You didn't take half of Kashmir from India. Your Pashtun marauders occupied those parts BEFORE the Indian army stepped in, at the request of the ruler, and prevented the rest from being occupied. You DID NOT capture half of Kashmir from India. It is amazing what sort of stupidities can be taught to Pakistanis even in the information age.
Kashmir was an independent country before your tribals raided it. India stopped your raiding and prevented the best parts of it from being taken. AFTER the rightful ruler acceded to India.
Seriously, learn some history, the rel one, not the one they taught you in school. I don't know how brainless one has to be, to believe these self glorified bravados, like having "taken" half of Kashmir from india and so on. Ah wel, if FACTS come in the way of their one Pakistani = ten Indians theory, manufacture there own facts. Its that simple.
