Hey leave the US/NATO out of it. They are outsiders and will soon leave. The fact is that Pakistan and India have to coexist as neighbours. India does not want war. War with India is not in Pakistan's best interests and surely Pakistanis too don't want war. What then are the circumstances that may lead to war despite neither country wanting war? The answer is there for all to see. It is these misguided guided missiles called jihadis or terrorists who reside in Pakistan, they 'eat your salt' (to use a common idiom), kill and maim Pakistanis by the hundreds almost everyday and they, every once in a while also conduct adventure activities in India. They kill and maim Indians by the hundreds. To this end, they take the help of certain like minded Indians, even though, the planners, masterminds and the financiers are all Pakistanis. This is the single most inflammable factor which can cause war between the two countries. The Pakistani governmental agencies (and in this I include the Army as armies are organs of the government) have to simply win this internal war against the terrorists. If the common Pakistani does not want war with India, then the government elected by the common Pakistani will not want war. If the Pakistani government wins the war against the terrorists and subdues them, then possibilities of another Indo-Pak war in the future will recede and both countries can get on with the job of nation building and pulling our millions out of poverty.
That is the only lasting solution. This business of threatening to pull out XI Corps (7 and 9 Infantry Divisions) from Waziristan and sending them to the east and causing the Americans to panic and convince the Indians to back off as otherwise the WOT will suffer can not go on indefinitely.
