Early reports estimated that $6–20 billion had been spent by the U.S. and Saudi Arabia but more recent reports state that the U.S. and Saudi Arabia provided as much as up to $40 billion in cash and weapons, which included over two thousand FIM-92 Stinger surface-to-air missiles, for building up Islamic groups against the Soviet Union.
Os primeiros relatos estiman que $6–20 billóns foron gastados polos Estados Unidos e Arabia Saudita, mais os máis recentes informes afirman que Arabia Saudita e os Estados Unidos proporcionaron até US $40 billóns en diñeiro e armas, para a creación de grupos islámicos contra a Unión Soviética.
