Thank you for all the advice. I do have a question about this though:@Caesar:
The real reason as I pointed out is that J1 can be used to get FIC under Japanese control so you can factory it on J2, and then proceed to mass whatever you need to take India so by the time US gets into the fight, Japan is much better in position in Asia.
Wouldn’t it be better to do a Calcutta crush and take India by J3 or J4 and then concentrate on America and ANZAC?
