Yes, but arent Azad Kashmir and the Valley now the main areas of contention? As far as I know, Jammu and Ladhk are content to be Indian, while Northern areas are content to remain Pakistanis, although they would have to be turned into a province officially.
Although even in Azad Kashmir there is a large number of people who would prefer to remain Pakistani or become Pakistani depending on how you look at it.
My point was regarding ethnicity...in terms of ethnicity and culture, it is incorrect to lump Azad Kashmir together with Kashmir. It would technically be more correct to refer to the area as Azad Jammu or something along those lines (the official name is Azad Jammu & Kashmir).
In any case, I don't think anyone has ever specifically asked the people of Azad Kashmir what they want. However, judging from the fact that there hasn't been any major anti-Pakistan uprising in the area, and the fact that it is one of the biggest recruitment grounds for the Pakistani military, it would seem that the people are relatively happy remaining in Pakistan.
I think the only major area of contention at this point is Kashmir and a few adjacent areas in Jammu where Kashmiris have traditionally formed the majority of the population.
