strange T-Rex. i think you are from a non-military background so you are talking like this. i have a healthy respect for PA officers and take them as professionals.
Its not easy to use "nukes". Be rest assured, if there is a chance of confrontation, US, UK, France, Germany, Canada, Russia along with others and India will immediately ensure that the threats posed by them are removed in the earliest phases of war via SF missions and airstrikes at whatever the cost. Anyways US is in control of those now and they are under its threat forever. That is the condition for Pakistan being safe from direct US intervention yet.
Next, any use of nuclear warhead, even in tactical situation will call for massive retaliatory strike from India, and India has 80 times the industrial base than Pakistan not to mention the facilities. There is something known as the industrial and military capacity to maintain stockpiles, something you are unable to appreciate I guess. Strike and that will be the ultmate solution to a vexed question. Think clearly and not be jingoistic.
