I forgot to mention the CIA's destruction of any chance of diplomatic or economic pressure against Iran's nuclear program. When CIA said the Iranian's aren't building nukes early this year, the efforts to talk the Iranians out of a nuclear weapons program collapsed, probably for good. CIA bureaucrats managed to torpedo American diplomatic efforts.
I also forgot to mention the CIA's ever so helpful efforts to give credibility to Osama bin Laden's propaganda. Every time bin Laden releases a tape to the media, CIA jumps right out in front and validates the tape as genuine. Instead of allowing the natural doubts about bin Laden's very existance in this world to grow, they tell the world that good old bin Laden must be alive and well. Our enemies, hearing this, think "Well, if the Americans say the tape is genuine, it must be, because the Americans have every reason to declare it fake".
