Propaganda, Adolf Hitler wrote in 1924, is a truly terrible weapon in the hands of an expert. State of Deception: The Power of Nazi Propaganda documents how, in the 1920s and 1930s, the Nazi Party used posters, newspapers, rallies, and the new technologies of radio and film to sway millions with its vision for a new Germany-reinforced by fear-mongering images of state enemies. These images promoted indifference toward the suffering of neighbors, disguised the regime's genocidal actions, and insidiously incited ordinary people to carry out or tolerate mass violence.The United States Holocaust Memorial Museum is addressing this topic today because, in an age of instant electronic communication, disseminators of messages and images of intolerance and hate have new tools, while at the same time consumers seem less able to cope with the vast amounts of unmediated information bombarding them daily. It is hoped that a deeper understanding of the complexities of the past may help us respond more effectively to today's propaganda campaigns and biased messages.
