But it took reading an excellent review by Chalmers Johnson (author of Blowback, The Sorrows of Empire and Nemesis) to really connect the dots.
Furthermore, in his introduction to Johnson's review, Tom Englehardt mentions an important detail about former CIA director William Casey:
...William Casey, the "Catholic Knight of Malta educated by Jesuits," who "believed fervently that by spreading the Catholic Church's reach and power he could contain Communism's advance, or reverse it." And, if you couldn't have the Church do it, as in Afghanistan in the 1980s, then second best, Casey believed, were the Islamic warriors of jihad, the more extreme the better, with whom, in his religio-anticommunism, he believed himself to have much in common. (The enemy of my enemy is my friend, after all.) Casey was, in fact, an American jihadi, eager in the 1980s not just to defeat the Soviets in Afghanistan, but to push "the Afghan jihad into the Soviet Union itself."
I still want to see Charlie Wilson's War, but I think I may wait for the DVD.
