Truth is indeed usually stranger than fiction, but U.S. motives for fomenting an Islamic uprising in this case would be very esoteric and probably self-defeating. The very fact that the CIA has shot itself in the foot several times leads me to believe that it would be very circumspect about supporting a cultural jihad after the Soviet withdrawal from Pakistan.
"More than a few different sources" lead me to suspect your post is made with tongue fixed firmly in cheek. ;^)
Correction: That should not have been posted, because news of the Soviet presence in Pakistan was suppressed under the orders of the Beta Reticuloids and the Bilderberg Group. :^D
