To be perfectly blunt: that... won't be happening. Even if we somehow managed to pull off Karachi this turn (and I assure you, the odds of that are rather low), we're not trying to take all of India, because that would be a terrible idea for numerous reasons. As such, the Bannerjees will be getting our various agricultural research -- but, again, that doesn't hugely matter to us, since it's mainly civilian uses, and even stuff like tarberries which do have military uses aren't nearly useful enough to be worth not getting his bonus.
