The correct answer to this question would be E-Osama bin Laden. He was, at one point, backed by the United States. It is a known fact that under the CIA's Operation Cyclone from 1979 to 1989, the United States and Saudi Arabia provided $40 billion worth of financial aid and weapons to almost 100,000 Mujahideen and "Afghan Arabs" from forty Muslim countries through Pakistan's ISI. However, thogh the United States provided the money and weapons, the training of militant groups was entirely done by the Pakistani Armed Forces and the ISI.
