qwerty: The CIA, huh? You realize that if the CIA were trying to assassinate Bhutto, they would have offed Chavez in Venezuela instead. These guys can’t find their a** with a flashlight and both hands.
Feeding the conspiracy beast, though, I would suggest it is more likely that Musharraf did the deed and then blamed al Qaeda. Two birds with one stone: You get rid of a highly popular opposition leader, and also put yourself in a position to capture even more power in order to bring al Qaeda to heel.
