I think this is an oversight. It seems to me IRL if Socotra was seized, India would have been deemed in mortal danger even if no Indian territory had yet been invaded.
If you wake up in your own bedroom to find a neighbor standing over you with a butcher knife at the ready, you know what's going on even if you're not bleeding yet.
I'm not so sure. From my limited reading on the place it appears that the Sultan was in charge from the mid-19th C. onward, and there was only a fairly minor RAF base there in WWII. The harbor is poor.
Based on your argument, why wouldn't an assault on DG trigger reinforcments? DG somewhat straddles the CT routes. Or, more to the point, how about Madras or Calcutta actually FALLING? That would be a body-blow to the industrial might of India, far in excess of any usefulness found at Socotra.
In the game Socotra is useful only because of the artifice of the off-map system. It can be used for naval search of the wormhole exits. But IRL, if the Japanese had gotten that far north, I doubt they would have wasted even a bomb on Socotra. They would have kept going and smeared the oil fields, and possibly tried to sink hulks to block the Suez Canal exits.
