Hitler in the context of his times.

Although Adolph Hitler pursued an aggressive war policy against European regimes, many European states were no less racist or imperialist in their own way of thinking.  In devastating Europe's industrial infrastructure and dampening her appetite for war in general,  the Third Reich forced Europe to reconsider her colonial conquests on the African continent. One can fairly consider that the liberation granted and wars of liberation fought and won against European colonial overlords, whether German, Belgian, French, Portuguese or of the British Empire and, the freedoms won, were in part beneficial byproducts of WWII.
