The Durand Line, the western border between Pakistan and Afghanistan, was delineated in 1893 as the boundary between then British India and Afghanistan. The international community recognizes the Durand line as the Pak-Afghan border since the creation of Pakistan in 1947, but successive Afghan rulers have repudiated its legitimacy. This dispute has caused turbulence in relations between these countries and instigates greater problems with regard to the Pashtun nationalism. The Durand Line has remained porous due to the nature of tribal cultures and the socio-economic compulsions of the people living along the Durand line. The Durand Line was exploited to launch the Afghan Jihad against the Soviets in the 1980s. The GWOT in Afghanistan has once again brought misperceptions regarding alignment, and the porous nature of the Durand Line to the lime light. This thesis demonstrates that existing combat operations against Al-Qaeda and the Taliban and the exploitation of the Durand Line by the U.S.-led coalition forces, had a destabilizing effect on Pakistan, due to the autonomous nature of tribal areas and Pakistan's necessity to extend its authority in tribal areas while supporting the GWOT. This thesis recommends that a clear understanding of the Durand Line as an international border by all concerned states will enhance the coordination of operations at all tiers, and thereby prevent this border from becoming South Asia's next trouble spot.
