Japan is another story. With the arrival of US air units the battle is probably lost and we will have to go on the defensive. In addition we have absolutely no idea where the US fleet is.
Another year and time to look at our situation. Germany has 1241 income! More than the US (probably). A real giant. Personally I feel this is way too much, no matter how well Germany is doing.
A major US fleet with at least 2 carriers is confirmed near Madagascar. We are doing what we can to delay them, including a diversionary/suicidal landing.
To help their struggling allies, Germany sends an army group to attack India from the west. An Indian army in Mashhad is destroyed without German losses.
The IJN launches a diversionary attack on Darwin. We have no real intention to attack Australia. The fleet will be sent west to hopefully catch the US fleet unawares.
As a massive US air raid eliminates the lone Japanese fighter unit, Germany liberates Afghanistan. Japan starts a massive AA upgrade program for all its units.
