Its impossible for Pakistan to not care whats happening in Indian Occupied Kashmir, especially when Indians are building dams to block the water from naturally flowing through the Indus River into Pakistan.
There is a lot of mistrust thats why Kashmiris themselves should be in full control over their resources, and let the river flow as the Creator made it.
I understand your stance, but we need to work for a solution here. and all of us need to be flexible in our approach, for that to happen we need to work out other issues that can be worked out. if we are stuck with kashmir then there wont be any improvement unless you expect either pakistan or india to surrender to the other.
about rivers, well we can deal with it without bringing the whole complexities involved in it.
when I say, we try hands off approach, I mean that we should not try to destabilize each other and work in tandem at international level to get our national objectives and stem out terrorism. surely this much is possible for both countries.
if there is a will, there is a way......
