Ali Mohamed is honorably discharged from the US Army with commendations in his file, including one for “patriotism, valor, fidelity, and professional excellence.” He remains in the Army Reserves for the next five years. [New York Times, 12/1/1998; Raleigh News and Observer, 10/21/2001] A US citizen by this time, he will spend much of his time after his discharge in Santa Clara, California, where his wife still resides. He will try but fail to get a job as an FBI interpreter, will work as a security guard, and will run a computer consulting firm out of his home. [San Francisco Chronicle, 9/21/2001]
November 9, 1989: Cold War Ends; Colin Powell Proposes US Should Be ‘Bully on the Block’
The Berlin Wall begins to fall in East Germany, signifying the end of the Soviet Union as a superpower. Just six days later, Joint Chiefs of Staff Chairman Colin Powell will present a new strategy document to President George H. W. Bush, proposing that the US shift its strategic focus from countering Soviet attempts at world dominance to ensuring US world dominance. Bush will accept this plan in a public speech, with slight modifications, on August 2, 1990: the same day Iraq invades Kuwait. In early 1992 (see March 8, 1992), Powell, counter to his usual public dove persona, will tell members of Congress that the US requires “sufficient power” to “deter any challenger from ever dreaming of challenging us on the world stage.” He will say, “I want to be the bully on the block.” Powell’s early ideas of global hegemony will be formalized by others in a 1992 policy document and finally realized as policy when George W. Bush becomes president in 2001. [Harper’s, 10/2002]
November 24, 1989: Bin Laden’s Mentor Assassinated
Osama bin Laden’s mentor Sheikh Abdullah Azzam is killed by a car bomb in Afghanistan. The killing will never be solved. Azzam has no shortage of enemies. Suspects will include the Mossad, CIA, Afghan warlord Gulbuddin Hekmatyar, the ISI, and bin Laden. The reason bin Laden will be suspected is because he and Azzam were increasingly at odds over what approach to take since the Soviet Union had been driven from Afghanistan earlier in the year (see February 15, 1989). [Slate, 4/16/2002; Coll, 2004, pp. 204] In 1998, Mohammed Saddiq Odeh will be arrested and later convicted for a role in the 1998 African embassy bombings. He reportedly will tell US interrogators that bin Laden “personally ordered the killing of Azzam because he suspected his former mentor had ties with the CIA.” However, it is not known if Odeh was just passing on a rumor. [Gunaratna, 2003, pp. 32] Regardless, in the wake of Azzam’s death, bin Laden will take control of Azzam’s recruiting and support network, Maktab al-Khidamat (MAK)/Al-Kifah, and merge it with al-Qaeda, which was formed the year before (see August 11-20, 1988). [Slate, 4/16/2002; Coll, 2004, pp. 204]
Late 1989-Late 1991: Bin Laden Slowly Shifts Operations to Sudan, Keeps Training Camps in Afghanistan
Hassan al-Turabi comes to power in Sudan in 1989, and his beliefs are ideologically compatible with bin Laden’s. With the Afghan war ending and the Afghans beginning to fight amongst themselves, al-Turabi sends a delegation and a letter to bin Laden, inviting him to collaborate and move to Sudan. Bin Laden agrees to the offer, but moves slowly. He sends advance teams to buy businesses and houses. He also visits Sudan himself to establish a relationship with al-Turabi. Gradually, about 1,000 bin Laden supporters move to Sudan. But bin Laden also keeps offices and guest houses in Pakistan, as well as training camps in Afghanistan, including the Darunta, Jihad Wal, Khaldan, Sadeek, Al Farooq, and Khalid ibn Walid camps. US-al-Qaeda double agent Ali Mohamed plays an important role in the move (see Summer 1991). [Gunaratna, 2003, pp. 39-41]
1990: FBI Seizes List of Al-Kifah Contacts
At some point in 1990, the FBI seizes a handwritten list of contacts from a top official of the Al-Kifah Refugee Center in Brooklyn. Al-Kifah is a charity front with links to both al-Qaeda and the CIA (see 1986-1993). Little is known about the list, such as when exactly it was seized and why, what was done with it, or whose names are on it, except that a Texas imam named Moataz Al-Hallak is on the list (mention of the list comes from an article about Al-Hallak). The FBI also seizes a different computerized list of Al-Kifah contacts at some point. [Dallas Morning News, 2/19/1999] It will later be alleged that the CIA repeatedly blocked the FBI’s investigations into Al-Kifah (see Late 1980s and After).
