What are the motifs in Adolf Hitler by John Toland?

A recurring idea in this book is banality of evil. Hitler copies the slogans of the right-wing of his day in Germany and turns them into the most extreme version. Instead of restricting Jews and blaming them for various misdeeds, he wants to kill them all. Instead of complaining about a difficult economic situation, Hitler wants to invade neighboring nations and seize their land and wealth. Many people and even nations want to find an easy way out of their economic problems, but Hitler makes a case for the extreme action to solve Germany's problems through war.
