It is stupid to compare this with Kashmir lol.
1)Firstly the king singned the instrument of accession, handing over JK to us.
2) For the referendum to occur Pak will have to withdraw troops completely, after which we can decide to hold one if we wish.
3)Demographics have changed considerably, extremists muslims there have killed made people flee the region, paks have been settling outsiders in their side. So at this point a referendum would be completely silly as none of the original conditions exist.
Garbage, most of them would rather stay with India, even some of the separatist factions at best want to be independant, Do you even know what the demographics?of JK or what the major regions are?
