2002 State of the Union Address
Bush spoke about the September 11 attacks of the previous year that killed thousands of people in New York City, Virginia, and Pennsylvania. The Islamist terrorist organization al-Qaeda carried out the attack with 19 hijackers that took over four commercial airline flights and crashed them into the World Trade Center's Twin Towers in New York City's Lower Manhattan, and into the Pentagon in Virginia's Arlington County.
Responsibility for the September 11 attacks
Intelligence experts speak of a "short list" of prime suspects—groups that possess both the means and the motive to carry out the crime. Two of the passengers had been identified as al-Qaeda members and were on the FBI's terrorist-alert list prior to 9/11: Khalid Almihdhar and Nawaf Alhazmi. It appears certain that all hijackers had Arab origins, and none were Afghan; moreover, both in their immense scale, careful planning and refraining from claiming responsibility, the attacks are reminiscent of al-Qaeda's previous attacks such as the 1998 US embassy bombings that killed over 200 people.
