The problem with an IC in India is that when Japan takes it, they can produce all that much more on the mainland.
Besides, I like to use the Indian forces to reinforce China. Japan has to either attack it, or go around and take that much longer to get to Moscow.
And, should Yakut SSR fall, Russian forces can move to Even and China forces can move to Novo creating a second wall. (Make sure to move US forces first, obviously, so that UK and Russian forces can move before Japan can attack.)
