Pool is able to give us a compelling report about who really financed the Nazi-party and why Hitler had friends in high places, and that despite the fact that many first hand historical documents disappeared.
First, there was the fear for communism (Fritz Thyssen, Henri Deterding of Royal Dutch, Norman Montagu of the Bank of England ...). These people supported Hitler's party to win the working class and the ruined lower middle class away from communism.
Secondly, his anti-semitism (Henry Ford). Third, his racist/nationalist stance (the secret Thule society: a group of lawyers, judges, professors, policemen, aristocrats, scientists and businessmen). Fourth, friendly régimes (Mussolini).
And last but not least, the donations of his party members and his daily newspaper (a milk cow).
Pool gives us a penetrating picture of the political/economical situation in Germany after the First World War: the unbearable Versailles Treaty, the poverty, the unemployment, the hopeless division of the political parties and the plotting of von Papen and his backers, who supported Hitler when his party was losing support, for fear that his followers would jump over to the communists. Von Papen thought that after the elections, he would easily get rid of Hitler, a terrible mistake.
Pool convinced me of the ease with which money can subvert the democratic process.
One of the more controversial statements in this book is the reason of the abdication of King Edward VIII of England: not because of Mrs. Simpson, but because of his pro-Nazi attitude. This statement needed more underpinning.
