Hmm, at least you kept it balanced, I am just tired protecting my country's national integrity from the Bangladeshi aggression in PDF.
Just for the sake of argument, "Greater Bangladesh", as proposed by the BD members here, will be a result of religious intolerance and blatant communalism, we by no means will let our country break and our people losing their homes, again. We have come a long way from the days of freedom struggle and independence and partition, and we are not so vulnerable anymore.
And for the "Akhand Bharat", that can only become possible when the only reason for partition, religion, becomes an obsolete reason to keep people separated, such things happen when the society becomes very educated and very liberal, that will eventually happen in the subcontinent, but by that time people will develop a much more stronger sense of nationalism and sovereignty, so what has happened won't be undone.
