and the professions. And on April 1, 1933, he proclaimed a national boycott of Jewish shops. (3.7.80)
The robberies, beatings, and murders of a few thousand Jews in Germany in 1933 was a drop in the bucket compared to the millions who were massacred later. Hitler's policy was to gradually remove Jews from public life in Germany before settling on the "Final Solution." If you want to destroy a people, first you have to designate them as the "other."
Quote #6
Even one returning to Germany for the first time since the death of the Republic could see that, whatever his crimes against humanity, Hitler had unleashed a dynamic force of incalculable proportions, which had long been pent up in the German people. (3.7.201)
Here's a good example of how Shirer believed that Hitler was successful because Germans already believed much of what he was preaching based on their history of anti-Semitism and belief in German superiority.
