While dividing the provinces into smaller administrative units is, in principle, long overdue, the current regime isn't doing it for the betterment of the country or its people...... It wants a stronger center and weaker provinces that are easier to subdue, manage and control....
The PPP however will never agree to it because losing Karachi would, for all practical purposes, mean losing everything....... Unless, of course, Asim and co decide to go full throttle....and that would break the current political system....They would have to change the system first in such a way that PPP is no longer needed.....
Most importantly, just like the military dictatorships before it, the current regime seems to believe it will rule forever...... But sada badshahi sirf Allah ki zaat ki hai.
