First of all, there is no 'issue'. The state is occupied by radical arab wannabes who have cleansed the local population out. Not to mention the years of secret infiltration of pashtuns and others into Kashmir to change its demography. Thanks to secularism and its Hindu/Buddhist/Sikh hate, there are no indigenous people left there.
The decision is now in the hands of the new government on how to restore order and destroy the anti-national secular forces that have disturbed the years of peace in Kashmir we all have known from the era of Raj Kapoor.
Neither Pakistan nor US have anything to do with this.
