Although pursuing an alliance based on "Realpolitik" with Imperial Japan in the battle against the "Western Plutocracies" and Soviet Bolshevism, the Nazi leadership ultimately considered this cooperation only temporary in nature. The racial ideology of Nazism predicted that the fate of human civilization depended on the ultimate triumph of the Germanic-Nordic peoples, and in fact the populous Asian continent was seen as the greatest threat to hegemony of the white race. The Japanese people were characterized as 'culture-bearers', meaning they could make use of the technological and civilizational achievements of the Aryan race and by so doing maintain an advanced society, but could not truly create 'culture' themselves. Gerhard Weinberg asserts that the historical evidence points to the conclusion that Hitler, like he had done with the Soviets in the 1939–1941 period, employed a tactic of conceding to the Japanese whatever they desired until they in turn could be defeated in a subsequent war. In early 1942, Hitler is quoted saying to Ribbentrop: "We have to think in terms of centuries. Sooner or later there will have to be a showdown between the white and the yellow races."
