I have seen mentioned in a couple of threads, that if there were no German invasion of the Soviet Union, that Japan would not attack the British/Dutch/USA in the Pacific. (The risk of a undistracted Soviet Union attacking Japan being too great).
Is this a true thing? It seems the advantages of Germany focusing on Britain would outweigh the risk of a Soviet attack (it is already a high risk situation anyway that Japan put itself in). (There is also the possibility of direct German-Japanese trade across the Trans-Siberian.)
