Pakistan and India reciprocate covert attacks against each other because of years of animosity between the two countries.
Main reason is Kashmir, to be specific, Maqboza Kashmir or the Indian Occupied Kashmir.
India showed willingness to discuss and resolve the Kashmir issue after Kashmiri Mujahideens became a real threat to the Indian Army in Indian Occupied Kashmir.
President Musharraf offered them a breather in Indian Occupied Kashmir while the talks were going on but now India is back on her old rhetoric that Indian Occupied Kashmir is part of India.
To solve the Kashmir issue and to give some relief to US and NATO in Afghanistan, I would suggest 'guiding' the Talibans to the Indian Occupied Kashmir.
This will be a welcome move by the people of Indian Occupied Kashmir, US/NATO and Afghanistan.
Imagine a situation where Talibans are fighting along the Mujahideens in the Indian Occupied Kashmir giving peace at our Western borders, peace in Afghanistan and Kashimiris would also get their their rights.
