I know arguing with you and nearly all Indians is wastage of time. But still, US is playing a double game with us, to put in simple, so if US isn't sincere, then we can't be. They have their own game being played, and we need to devise our game to counter them. And another thing, you guys may think India is the innocent of all, which is isn't. So Pakistan's concerns of another hostile western flank are based on ground realities, which we can't afford. History is testament to that. Which are being repeated now, with same players, few new and a much big larger game this time. We don't have any strategic dept issue, all we want is a neutral non-hostile Afghanistan, which with current players is not possible. So for our own sovereignty and security, we have been forced to play such a dirty game.
Try to see the big picture, of what the real intentions of US are in this region.
