September 11th was by far the largest intelligence failure in United States history. In 1996, the Philippines warned the FBI of terrorists thinking about taking flight school. Later that year, Somalia offered to turn Osama Bin Laden over to Saudi Arabian authorities, but they declined and he got off scott-free.
             In January of 2000, at the terrorist summit in Malaysia, the CIA scopes out two men who have airplane tickets to the United States. They contact the FBI and brief them about the two men and suggest putting them on the watch list. It never gets done.
             In February of 2001, the director of CIA, George Tenet, warns the FBI that Bin Laden is planning a future attack on the United States. Later, in July, more warnings are called in to the FBI stating that many "middle eastern" men are taking flight school training in Arizona and Florida. The unidentified caller strongly urges they be put on the watch list.
             In August, President Bush gets a briefing from the CIA stating that Osama Bin Laden and his terrorist network, Al Queda, are planning a to highjack a plane soon, and attack the United States. Bush tries to act on the message, but doesn't have enough time to stop it before it happens. On September 10, the NSA records an encrypted message from Saudi Arabia to Afghanistan saying, "Tomorrow is zero hour," and "Tomorrow, it begins." It took two days to decode the message but it was too late.
             The United States had all of the pieces to the jig saw puzzle of a plan when it cam to stopping the terrorist attacks on September 11, 2001. They just never put them together, thus causing the largest intelligence failure ever, and the loss of thousands of lives
