The creation of new provinces show the state of Pakistan, led by the Establishment, is willing to even annoy its current partners in power to bring positive change in Pakistan. And that speaks volumes! Think of this: Why disturb the apple cart if the desire is just hold onto power? But the inefficiencies of the current system is requiring changes, especially with the Karachiites, who are raging against the rural Sindh.
It would be off topic but I will still say my own opinion: Leave the new provinces debate for some other time but at least do meaningful devolution of power by empowering the Local Bodies and perhaps give a special status to Karachi and Gwadar.
