Abstract
The Global War on Terrorism, launched as a direct result of the heinous 9/11 attacks, has been wagging on for almost two decades with no clear signs of victory for the US. The US on a strategic level has lost the war as the primary opponent, Taliban, holds more territory than ever. The US and NATO coalition not only planned to eradicate terrorism in the country but also had great ambitions to modernize and rebuild the country; however, little has been archived so far. Amidst these harsh realities, Pakistan being a major non-NATO ally is often blamed to sabotage the war efforts by playing a so-called double-game while supporting the Global War on Terrorism on one hand and helping the Taliban on the other. Therefore, this paper investigates the reasons for the US failure in Afghanistan on a macro-level and what role Pakistan has played. Other than the notion that Pakistan is to blame, factors, such as, the US has no real longterm objectives for the war, employing conventional methods of warfare, underestimating the opponent and the terrain, lack of coordination among the NATO member states and the sudden attention shift from Afghanistan to Iraq, played a significant role in the current outcome. After evaluating all the evidence from the last two decades, it is clear that half-baked US planning led to the eventual failure of the war effort.
