I could only join again this late afternoon after yesterday's and today's connection problems.
And there is nothing particular to add; I can only confirm.
Yes, like Virginia, T(h)ink and Rooster, I suppose that Subhas Chandra Bose would have been used and abused by the Japanes, like many other "key puppets": manipulated and dumped (or rather eliminated), if they were of no use anymore. And, had the Japanese been victorious and had he been lucky enough to survive (physically and mentally) and escape from their control, he would have certainly tried to fight them from "the underground".
