@farmboy He should be down to just the tank in India which can’t step out before getting hit in Persia. I am not that worried that he will build up enough forces in India to threaten the Middle East, unless he completely abandons the Pacific. UK can build 6 units/turn in the Middle East, with Japan only producing 3 to fight against them. China will be up to 23 units, including 4 art. He won’t be able to stand in front of that Juggernaut until late game.
Honestly, Japan isn’t doing as well as many OOB games. Russia can swing around with 8 Infantry and retake Kansu, ensuring that Japan’s northern forces don’t enter into Siberia. I think that his units will get crushed between the Chinese heading North and the Russians heading East. The bigger issue is how many Russian forces we lost killing the German unit in Karelia.
I would not want him to have 5 loaded transports + massive airforce that are free to do anything this round. He could claim Celebes and threaten to make a mess out of the Pacific.
