This is the problem that the government of Nawaaz is too distant from reality and the only thing it wants to show is who's in charge. When 4 attacks happened, it was the government job to step up and take control of the situation but they were too busy defending his highness so security institutions took matters into their own hands. Latter Nawaz tried to become the hero and ordered immediate reopening of the border based on Muslim brother and shared culture crap. Now if army intervenes than they will cry huma kaam nahi kerna diya ja raha werna hum Pakistan ko Asian Tiger bana deta. Point being Nawaz has always adopted an approach of conflict with the security institutions. His past track record, Dawn leaks are all a testimony of that.
And if you think I am biased than wait for a second and think on this last time on who's orders were the Afghans given extension when their stay was expired? It was NS despite warning from KPK government and security institutions suggesting against it, he still did it anyway and that too while he was in UK for surgery.
So why is it that he cannot come with a concrete policy over how to deal with this rogue state but only intervenes when others do his job for him? Being the PM and also the Foreign minister, it is his job to come up with a policy to deal with India and Afghanistan and their sponsored terrorism, yet we have seen none from him. So this argument that those who closed it can keep it close is not as simple as you made it to be specially when you have a PM like Nawaz who knows nothing but to remain in a state of conflict with the security institutions of Pakistan.
