Pakistan-Afghanistan border is an haritage of British Raj. Brittons decided to use local tribal militia as a border guard after two attempts to enforce their power on to local Pashtun tribes. Such solution occured quite effective during collonial rule. Pakistan inharited that and incorporated in their system. During Soviet invasion in to Afghanistan it has been currupted by Arab-Salafi fighters presence and collapse of local tribal structures. After Soviet withdrawal from Afganistan, Af-Pak frontier became virtually lawless area and local militias were underdeveloped because they were concideret un-trustworthy. The situation has changed afer 9/11 when the USA supported modernization of Pakistani Frontier Corps. Present situation is a kind of synthesis between traditional tribal militias of British Raj and regular warfare of modern battlefield. Even so, present government in Islamabad has no full confidence in the Frontier Corps.It is worried aboud possibility of further emancipation of Pashtun tribes and Pashtuns in general which may lead to proclamation of independence of Pashtunistan. It would mean replication of the process of freedom-fighting of Bengalis and 1971 War for their independence.
