I think the decision was right at that time and the Indian Army did well as it always has. What is wrong with the Indian way is its politics with no vision for the future and the way they should modify the present to get a better future for the country. All decisions even now in foreign policy are taken with a knee jerk reaction with no idea of whats going to happen in the future.
We should have maintained enough influence in Bangladeshi politics, development and economics...which is what would have helped the relation between the two countries. We are doing the same in Nepal and in Tibet....with no vision of future security or relation. I hope we realise it before its too late in all cases and we are surrounded all over with a very hostile neighbourhood.
