All India!!! banzai!!!
Seriously, I think everything is possible, even India. Like China, it depends on how far forward your opponent defends. India div's, like china, start with low morale and exp. They need time to gain both. Once they, their numbers are sufficient to crush the empire. Catch is if they defend too far forward, then IJ can route them and keep them going.
How far forward is too far? Hard to say. I feel that IF IJ is pushing for India from the start, then Calcutta might very well be too far foward. If so, this is your woindow of opportunity. Most allied players start to defend India at Calcutta. So, if you route them at Calcutta, the rest of hte country is open. Several have speculated that a end run to Karachi, and then a mop-up in central india is the best strategy. be interesting to see what you do.
