Nonsense. Russians are far more pragmatic than you realise, as are Pakistanis. Interests have shifted. Most importantly, Russia is not USSR. If USA and Vietnam can be cordial, so can Russia and Pakistan.if that is true then Russians will have an ax to grind with Pakistan. Russians would surely be on the side of India and not be selling Pakistan any weapons. Might even stop selling weapons to China since China arms Pakistan.
That's beside the point of this thread though.
