Actually, no. The vast majority of Pakistanis aren't Wahabis, neither are the majority Deobandis. Sure, the former is on the rise, but to suggest it will completely overtake the religious character of a nation of around 200 million is a spurious stretch.
I never made the suggestion of 200 million, you seem to think in absolutes to extract change. The Majority is 51%. 51% is enough to allow for the rest of the national character to be subdued beyond anything more than token presence.
