Why would we do that again? All the states of Balochistan already acceded to Pakistan in late 40's early 50's so why should Pakistan do that again for lungi land.
Chittagong never had chance to decide. So freedom for Chittagong Buddhist from dhaka oppression.
There is an active liberation movement in Baluchistan hence Baluch people deserve their right of self-determination, while there's no such thing in Chittagong. Heck Chittagong was the area where the proclamation of Bangladesh's independence was made and the first resistance against the Pakistani forces took place.
Buddhists in Chittagong number around 5% of the population, not that they are seeking any secession.
