US anyway can say what it likes. The dispute is bi-lateral and that's how its going to be solved.
The slow process of declaration of P-occup-K as part of Pakistan has started. Once this is done, the plebiscite is out of the window. This is what the Indian establishment and hence the foreign office is waiting for. The issue is practically dead after this. The LoC will become the IB. Then what will remain is purely Siachen.
But, this will cause tremendous internal upheavels, because this is not a tactical withdrawal, but, a strategic change in state policy. How will the internal stakeholders, (the PA may be in sync, but the rest??) respond to a proposal like this? How to control the fallout if they decide to create a problem?
Somehow, I thinkk, the PA is realising there are more priorities in the western front and it needs peace on the eastern front for this. Also, rationalisation that the insurgency has back fired with the internal state of Pakistan, including ordinary people being effected by this.
It is in the best interests that, we hail the declaration of P-occu-Kashmir as a part of Pakistan. Peace, finally in South Asia, will seem achievable.
