I don’t know if you are Pakistani or not but they claim none of Kashmir or Jammu or Ladakh. They claim that it should be an independent country. They just shelter “freedom fighters” who are militants/terrorists in the region. And since religion plays a big role in their claim, demography of the region is damn important. Also Jammu and Ladakh aren’t the areas where Indian govt rules with such a heavy hand as they do in Kashmir.
At least read the link you are sharing my man. Also Wikipedia doesn’t provide enough context for you to understand the conflict.
