The Saudi's have been paying for CIA activities in and outside Muslim countries (ex Safari Club)
U.S. Relies Heavily on Saudi Money to Support Syrian Rebels
Dulles — the Princeton man and white shoe corporate lawyer who served as CIA director from 1953 to 1961, still the longest tenure in agency history — died in 1969 before the Safari Club was conceived. And nothing about it appears in The Devil’s Chessboard. But to understand the Safari Club is to understand Allen Dulles and his milieu.
A book by Trento also discsses the Safari Club.
