September 1999 (C): A report prepared for US intelligence entitled the "Sociology and Psychology of Terrorism" is completed. It states: "Al-Qaeda's expected retaliation for the US cruise missile attack ... could take several forms of terrorist attack in the nation's capital. Al-Qaeda could detonate a Chechen-type building-buster bomb at a federal building. Suicide bomber(s) belonging to al-Qaeda's Martyrdom Battalion could crash-land an aircraft packed with high explosives (C-4 and Semtex) into the Pentagon, the headquarters of the Central Intelligence Agency (CIA), or the White House. Whatever form an attack may take, bin Laden will most likely retaliate in a spectacular way." The report is by the National Intelligence Council, which advises the President and US intelligence on emerging threats. [AP, 4/18/02, read the complete report on-line] The Bush administration later claims to have never heard of this report until May 2002, despite the fact that it had been publicly posted on the internet since 1999, and "widely shared within the government" according to the New York Times.
