In January 1941, Hitler asks the Japanese if they want to participate in his operation "Barbarossa". He offers them the whole east of the Soviet-Union, while the Reich would take the west of the Soviet-Union. Because the ressource-problems of Japan would be solved after acquiring the east of the SU, Japan accepts the offer and prepares for an invasion of the east of the SU.
Operation Barbarossa starts at 22. June 1941. The German army+client states attack the west of the SU, the Japanese army attacks the east of the SU. Japan will NOT attack the USA while it is fighting a war against the SU (So Pearl Harbour won`t happen).
What do you think will happen? How will the US react? Will the axis win the war?
