It's easy to look back and realize what a jerk Hitler was. But at the time, Hitler looked pretty good to the German people, with the help of the media. He was TIME Magazine's Man Of The Year in 1938. The German people assumed they were safe from a tyrant. They lived in a Republic, after all, with strict laws regarding what the government could and more importantly could not do. Their leader was a devoutly religious man, and had even sung with the boy's choir of a monastery in his youth.
The reality was that the German people, as individuals, had lost their courage. The German government preferred it that way as a fearful people are easier to rule than a courageous one. But the German people didn't wish to lose their self-image of courage. So, when confronted with a situation demanding individual courage, in the form of a government gone wrong, the German people simply pretended that the situation did not exist. And in that simple self-deception lay the ruin of an entire nation and the coming of the second World War.
