Swat is a good example to see how extremism develops. In 2006 I went to the area with my friends. We offered prayers in mosque (belonging to Jud or Fazlullah). We had people from different sects like Shia, Sunni or non-taqleedis but no one in the mosque bothered to question our different ways of praying and everyone was normal about it.
Similarly there were tourists with different social-class backgrounds and dressed up like the way they do in Karachi, Islamabad etc and no one bothered to question their dresses. There were girls school in the area and no one bothered to blow them up. Things started to go bad in the area when Army demolished the local structure which created vacuum for these groups to take over and especially when Lal-Masjid operation was conducted (The operation itself was sectarian and social-class fascism backed) , it gave a message to the people that there ways are in danger now and so they went on to the path of extremism. Its very easy for us to consider others as evil aliens and point fingers at them but to resolve a problem, an honest analysis is required to see where it all started and where the root cause lies.
Swat, Tribal areas etc were promised that their autonomy will remain in tact if they join Pakistan but Army on various occasions from 60s violated these agreements and started to meddle in there affairs especially in Musharraf’s time they deliberately targeted their religious schools and institutions. It seems that army used this war not only to bag dollars from Americans but also to pursue their old goal of invading these tribal areas because they seem to love only that Pakistan which is under their boots otherwise they will do another Bangladesh with that part of the country like they are also doing with Baluchistan.
People are again chanting slogans for more War in North Waziristan especially after Malala Yousafzai attack. They should ask their self about the goals they have achieved after decades of military operations in FATA, Baluchistan and Swat. These operations have resulted in more extremism and more terrorism, and they are not going to give different results in the future except things will go worse.
