Four passenger airliners operated by two major U.S. passenger air carriers (United Airlines and American Airlines)—all of which departed from airports in northeastern United States bound for San Francisco and Los Angeles—were hijacked by 19 al-Qaeda terrorists. Two of the planes, American Airlines Flight 11 and United Airlines Flight 175, were crashed into the North and South towers, respectively, of the World Trade Center complex in Lower Manhattan. Within an hour and 42 minutes, both 110-story towers collapsed. Debris and the resulting fires caused a partial or complete collapse of all other buildings in the World Trade Center complex, including the 47-story 7 World Trade Center tower, as well as significant damage to ten other large surrounding structures. A third plane, American Airlines Flight 77, was crashed into the Pentagon (the headquarters of the U.S. Department of Defense) in Arlington County, Virginia, which led to a partial collapse of the building's west side. The fourth plane, United Airlines Flight 93, was initially flown toward Washington, D.C., but crashed into a field in Stonycreek Township near Shanksville, Pennsylvania, after its passengers thwarted the hijackers. 9/11 is the single deadliest terrorist attack in human history and the single deadliest incident for firefighters and law enforcement officersBOOK, Congress, Congressional Record, Vol. 148, Pt. 7, May 23, 2002 to June 12, 2002,weblink April 9, 2014, Government Printing Office, 9909, 978-0-16-076125-6, May 2006, in the history of the United States, with 343 and 72 killed, respectively.Suspicion quickly fell on al-Qaeda. The United States responded by launching the War on Terror and invading Afghanistan to depose the Taliban, which had failed to comply with U.S. demands to extradite Osama bin Laden and expel al-Qaeda from Afghanistan.

After evading capture for almost a decade, bin Laden was located in Pakistan and killed by SEAL Team Six of the U.S. Navy in May 2011.The destruction of the World Trade Center and nearby infrastructure seriously harmed the economy of Lower Manhattan and had a significant effect on global markets, which resulted in the closing of Wall Street until September 17 and the civilian airspace in the U.S. and Canada until September 13. Many closings, evacuations, and cancellations followed, out of respect or fear of further attacks.

The fatwā declared that "the ruling to kill the Americans and their allies â€“ civilians and military â€“ is an individual duty for every Muslim who can do it in any country in which it is possible to do it, in order to liberate the al-Aqsa Mosque and the holy mosque of Mecca from their grip, and in order for their [the Americans'] armies to move out of all the lands of Islam, defeated and unable to threaten any Muslim."See also the 1998 Al-Qaeda fatwā: "The ruling to kill the Americans and their allies â€“ civilians and military â€“ is an individual duty for every Muslim who can do it in any country in which it is possible to do it, in order to liberate the al-Aqsa Mosque and the holy mosque [Mecca] from their grip, and in order for their armies to move out of all the lands of Islam, defeated and unable to threaten any Muslim."

Some analysts, including Mearsheimer and Walt, also claimed that U.S. support of Israel was one motive for the attacks. In 2004 and 2010, bin Laden again connected the September 11 attacks with U.S. support of Israel, although most of the letter expressed bin Laden's disdain for President Bush and bin Laden's hope to "destroy and bankrupt" the U.S.WEB, Full transcript of bin Ladin's speech,weblink Al Jazeera, August 24, 2016, November 4, 2004, In his taped broadcast from January 2010, Bin Laden said "Our attacks against you [the United States] will continue as long as U.S. support for Israel continues. ...

In Bernard Lewis's 2004 book (The Crisis of Islam: Holy War and Unholy Terror), he argues that animosity toward the West is best understood with the decline of the once powerful Ottoman empire, compounded by the import of western ideas â€“ Arab socialism, Arab liberalism and Arab secularism. During the past three centuries, according to this interpretation, the Islamic world has lost its dominance and its position of leadership in the world, and has fallen behind both the modern West and the rapidly modernizing Orient. The resulting widening gap poses increasingly severe problems, both practical and emotional, for which the rulers, thinkers, and rebels of Islam have not yet found effective answers.In an essay titled "The spirit of terrorism", Jean Baudrillard described 9/11 as the first global event that "questions the very process of globalization".

Similarly, others have argued that 9/11 was a strategic move with the objective of provoking America into a war that would incite a pan-Islamic revolution.In an essay entitled "Somebody Else's Civil War", Michael Scott Doran argues the attacks are best understood as part of a religious conflict within the Muslim world and that Bin Laden's followers "consider themselves an island of true believers surrounded by a sea of iniquity". Hoping that U.S. retaliation would unite the faithful against the West, bin Laden sought to spark revolutions in Arab nations and elsewhere. Doran argues the Osama bin Laden videos attempt to provoke a visceral reaction in the Middle East and ensure that Muslim citizens would react as violently as possible to an increase in U.S. involvement in their region.

