Pakistan is not a "highly radicalized society", if anything the radicals are concentrated in a very small part of the country called Waziristan. If Pakistan is such a "highly radicalized society" then why is it only after the WoT is Pakistan facing this TTP militancy? See the problem with some people is they perceive anti-western sentiment as " highly radicalized". I think you are buying too much into the international propaganda about Pakistan.
Punjab is Pakistan's most populated province, it is not "highly radicalized" nor is Sindh, Balochistan, Kashmir, it's NWFP where the militancy is, though largely eradicated they still operate underground.
So how can Pakistan be a "highly radicalized society" if it's main provinces are largely moderate? Yes there are liberals, moderates, and conservatives, but "highly radicalized" not much throughout the 175 million population.
