Well actually your description makes it even more similar.
Half of the population in J&K in pro Indian mainly in Jammu and Ladakh. The Gujjar and Bakerwall tribes are pro-Indian as well. Agreed that J&K percentage of landmass is smaller than Balochistan land mass in Pakistan but that is what makes the issue less severe. Similarly the population percentage affected is smaller for India as well. 5million/1.2 billion as compared to 5 million/180 million in Pakistan.
And while J&K has suffered from one insurgency mainly backed by Pakistan since 1990. Balochistan has sufferred from five insurgencies in the same period.
The issue is about Baloch sub-nationalism or Kashmiri sub-nationalism. And the best way to solve it is to give cultural autonomy within the ambit of the union. Ofcourse foreign interference will play a role in causing problems but barring that, this would be the best way to resolve issues.
