Yes , but that does not invalidate what I am saying. He could criticize the Kayser in 1924 as that was history and he was right. But he made the same mistake in 1941 !
Hitler was not a fool and knew that Germany could not win a two front war. but, at the end of 1940, he was devoid of any strategic option, he needed the natural resources and petrol of Russia, and he dreamed of vital space for Germany, not forgetting his racism against Slaves.
