It is simple. The more India forces Kashmir, the more Kashmir clings to Pakistan. I am from Kashmir.
If there is anything i have learnt that coercion is not long term solution. The relationship of Pakistan and Bangladesh didn't work in the past, but relationship of Kashmir and Pakistan is very strong, and so is Kashmir love for Pakistan. In fact, Pakistan Occupied Kashmir is relatively safe; however, what is happening in Indian Occupied Kashmir doesn't reassure people in Indian Occupied Kashmir at all.
In short, Kashmir heart already belongs to Pakistan. It is matter of time before Kashmir becomes part of Pakistan because it wants to be part of Pakistan. That is the beauty. No coercion is necessary.