Prior intelligence

In late 1999, al-Qaeda associate Walid bin Attash ("Khallad") contacted Mihdhar, telling him to meet him in Kuala Lumpur, Malaysia; Hazmi and Abu Bara al Yemeni would also be in attendance. The NSA intercepted a telephone call mentioning the meeting, Mihdhar, and the name "Nawaf" (Hazmi). While the agency feared "Something nefarious might be afoot", it took no further action. The CIA had already been alerted by Saudi intelligence about the status of Mihdhar and Hazmi as al-Qaeda members, and a CIA team broke into Mihdhar's Dubai hotel room and discovered that Mihdhar had a U.S. visa. While Alec Station alerted intelligence agencies worldwide about this fact, it did not share this information with the FBI. The Malaysian Special Branch observed the January 5, 2000 meeting of the two al-Qaeda members, and informed the CIA that Mihdhar, Hazmi, and Khallad were flying to Bangkok, but the CIA never notified other agencies of this, nor did it ask the State Department to put Mihdhar on its watchlist. An FBI liaison to Alec Station asked permission to inform the FBI of the meeting but was told: "This is not a matter for the FBI."{{sfnp|Wright|2006|pp=310–312}}By late June, senior counter-terrorism official Richard Clarke and CIA director George Tenet were "convinced that a major series of attacks was about to come", although the CIA believed the attacks would likely occur in Saudi Arabia or Israel.{{sfnp|Clarke|2004|pp=235–236}} In early July, Clarke put domestic agencies on "full alert", telling them, "Something really spectacular is going to happen here ... soon." He asked the FBI and the State Department to alert the embassies and police departments, and the Defense Department to go to "Threat Condition Delta."{{sfnp|Wright|2006|p=344}}{{sfnp|Clarke|2004|pp=236–237}} Clarke would later write: "Somewhere in CIA there was information that two known al Qaeda terrorists had come into the United States. [...] in [the] FBI there was information that strange things had been going on at flight schools in the United States. [...] They had specific information about individual terrorists. [...] None of that information got to me or the White House."{{sfnp|Clarke|2004|pp=242–243}}On July 13, Tom Wilshire, a CIA agent assigned to the FBI's international terrorism division, emailed his superiors at the CIA's Counterterrorism Center (CTC) requesting permission to inform the FBI that Hazmi was in the country and that Mihdhar had a U.S. visa. The CIA never responded.{{sfnp|Wright|2006|p=340}}The same day in July, Margarette Gillespie, an FBI analyst working in the CTC, was told to review material about the Malaysia meeting. She was not told of the participants' presence in the U.S. The CIA gave Gillespie surveillance photos of Mihdhar and Hazmi from the meeting to show to FBI counterterrorism, but did not tell her their significance. The Intelink database informed her not to share intelligence material on the meeting to criminal investigators. When shown the photos, the FBI were refused more details on their significance, and they were not given Mihdhar's date of birth nor passport number.{{sfnp|Wright|2006|pp=340–343}} In late August 2001, Gillespie told the INS, the State Department, the Customs Service, and the FBI to put Hazmi and Mihdhar on their watchlists, but the FBI was prohibited from using criminal agents in the search for the duo, which hindered their efforts.{{sfnp|Wright|2006|pp=352–353}}Also in July, a Phoenix-based FBI agent sent a message to FBI headquarters, Alec Station, and to FBI agents in New York alerting them to "the possibility of a coordinated effort by Osama bin Laden to send students to the United States to attend civil aviation universities and colleges." The agent, Kenneth Williams, suggested the need to interview all flight school managers and identify all Arab students seeking flight training.{{sfnp|Wright|2006|p=350}} In July, Jordan alerted the U.S. that al-Qaeda was planning an attack on the U.S.; "months later", Jordan notified the U.S. that the attack's codename was "The Big Wedding" and that it involved airplanes.{{sfnp|Yitzhak|2016|p=218}}On August 6, 2001, the CIA's Presidential Daily Brief ("PDB"), designated "For the President Only", was entitled "Bin Ladin Determined to Strike in U.S." The memo noted that "The FBI information ... indicates patterns of suspicious activity in this country consistent with preparations for hijackings or other types of attacks."WEB, THE OSAMA BIN LADEN FILE: National Security Archive Electronic Briefing Book No. 343,weblink The National Security Archive, The National Security Archive, March 14, 2016, In mid-August, one Minnesota flight school alerted the FBI about Zacarias Moussaoui, who had asked "suspicious questions."

Their request to search his laptop was denied by FBI headquarters due to the lack of probable cause.{{sfnp|Wright|2006|pp=350–351}}The failures in intelligence-sharing were attributed to 1995 Justice Department policies limiting intelligence sharing, combined with CIA and NSA reluctance to reveal "sensitive sources and methods" such as tapped phones.{{sfnp|Wright|2006|pp=342–343}} Testifying before the 9/11 Commission in April 2004, then-Attorney General John Ashcroft recalled that the "single greatest structural cause for the September 11th problem was the wall that segregated or separated criminal investigators and intelligence agents."{{sfnp|Javorsek II|Rose|Marshall|Leitner|2015|p=742}} Clarke also wrote: "There were failures in the organizations [...] failures to get information to the right place at the right time."{{sfnp|Clarke|2004|p=238}}

Under such conditions, the ensuing fire would be sufficient to cause instability and initiate collapse.

Even if all of the columns and girders had survived the impact â€“ an unlikely event â€“ the structure would fail as the result of a buckling of the columns. The heat from an ordinary office fire would suffice to soften and weaken the unprotected steel. Evaluation of the effects of the fire on the core column structure, with the insulation removed by the impact, showed that collapse would follow whatever the number of columns cut at the time of the impact., The director of the original investigation stated that "the towers really did amazingly well.
