So, whatever you do on the Pacific side of the board really makes no difference. Obviously, since you are throwing everything, including the kitchen sink at Japan, Japan will not be able to get anywhere. However, the Axis is going to win easily on the Europe side of the board. With so much committed against Japan Italy is going to make life tough for UK in the Med which means little to no help is coming from UK to Moscow and since you have drawn off so many Russian resources to go against Japan Germany is going to steamroll Moscow.
That being said attached would be my J2 response to your Allied opener. This protects Korea and SZ6 from Russia and the US and stalemates China temporarily. Japan, amazingly, will take Sydney on J3; I actually did not think that was possible. Then with ANZAC out of the game they will be able to turn against the separated smaller US fleet and UK fleets and try and hold on as long as possible forcing the US to continue spending resources in the Pacific while the game is lost for the Allies on on the Europe side of the board.
