Except there is no Punjabi domination. If anything, it is main establishment.
It is Pakistan, not India or Afghanistan where they entertain to the racial cards. It is Pakistan where the actions are defined by the deeds, not race.
Hence, many kind of people ruled Pakistan through the establishment; Ayub Khan, Yahya Khan, Zia-ul-Haq, and Musharraf. Then through the democracy, Liaqat Ali Khan, Zulfiqar Ali Bhutto, Benazir Bhutto, Zardari and Nawaz Sharif. Given the fact that Nawaz Sharif only ruled Pakistan in totaling 7-8 years if this term is completed with peacefully. Does that sound like Punjabi domination? You appear to be clueless troll. Next time, come back with the proper research.
Fun Fact; Ayub Khan silenced the Pukhtoonistan movement generated from Afghanistan in 60s as the leader of Pakistan. Why? Because everyone matters in Pakistan regardless of their background. Pakistan is based on the Allama Iqbal (R.A)'s vision executed by Muhammad Ali Jinnah (R.A). God bless them.
