Pakistan never agreed to demilitirization … period … that is the topic of discussion … even after India agreed (in principle) to allow “some” pakistani troops to be in Pakistani side of Kashmir, even though UNCIP resolutions had called for “complete” withdrawl of Pakistani troops … so you see Pakistan never demilitiraized Kashmir even though you think they did …
CM the point here is not to point fingers at each other … it is to move on and it is time to do so …
