“It Can’t Happen Here” is a semi-satirical political novel published during the rise of fascism in Europe. The novel describes the rise of Berzelius “Buzz” Windrip, a politician who defeats favored Franklin Delano Roosevelt for President of the United States, after fomenting fear and promising drastic economic and social reforms while promoting a return to patriotism and “traditional American values.” After his election, Windrip takes complete control of government and imposes totalitarian rule with the help of a ruthless paramilitary force in the manner of Adolf Hitler’s SS troops.
The novel's subplot centers on journalist Doremus Jessup's opposition to the new regime and his subsequent struggle against it as part of a liberal rebellion. Reviewers at the time emphasized the connection with Louisiana politician Huey Long (1893 – 1935) who was preparing to run for president (like George Wallace did years later) in 1936 when he was assassinated in 1935 prior to the novel’s publication.
I have a complete library on Adolf Hitler with more than two score of books on all aspects of his life, books that I have read assiduously, and the same goes for two biographies on Albert Speer, as well as his autobiography. Speer was as slippery a character as Hitler was demonic, and as you have pointed out, avoided being hanged at Nuremberg for his distracting finesse.
