During the Soviet-Afghan War, all our support went to the local Afghan guerilla movements who were for the most part more nationalist than Islamist, such as Ahmed Shah Massoud. Bin Laden and his fellow foreigners had to rely on Saudi and other Gulf Arab money for their support. In fact, bin Laden admitted to Robert Fisk in a interview that he never received any American support.
Massoud was taken out by AQ right before 9/11.
