The NATO council declared that the terrorist attacks on the United States were an attack on all NATO nations that satisfied Article 5 of the NATO charter. This marked the first invocation of Article 5, which had been written during the Cold War with an attack by the Soviet Union in mind. Australian Prime Minister John Howard who was in Washington, D.C. during the attacks invoked Article IV of the ANZUS treaty. The Bush administration announced a War on Terror, with the stated goals of bringing bin Laden and al-Qaeda to justice and preventing the emergence of other terrorist networks. These goals would be accomplished by imposing economic and military sanctions against states harboring terrorists, and increasing global surveillance and intelligence sharing.
Cantor Fitzgerald L.P., an investment bank on the 101st–105th floors of the North Tower, lost 658 employees, considerably more than any other employer. Marsh Inc., located immediately below Cantor Fitzgerald on floors 93–100, lost 358 employees, and 175 employees of Aon Corporation were also killed. The National Institute of Standards and Technology (NIST) estimated that about 17,400 civilians were in the World Trade Center complex at the time of the attacks. Turnstile counts from the Port Authority suggest 14,154 people were typically in the Twin Towers by 8:45 a.m. Most people below the impact zone safely evacuated the buildings.
More InfoThe attacks caused the deaths of 2,996 people (including all 19 hijackers) and injured more than 6,000 others. The death toll included 265 on the four planes (from which there were no survivors), 2,606 in the World Trade Center and in the surrounding area, and 125 at the Pentagon. Most of those who perished were civilians, with the exception of 343 firefighters, 72 law enforcement officers, 55 military personnel, and the 19 terrorists who died in the attacks. After New York, New Jersey lost the most state citizens, with the city of Hoboken having the most New Jersey citizens who died in the attacks. More than 90 countries lost citizens in the September 11 attacks; for example, the 67 Britons who died were more than in any other terrorist attack anywhere as of October 2002. The attacks killed about 500 more people than the attack on Pearl Harbor on December 7, 1941, and are the deadliest terrorist attacks in world history.
More InfoAt least 200 people fell or jumped to their deaths from the burning towers (as exemplified in the photograph The Falling Man), landing on the streets and rooftops of adjacent buildings hundreds of feet below. Some occupants of each tower above the point of impact made their way toward the roof in the hope of helicopter rescue, but the roof access doors were locked. No plan existed for helicopter rescues, and the combination of roof equipment, thick smoke, and intense heat prevented helicopters from approaching. A total of 411 emergency workers died as they tried to rescue people and fight fires. The New York City Fire Department (FDNY) lost 343 firefighters, including a chaplain and two paramedics. The New York City Police Department (NYPD) lost 23 officers. The Port Authority Police Department (PAPD) lost 37 officers. Eight emergency medical technicians (EMTs) and paramedics from private emergency medical services units were killed.
More InfoIn the largest restructuring of the U.S. government in contemporary history, the United States enacted the Homeland Security Act of 2002, creating the Department of Homeland Security. Congress also passed the USA PATRIOT Act, saying it would help detect and prosecute terrorism and other crimes. Civil liberties groups have criticized the PATRIOT Act, saying it allows law enforcement to invade the privacy of citizens and that it eliminates judicial oversight of law enforcement and domestic intelligence. In an effort to effectively combat future acts of terrorism, the National Security Agency (NSA) was given broad powers. NSA commenced warrantless surveillance of telecommunications, which was sometimes criticized since it permitted the agency "to eavesdrop on telephone and e-mail communications between the United States and people overseas without a warrant". In response to requests by various intelligence agencies, the United States Foreign Intelligence Surveillance Court permitted an expansion of powers by the U.S. government in seeking, obtaining, and sharing information on U.S. citizens as well as non-U.S. people from around the world.
More InfoBin Laden interpreted Muhammad as having banned the "permanent presence of infidels in Arabia". In 1996, bin Laden issued a fatwā calling for American troops to leave Saudi Arabia. In 1998, al-Qaeda wrote, "for over seven years the United States has been occupying the lands of Islam in the holiest of places, the Arabian Peninsula, plundering its riches, dictating to its rulers, humiliating its people, terrorizing its neighbors, and turning its bases in the Peninsula into a spearhead through which to fight the neighboring Muslim peoples."
