Pakistan: More Questions About A Closed Border and Burning Tankers (Fair)
why haven't attacks on the supply line to Afghanistan been more common? It's reasonable to argue that a dedicated and sensible insurgent would target these trucks along the way from Karachi to Torkham or to Chaman in Pakistan and from Torkham or Chaman to their final destinations within Afghanistan. This would be simple to do as the Pakistani security forces do not protect those privately-owned trucks and much of the route in Afghanistan winds through narrow mountain passes.
The answer is simple: trucking mafias and organized criminal and insurgent networks are all making money off of this system. The system of payoffs is elaborate yet elegant. Pashtuns dominate the trucking mafia in Pakistan and represent enormous financial interests in the fundamental integrity of the supply line system. The drivers and their companies must pay off Pakistani police and any other relevant government officials to secure "safe" passage and to resolve any "paperwork complexities."
