Hitler and the Nazis used propaganda to influence people in almost every imaginable way. While every politician uses propaganda to some extent, the Nazis, seeking to establish a totalitarian state, besieged the German people with propaganda on an unprecedented level. Like Franklin Roosevelt in the United States, Hitler used the radio to reach into the living rooms of German people through frequent speeches and addresses. Unlike Roosevelt, however, Hitler peppered his speeches with hateful messages, playing to German fears and anxieties about the times in which they lived, and blaming all of the problems confronting Germany on Communists and, above all, Jews, who Hitler portrayed as traitors, racially inferior, and existential threats to the German people. Films commissioned by the Nazis drove home the same message, as did textbooks that were deliberately written by Nazi propagandists to drive home German racial theory. The Nazis also commissioned grand public spectacles intended to impress the popularity of their movement on the German people. The annual Party rallies at Nuremberg, documented by Leni Riefenstahl's film Triumph of the Will, for example, featured hundreds of thousands of uniformed Party members engaged in parades, reviews, and other public demonstrations. These helped create the impression that the Nazi Party represented an unstoppable movement of the people. Above all, the Nazis, particularly propaganda minister Joseph Goebbels, depicted the German people as unified in the face of external and internal threats, and Adolf Hitler was the living embodiment of what the Nazis called the Volk.
