Dear Sanjay Joshi , why don't see the brighter side of that episode? We have got rid of considerable number of fanatic muslims in the process and also created a buffer state between Afgasthan and India. Had there been no country called Pakistan in between, we would have been the target to Taliban problems and its aftermath in Afganisthan!
As Lord Krishna said in Gita, whatever happened was for good and whatever is going to happen is also for good!
