I couldn't find an appropriate existing thread for this, so I'll post it and let the "powers that be" move it if needed. It entails the launching of Barbarossa, and Hitler's past statements concerning world domination. It also blends in the awkward position Hitler put his nominal "allies", the Japanese into. From Time magazines of June, 1941. For what Adolf Hitler did this week, and what he hopes to do in the future, had been told to Hermann Rauschning in 1934 and published by him in 1939. Said Hitler then: Perhaps I shall not be able to avoid an alliance with Russia. I shall keep that as a trump card. Perhaps it will be the decisive gamble of my life. . . . But it will never stop me from firmly retracing my steps and attacking Russia when my aims in the West have been achieved. . . . We must win the victory of German race-consciousness over the masses eternally fated to serve and obey. We alone can conquer the great continental space, and it will be done by us alone, not through a pact with Moscow. We shall take this struggle upon us. It will open to us the door to permanent mastery of the world. (emphasis mine) From a Time magazine article of June 30th, 1941 (p.2): Germany: World or Ruin - TIME Who says Hitler didn’t have designs on world conquest! What does mastery mean if not that? This launching of Barbarossa put his nominal ally Japan into a bad position, they had been mauled by the Red Army and General Zhukov on two occasions in the recent past, and had decided to follow Hitler’s lead and sign a "non-aggression" pact with the Soviets. Japan’s dilemma as to "aiding Germany by attacking the Soviet Union" when Barbarossa developed was this. When the Russo-German war actually came, doomed country or not, Japan was forced to face the fact that her ambiguous diplomacy had put her on an ambiguous spot. By the Tripartite Pact she was bound to go to Germany's assistance, if Germany were attacked. (emphasis mine) By the neutrality agreement with Moscow, she must remain neutral if Russia were attacked.(emphasis mine) So she remained neutral, as Germany was the aggressor—an ugly thing for a nation to admit about its friend in public.
