Editing September 11 attacks (section)

== Background==
===Al-Qaeda===
The origins of al-Qaeda can be traced to 1979 when the Soviet Union invaded Afghanistan. Osama bin Laden travelled to Afghanistan and helped to organize Arab mujahideen to resist the Soviets. Under the guidance of [[Ayman al-Zawahiri]], bin Laden became more radical. In 1996, bin Laden issued his first ''fatwā'', calling for American soldiers to leave Saudi Arabia.

In a second ''fatwā'' in 1998, bin Laden outlined his objections to American foreign policy with respect to Israel, as well as the continued presence of American troops in Saudi Arabia after the Gulf War. Bin Laden used Islamic texts to exhort Muslims to attack Americans until the stated grievances were reversed. Muslim legal scholars "have throughout Islamic history unanimously agreed that the jihad is an individual duty if the enemy destroys the Muslim countries", according to bin Laden.

===Osama bin Laden===
Bin Laden orchestrated the attacks and initially denied involvement but later recanted his false statements. Al Jazeera broadcast a statement by bin Laden on September 16, 2001, stating, "I stress that I have not carried out this act, which appears to have been carried out by individuals with their own motivation." In November 2001, U.S. forces recovered a videotape from a destroyed house in Jalalabad, Afghanistan. In the video, bin Laden is seen talking to Khaled al-Harbi and admits foreknowledge of the attacks. On December 27, 2001, a second bin Laden video was released. In the video, he said:

{{Quote|It has become clear that the West in general and America in particular have an unspeakable hatred for Islam. ... It is the hatred of crusaders. Terrorism against America deserves to be praised because it was a response to injustice, aimed at forcing America to stop its support for Israel, which kills our people. ... We say that the end of the United States is imminent, whether Bin Laden or his followers are alive or dead, for the awakening of the Muslim umma (nation) has occurred}}

but he stopped short of admitting responsibility for the attacks.

Shortly before the U.S. presidential election in 2004, bin Laden used a taped statement to publicly acknowledge al-Qaeda's involvement in the attacks on the United States. He admitted his direct link to the attacks and said they were carried out because:

{{Quote|we are free ... and want to regain freedom for our nation. As you undermine our security, we undermine yours.}}

Bin Laden said he had personally directed his followers to attack the World Trade Center and the Pentagon. Another video obtained by Al Jazeera in September 2006 shows bin Laden with Ramzi bin al-Shibh, as well as two hijackers, Hamza al-Ghamdi and Wail al-Shehri, as they make preparations for the attacks. The U.S. never formally indicted bin Laden for the 9/11 attacks, but he was on the FBI's Most Wanted List for the bombings of the U.S. Embassies in Dar es Salaam, Tanzania, and Nairobi, Kenya. After a 10-year manhunt, U.S. President Barack Obama announced that bin Laden was killed by American special forces in his compound in Abbottabad, Pakistan, on May 1, 2011.

===Khalid Sheikh Mohammed===
Journalist Yosri Fouda of the Arabic television channel Al Jazeera reported that in April 2002, [[Khalid Sheikh Mohammed]] admitted his involvement in the attacks, along with [[Ramzi bin al-Shibh]]. The 2004 9/11 Commission Report determined that the animosity towards the United States felt by Mohammed, the principal architect of the 9/11 attacks, stemmed from his "violent disagreement with U.S. foreign policy favoring Israel". Mohammed was also an adviser and financier of the 1993 World Trade Center bombing and the uncle of [[Ramzi Yousef]], the lead bomber in that attack.

Mohammed was arrested on March 1, 2003, in Rawalpindi, Pakistan, by Pakistani security officials working with the CIA. He was then held at multiple CIA secret prisons and [[Guantanamo Bay detention camp]] he was interrogated and [[torture]]d with methods including [[waterboarding]]. During U.S. hearings at Guantanamo Bay in March 2007, Mohammed again confessed his responsibility for the attacks, stating he "was responsible for the 9/11 operation from A to Z" and that his statement was not made under duress.

A letter presented by the lawyers of Khaled Sheikh Mohammed in the U.S. District Court, Manhattan on 26 July 2019 indicated that he was interested in testifying about Saudi Arabia’s role in the 9/11 attacks and helping the victims and families of the victims of 9/11 in exchange for the United States not seeking the death penalty against him. James Kreindler, one of the lawyers for the victims, raised question over the usefulness of Mohammed.

====Other Al-Qaeda members====
In "Substitution for Testimony of Khalid Sheikh Mohammed" from the trial of [[Zacarias Moussaoui]], five people are identified as having been completely aware of the operation's details. They are bin Laden, Khalid Sheikh Mohammed, [[Ramzi bin al-Shibh]], [[Abu Turab al-Urduni]], and [[Mohammed Atef]]. To date, only peripheral figures have been tried or convicted for the attacks.

On September 26, 2005, the Spanish high court sentenced Abu Dahdah to 27 years in prison for conspiracy on the 9/11 attacks and being a member of the terrorist organization al-Qaeda. At the same time, another 17 al-Qaeda members were sentenced to penalties of between six and eleven years. On February 16, 2006, the Spanish Supreme Court reduced the Abu Dahdah penalty to 12 years because it considered that his participation in the conspiracy was not proven.

Also in 2006, Moussaoui—who some originally suspected might have been the assigned 20th hijacker—was convicted for the lesser role of conspiracy to commit acts of terrorism and air piracy. He was sentenced to life in prison without parole in the United States. Mounir el-Motassadeq, an associate of the Hamburg-based hijackers, served 15 years in Germany for his role in helping the hijackers prepare for the attacks. He was released in October 2018, and deported to Morocco.

