The 9/11 was a paradigm shifting event in the international and global politics. On September 11, 2001, two jet planes hit the twin's tower in United States of America (USA). US official authorities said that it is done by alQaeda. This event also changes Pakistan's internal and foreign policies. The government of United States compel Afghan Taliban government to handover the master mind of 9/11 attack and their leader Osama bin Laden but the talks failed between the both governments. Therefore US government compel the government of Pakistan to give us Military bases and assistance against Afghan Taliban. Pakistan agreed with US as frontline ally of US in war on terror. The majority of Pakistani people were not happy with the decision, therefore, some non-state actors appeared in different part of the country especially in Malakand Division and FATA to support Taliban regime in Afghanistan. In Malakand Division Mulana Sufi Muhammad head of Tehrik Nifaz-e-Shariat-e-Muhammadi started a proper armed campaign for Afghan Taliban Support and sent thousands of people to Afghanistan support Taliban against US and their allied forces. It was a basic reason behind the emergence of terrorism in Malakand division KP but it did not played it role alone to cause terrorism in the region. Many other important factors i.e. weak political administration, unemployment, economic deprivation, socio-political instability constituted the main reason that opened room for non-state actors to consolidate their grip on the region.
