Well as you said they WERE. what the hell is your silly 600 000 troop doing in indian occupied kashmir right now? nothing else but terrorising, murdering and making life hell for the Kashmiri people.
You admit the terrorists WERE there. Now. how do we ensure they don't come back en masse? So we keep our army there to protect ourselves. And no, the life of Kashmiri's is no longer hell once the cross border terrorists stop coming. We are not getting business kick started, railroads, roadways etc.
