Mr. Paracha is spot on -- the creation of "ideology" of Islam-ization is already the source of much regret and will in the future give Pakistanis and those who get in their way, even more cause to lament.
But the source of the problem is not the role of religion, it is the question of the quality of values that inform that religiosity -- the reason both Pakistanis and those get in their way have much to fear from this ideology, is that it is bereft of Islam but it is full of tribal notions - Rahman and Raheem, though they are the most frequently used qualities to describe God in Quran, find not just little expression but outright rejection in the ideology of Islam in Pakistan.
With your permission, allow me to add that Pakistan must have Islam - but Pakistan must decide what is the content of that Islam - we know that it cannot be the Islam of the house of Saud and the Wahabi (anyone familiar with how it was forced upon the Arabian Peninsula and the quality of it's ideas, will realize that it cannot suit a modern nation state, that it is in fact the bringer of the end of the nation state) -- So Pakistanis cannot escape this, they must fashion a workable response and create Islam in Pakistan - my guess is that it will not be very different from the way we understood Islam before the Arabization of Pakistan - or if not, Pakistanis will suffer greater humiliations and misfortunes.
