Pakistan is sealing border with Afghanistan to register the movement across the border and make sure terrorists do not get facilitated by an open border. Please note Torkham border was used in many occasions by terrorist to come into Pakistan and conduct attacks, the recent attack being in Bacha Khan University.
The only reason i can think of not letting these installations being built is to make sure terrorists and the refugees keep on flowing in. And going on to justify this act....wow!
We should continue with the fencing and all, keep vigilant and be ready for any attack.
