From 1980 to 1989, about $600 million is passed through Osama bin Laden’s charity fronts, according to Michael Scheuer, head of the CIA’s first bin Laden unit. Most of it goes through the charity front Maktab al-Khidamat (MAK), also known as Al-Kifah. The money generally comes from donors in Saudi Arabia and the Persian Gulf, and is used to arm and supply the mujaheddin fighting in Afghanistan. Mohammad Yousaf, a high ranking ISI official, will later say, “It was largely Arab money that saved the system,” since so much of the aid given by the CIA and Saudi Arabia was siphoned away before it got to Afghanistan. “By this I mean cash from rich individuals or private organizations in the Arab world, not Saudi government funds. Without those extra millions the flow of arms actually getting to the mujaheddin would have been cut to a trickle.” [Dreyfuss, 2005, pp. 279-280] Future CIA Director Robert Gates will later claim that in 1985 and 1986, the CIA became aware of Arabs assisting and fighting with the Afghan mujaheddin, and the CIA “examined ways to increase their participation, perhaps in the form of some sort of ‘international brigade,’ but nothing came of it.” [Coll, 2004, pp. 146] However, a CIA official involved in the Afghan war will claim that the CIA directly funded MAK (see 1984 and After).
