I came across the Mein Kampf article in the Wikipedia. The horror and weirdness of his antisemitism aside, what is remarkable is how well he described his war strategy, how his plan was laid out so ahead of its execution a decade later. How nobody seemed to believe him until he actually implemented it.
Hitler predicts the stages of Germany’s political emergence on the world scene: in the first stage, Germany would, through a program of massive re-armament, overthrow the shackles of the Treaty of Versailles and form alliances with the British Empire and Fascist Italy. The second stage would feature wars against France and her allies in Eastern Europe by the combined forces of Germany, Britain and Italy. The third and final stage would be a war to destroy what Hitler saw as the “Judeo-Bolshevik” regime in the Soviet Union that would give Germany the necessary Lebensraum (literally “living space”).
