Part of this Faustian bargain may have involved the House of Saud chieftains providing information to US intelligence on how to create mind-controlled assassins. The Muslim Brotherhood claims to have first perfected this technique during the 11th century Crusades when it launched a brutal parallel secret society known as the Assassins, who employed mind-controlled “lone gunmen” to carry out political assassinations of Muslim Saracen nationalists. The Assassins worked in concert with Knights Templar Christian invaders in their attacks on progressive Arabs, but were repelled.[29]
