Actually that's probably the reason why the maximum proponents for an Islamic Caliphate are Pakistanis (ironically the country was never under one for an extended period). You won't find many Turks, Iranians asking for it. IMHO Putting Islam as a binding force removes nationalism, people will see themselves as Muslims first and Pakistanis later
False, the identity of Islam is tied into/intertwined with the national identity of Pakistan ('Islamic Republic of Pakistan'), so it's not even possible for Pakistanis to deal with these two things as two separate, distinct things. I don't know where you came up with that. Pakistan today is not against the vision of Jinnah, as has been explained by my Post # 289. Read it, & then get back.
