In my opinion , India did a right thing by liberating Bangladesh from the attrocities being carried out by Pakistan.It also seemed like a strategic move militarily , with our eastern border free of Pakistani threat.Had we let things go on , it would have brought in hordes of unwanted refugees into India and would have continually destabilized the subcontinent.
I feel India is going soft on its neighbours.We should continually use a carrot and stick approach to check our neighbours , which are more or less all failed states.We must play the role of big brother and keep these countries from falling into anarchy and civil war.
