Proof that the PA calls the shots in foreign policy is the Pak chief always meeting presidents and Prime ministers when the army chiefs have nothing to do with policy which is the prerogative of an elected democratic government. What business does an army general have with heads and duly elected representatives of other nations?
Can you name me one DEMOCRATIC country that allows their chiefs and sundry generals to hob nob with heads of other nations discussing policy? Shouldn't your defence minister or defence secretary be meeting with foreign dignitaries instead of Raheel Sharif for discussing security and related issues?
Here, for example....
With David Cameron
With Defence Secretary Michael Fallon. Where's your defence minister? Or defence secretary?
With US Secretary of State
With Ghani
With Iranian President Hassan Rouhani
It does seem without a doubt that the PA is calling the shots in Pakistan!
