Wikipedia about Bin Laden: "Under Operation Cyclone from 1979 to 1989, the United States provided financial aid and weapons to the mujahideen through Pakistan's ISI. Bin Laden met and built relations with Hamid Gul, who was a three-star general in the Pakistani army and head of the ISI agency. Although the United States provided the money and weapons, the training of militant groups was entirely done by the Pakistani Armed Forces and the ISI."

So it is still a question what was first, egg or chicken.
