I am sorry mate. Balochistan is not the case of similar proportion.
Pakistan Tried it in Bangladesh and if you want to end up like us in 1971 you are welcome.
I am not arguing for Baluchistan if that is what you want Argument for the sake of argument. There is no mass public supported Freedom movement in Baluchistan like their is in Kashmir and was in Bangladesh in 1971. Balochistan is almost 1/3rd of Pakistan total Land area and its population is just 12 Million, Almost Equal to Lahore city. Yes Total Balochistan population is approximate to Lahore city.and of that population only 54% are ethnic Baloch. Rest 46% are Pakhtuuns, Sindhis, Saraikis and Punjabis None of Whom have any interest in Baloch cause. Plus their are more ethnic Baloch living in Punjab Province then in Baluchistan. Plus Plus Plus out of the small Ethnic Baluchis living in Baluchistan their are only marginal number who want to be Independence all of their leaders enjoy lavish lives in Switzerland. Only a Fool will believe in Baloch story.
We have 100 times more trouble in Tribal Areas then in Baluchistan , and nobody wants freedom in Tribal Areas.
And Sri Lanka is an Island, And the Tamils had no Sizeable Support, Sri lanka had no Foe that can support Tamil Cause. Infact Both Pakistan and India Tried to help Sri lanka.
Unfortunately your Kashmir Ambitions are not Blessed with Supportive Neighbors like Pakistan and India in Tamil Cause. Neither is Kashmir an Isolated Island.
