The CIA has been a joke for some time. They failed to predict the fall of the Soviet Union, they didn't know about the coup that got rid of Gorbachev. There was even one Soviet defector who, when the CIA gave him nothing to do, went back to the KGB.
If you recall that the second-richest man in America right now is Larry Ellison (CEO of Oracle, mad prophet of National ID cards, former CIA associate), you see what the CIA is really for, which is preening and self-promotion.
The CIA is the largest drug running organization on the planet.
