The racial struggle for space envisioned by Hitler was essentially unlimited, a policy that could only have two results: total defeat or total conquest. Hess discovered in 1927, while the two were imprisoned at Landsberg prison, that Hitler believed only one race with total hegemony could bring about world peace. Hitler confirmed this attitude, regarding Europe specifically, in August 1943 speaking to his naval advisors and declaring, "Only if all of Europe is united under a strong central power can there be any security for Europe from now on. Small sovereign states no longer have a right to exist". In "Mein Kampf", Hitler states his view that the total (but, as he saw it, temporary) destruction of civilization was, to him, an acceptable condition of final Aryan victory.
