At least when I was in grade school, we learned the very basics of how the Third Reich came to power in the early 1930s. Paramilitary gangs terrorizing the opposition, the incompetence and opportunism of German conservatives, the Reichstag Fire.
And we learned about the critical importance of propaganda, the deliberate misinforming of the public in order to sway opinions en masse and achieve popular support (or at least the appearance of it). While Minister of Propaganda Joseph Goebbels purged Jewish and leftist artists and writers, he built a massive media infrastructure that played, writes PBS, “probably the most important role in creating an atmosphere in Germany that made it possible for the Nazis to commit terrible atrocities against Jews, homosexuals, and other minorities.”How did the minority party of Hitler and Goebbels take over and break the will of the German people so thoroughly that they would allow and participate in mass murder? Post-war scholars of totalitarianism like Theodor Adorno and Hannah Arendt asked that question over and over, for several decades afterward
Saying something obviously untrue, and making your subordinates repeat it with a straight face in their own voice, is a particularly startling display of power over them.
