Propaganda? Did you read the book? Read the book not what others say about this book.
Hitler would be a socialist, maybe even a communist. He hated what his father did for a living. He was not a very bright anarchist, a very religious man, and foremost a nationalist; from the get-go....
Calling Hitler a very religious man is oversimplification. Hitler was a pantheist.
Adolf Hitler Was Neither Christian Nor Atheist

Hitler repeatedly affirmed the existence of God, but his conception of God differed substantially from the Bible’s. He rejected Christ’s divinity and frequently mocked Christianity. Hitler, Weikart points out, was a baptized, confirmed Catholic raised in Austria, a predominantly Catholic country, and he retained some vestiges of Christianity. Nevertheless, he repeatedly repudiated Christianity (especially privately) as “a Jewish plot to undermine the heroic ideals of the Aryan-dominated Roman Empire.” Hitler denounced Christianity as a poison, outmoded and dying, ridiculed its teachings, and persecuted Protestant and Catholic churches alike during the Third Reich [in cases when they refused to do his bidding]. Nor was Hitler an occultist, [as some have claimed], since he explicitly repudiated key occult convictions and mystical practices.
Weikart argues that Hitler is best understood as a pantheist, one who believes that nature is God and that the cosmos provides principles to guide human conduct. He frequently deified nature, referring to it as eternal and all powerful. . . . While presenting God as the creator and sustainer of the Volk—the German people—Hitler and the Nazis used religious symbols, terms, and passion in their speeches, rallies, and ceremonies to create an alternative faith. Hitler fully expected the Nazi worldview to replace Christianity in Germany and transform its culture and life. Moreover, Nazi propaganda depicted Hitler [himself] as a messianic figure, a savior chosen by God to liberate Germany from the punitive Versailles Treaty and restore its power and place in the world.
Most people do not realize how fortunate humanity was that WWII ended as quickly as it did and that the Nazi ideology was crushed. The ideal timing of the US entry into the war. The fortuitous and and worst recorded winter in modern history and the fact that Nazi foreign intelligence service the Abwehr was led by Wilhelm Canaris actively worked against a Nazi victory were all critical. The tremendous role played by Canaris in ensuring Nazi defeat cannot be understated and to the day is largely shrouded in mystery and not publicly released. Despite that the Nazi were very close to an early victory as the following video demonstrates in stark terms.
