Why do you think USSR would have helped Pakistan, a great aid giver and friend to India in fifties, sixties, seventies and eighties and even now? Pakistan and India have been arch rivals had three wars in the past on issue of Kashmir. I think you know that. Will India a great ally of Russia would have allowed Russians to give aid to Pakistan? I think now Russia itself receive aid from Uncle Sam for rebuilding and switching over to market economy?
It is now Russia, no more USSR after its disintegration in the nineties. You kept on writing USSR.
