Donald Rumsfeld
The United States was attacked on September 11, 2001 by al Qaeda terrorists who hijacked commercial airliners and crashed them in coordinated strikes into both towers of the World Trade Center in Lower Manhattan, New York City and the Pentagon in Washington, D.C. The fourth plane crashed into a field in Shanksville, Pennsylvania, and its target was likely a prominent building in Washington, D.C., most probably either the Capitol Building or the White House. Within three hours of the start of the first hijacking and two hours after American Airlines Flight 11 struck the World Trade Center, Rumsfeld raised the defense condition signaling of the United States offensive readiness to DEFCON 3, the highest it had been since the Arab-Israeli war in 1973.
Osama bin Laden
In the 2004 video, bin Laden abandoned his denials without retracting past statements. In it he said he had personally directed the nineteen hijackers. In the 18-minute tape, played on Al-Jazeera, four days before the American presidential election, bin Laden accused U.S. President George W. Bush of negligence in the hijacking of the planes on September 11. According to the tapes, bin Laden claimed he was inspired to destroy the World Trade Center after watching the destruction of towers in Lebanon by Israel during the 1982 Lebanon War.
