If Japan DOW on round 1 they will not be able to take India until round 4 or later. They will have a difficult time taking India on round 4 unless Japan buys 3 fighters on round 3 in FIC. So if they are in position to get 98% or greater on India turn 4 do you retreat the Indians? Japan needs their air force to take India but can they keep India once they take it if India retreated. Those planes will have to move back to the fleet if USA has a comparable force in Queensland on Turn 5 or later.
Blocking Japan from India/Australia if they DOW turn 1. (Assume no units at Caroline and bulk of fleet in Philippines)
