You might be able to fly some US fighters to India via sub-Sahara Africa to India. If Japan cannot get India until J5, they may get there in time to save India.
Also, on turn 2 maybe the French fighter can start flying to Moscow from Scotland, than maybe get to India in time to help defend it. Or have it fly on turn 1 to sub-Sahara Africa route.
This is not a winning solution but it might buy some time.
