Sure Pakistani planners have made mistakes. Who can deny that.
However Pakistani planners have included a lot of Pashtuns at every level of decision making. They have included Mullahs, Generals, the seculars, and nationalists.
So it is not good to name Pakistan, India, and Afghanistan, and Harry Potter as the problem sources, and let the Pashtuns themselves go scott free.
Afghanistan has been destroyed mainly by Pashtuns themselves. And so has the death and destruction in FATA and Swat been mainly from the very hands of Pashtuns.
It is time that Pashtuns take responsibility of their own mistakes and start changing themselves first.
