The Pakistan President and the Pakistan Govt is sinecure and redundant to policy making.

It is the Army that calls the shot.

As many of you would be aware that the Indian Govt shot down the Army Chief's contention over his age wherein he would have continued longer in office.

Thus there is a joke doing the rounds in India.

"The Govt decides the age of the Army Chief in India,

But the Army decides the age of the Govt in Pakistan!"