The Hamburg cell in Germany included radical Islamists who eventually came to be key operatives in the 9/11 attacks. Mohamed Atta, Marwan al-Shehhi, Ziad Jarrah, Ramzi bin al-Shibh, and Said Bahaji were all members of al-Qaeda's Hamburg cell.

===Motives behind the attack===
Osama bin Laden's declaration of a holy war against the United States, and a 1998 ''fatwā'' signed by bin Laden and others, calling for the killing of Americans, are seen by investigators as evidence of his motivation. In bin Laden's November 2002 "Letter to America", he explicitly stated that al-Qaeda's motives for their attacks include:
* U.S. support of Israel
* support for the "attacks against Muslims" in Somalia
* support of Philippines against Muslims in the Moro conflict
* support for Israeli "aggression" against Muslims in Lebanon
* support of Russian "atrocities against Muslims" in Chechnya
* pro-American governments in the Middle East (who "act as your agents") being against Muslim interests
* support of Indian "oppression against Muslims" in Kashmir
* the presence of U.S. troops in Saudi Arabia
* the sanctions against Iraq
After the attacks, bin Laden and al-Zawahiri released additional videotapes and audio recordings, some of which repeated those reasons for the attacks. Two particularly important publications were bin Laden's 2002 "Letter to America", and a 2004 videotape by bin Laden.

Bin Laden interpreted Muhammad as having banned the "permanent presence of infidels in Arabia".<sup>[50]</sup> 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."

In a December 1999 interview, bin Laden said he felt that Americans were "too near to Mecca", and considered this a provocation to the entire Muslim world. One analysis of suicide [[terrorism]] suggested that without U.S. troops in Saudi Arabia, al-Qaeda likely would not have been able to get people to commit to suicide missions.

In the 1998 ''fatwā'', al-Qaeda identified the Iraq sanctions as a reason to kill Americans, condemning the "protracted blockade" among other actions that constitute a declaration of war against "Allah, his messenger, and Muslims." The ''fatwā'' declared that "the ruling to kill the Americans and their allies – civilians and military – 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."

In 2004, Bin Laden claimed that the idea of destroying the towers had first occurred to him in 1982, when he witnessed Israel's bombardment of high-rise apartment buildings during the 1982 Lebanon War. 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.

Other motives have been suggested in addition to those stated by bin Laden and al-Qaeda. Some authors suggested the "humiliation" that resulted from the Islamic world falling behind the Western world – this discrepancy was rendered especially visible by the globalization trend and a desire to provoke the U.S. into a broader war against the Islamic world in the hope of motivating more allies to support al-Qaeda. 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.

===Planning===
The attacks were conceived by Khalid Sheikh Mohammed, who first presented it to Osama bin Laden in 1996. At that time, bin Laden and al-Qaeda were in a period of transition, having just relocated back to Afghanistan from Sudan. The 1998 African Embassy bombings and bin Laden's February 1998 fatwā marked a turning point of al-Qaeda's terrorist operation,  as bin Laden became intent on attacking the United States.

In late 1998 or early 1999, bin Laden gave approval for Mohammed to go forward with organizing the plot. Mohammed, bin Laden, and bin Laden's deputy [[Mohammed Atef]] held a series of meetings in early 1999. Atef provided operational support, including target selections and helping arrange travel for the hijackers. Bin Laden overruled Mohammed, rejecting potential targets such as the U.S. Bank Tower in Los Angeles for lack of time.

Bin Laden provided leadership and financial support, and was involved in selecting participants. He initially selected Nawaf al-Hazmi and Khalid al-Mihdhar, both experienced jihadists who had fought in the [[Bosnian War]]. Hazmi and Mihdhar arrived in the United States in mid-January 2000. In early 2000, Hazmi and Mihdhar took flying lessons in San Diego, California, but both spoke little English, performed poorly in flying lessons, and eventually served as secondary – or "muscle" – hijackers.

In late 1999, a group of men from Hamburg, Germany arrived in Afghanistan; the group included Mohamed Atta, Marwan al-Shehhi, Ziad Jarrah, and Ramzi bin al-Shibh. Bin Laden selected these men because they were educated, could speak English, and had experience living in the West. New recruits were routinely screened for special skills and al-Qaeda leaders consequently discovered that Hani Hanjour already had a commercial pilot's license. Mohammed later said that he helped the hijackers blend in by teaching them how to order food in restaurants and dress in Western clothing.

Hanjour arrived in San Diego on December 8, 2000, joining Hazmi. They soon left for Arizona, where Hanjour took refresher training. Marwan al-Shehhi arrived at the end of May 2000, while Atta arrived on June 3, 2000, and Jarrah arrived on June 27, 2000. Bin al-Shibh applied several times for a visa to the United States, but as a Yemeni, he was rejected out of concerns he would overstay his visa. Bin al-Shibh stayed in Hamburg, providing coordination between Atta and Mohammed. The three Hamburg cell members all took pilot training in South Florida.

In spring of 2001, the secondary hijackers began arriving in the United States. In July 2001, Atta met with bin al-Shibh in Spain, where they coordinated details of the plot, including final target selection. Bin al-Shibh also passed along bin Laden's wish for the attacks to be carried out as soon as possible. Some of the hijackers received passports from corrupt Saudi officials who were family members, or used fraudulent passports to gain entry.

There is some idea that 9/11 was selected by the hijackers as the date of the attack because of its resemblance to 9-1-1, the phone number to report emergencies in the U.S. However, Lawrence Wright wrote that the hijackers chose it because September 11, 1683 is when the King of Poland began the battle that turned back the Muslim armies from the Ottoman Empire that were attempting to capture Vienna. For Osama bin Laden, this was a date when the West gained some dominance over Islam, and by attacking on this date, he hoped to make a step in Islam "winning" the war for worldwide power and influence.
