Captain FT,
You have to agree that Punjabi Establishment has ruled the country since 1947. Its policies were not in the interest of Pakistan but only in the interest of Punjab that is why more than half of Pakistan parted away in 1971, and lack of trust by other provinces.
Had Bengalis part of Pakistan, your percentage in combined Pakistan would have not more than 25%. Maulana Abul Kalam Azad predicted this more than six decades ago that making Pakistan would only create Punjabi domination who would not give the other provinces due share. That's why he was not in favor of partition. What he said proved in 1971 and later years.
By nature Punjabis are aggressive, selfish, racists, damn care about others. By the way all these regional parties MQM, JSQM, BNM etc etc are created by Punjabi establishment, to follow the colonial masters the Britishers of divide and rule policy. GET YOUR FACTS CORRECTED.
