I think the Karachi show is a big success of the establishment as they have achieved 50% of their target by breaking the hegemony of a linguistic cum political party, by bringing all the ethnic group on one platform and by presenting the option of a viable third forces before the people of Pakistan. The remaining 50% of the target depends upon the seats won by PTI in next election.
After all the establishment is pro-Pakistan and think about the welfare of the country and its people.