1980s and 1990s: Most 9/11 Hijackers Have Middle-Class Backgrounds
Most of the future 9/11 hijackers are middle class and have relatively comfortable upbringings, even though, after 9/11, some people in Western countries will say one of the root causes of the attacks was poverty and assume that the hijackers must have been poor. The editor of Al Watan, a Saudi Arabian daily, will call the hijackers “middle class adventurers” rather than Islamist fundamentalist ideologues. [Boston Globe, 3/3/2002]

] Maqed Mojed is from Annakhil, near Medina in western Saudi Arabia. [9/11 Commission, 7/24/2004, pp. 232] He attends university (see Late 1990s). Ahmed Alhaznawi is from Hera, Baha Province. His father is an imam at the local mosque and he is reported to attend university (see Late 1990s). Ahmed Alnami is from Abha, Asir Province. His family is one of government officials and scientists, and his father works for the Ministry of Islamic Affairs. He attends university (see Late 1990s). [Daily Telegraph, 9/15/2002] Wail Alshehi and Waleed Alshehri are from Khamis Mushayt in Asir Province, southwestern Saudi Arabia. Their father is a businessman and builds a mosque as a gift to the town. They both go to college (see Late 1990s). The Alshehris are from a military family and have three older brothers who hold high rank at the nearby airbase. Their uncle, Major General Faez Alshehri, is the logistical director of Saudi Arabia’s armed forces. [Boston Globe, 3/3/2002] Dr. Ali al-Mosa, a Saudi academic, will later comment: “Most of them were from very rich, top-class Saudi families. The father of the Alshehri boys is one of the richest people in the area and the other families are not far behind him.” [Sydney Morning Herald, 10/5/2002]
The social situation of the families of Satam al Suqami, Ahmed Alghamdi, Saeed Alghamdi, and Khaled Almihdhar is unknown. However, Almihdhar is from a distinguished family that traces its lineage back to the Prophet Muhammad. [Wright, 2006, pp. 379]
1990-2001: NORAD Regularly Launches Fighters to Intercept Suspicious Aircraft before 9/11
Fighter jets are regularly scrambled by the North American Aerospace Defense Command (NORAD) in response to suspicious or unidentified aircraft flying in US airspace in the years preceding 9/11. [General Accounting Office, 5/3/1994, pp. 4; Associated Press, 8/14/2002] For this task, NORAD keeps a pair of fighters on “alert” at a number of sites around the US. These fighters are armed, fueled, and ready to take off within minutes of receiving a scramble order (see Before September 11, 2001). [American Defender, 4/1998; Air Force Magazine, 2/2002; Bergen Record, 12/5/2003; Grant, 2004, pp. 14] Various accounts offer statistics about the number of times fighters are scrambled: A General Accounting Office report published in May 1994 states that “during the past four years, NORAD’s alert fighters took off to intercept aircraft (referred to as scrambled) 1,518 times, or an average of 15 times per site per year.” Of these incidents, the number of scrambles that are in response to suspected drug smuggling aircraft averages “one per site, or less than 7 percent of all of the alert sites’ total activity.” The remaining activity, about 93 percent of the total scrambles, “generally involved visually inspecting unidentified aircraft and assisting aircraft in distress.” [General Accounting Office, 5/3/1994, pp. 4] In the two years from May 15, 1996 to May 14, 1998, NORAD’s Western Air Defense Sector (WADS), which is responsible for the “air sovereignty” of the western 63 percent of the continental US, scrambles fighters 129 times to identify unknown aircraft that might be a threat. Over the same period, WADS scrambles fighters an additional 42 times against potential and actual drug smugglers. [Washington National Guard, 1998] In 1997, the Southeast Air Defense Sector (SEADS)—another of NORAD’s three air defense sectors in the continental US—tracks 427 unidentified aircraft, and fighters intercept these “unknowns” 36 times. The same year, NORAD’s Northeast Air Defense Sector (NEADS) handles 65 unidentified tracks and WADS handles 104 unidentified tracks, according to Major General Larry Arnold, the commander of the Continental United States NORAD Region on 9/11. [American Defender, 4/1998] In 1998, SEADS logs more than 400 fighter scrambles. [Grant, 2004, pp. 14] In 1999, Airman magazine reports that NORAD’s fighters on alert at Homestead Air Reserve Base in Florida are scrambled 75 times per year, on average. According to Captain Tom Herring, a full-time alert pilot at the base, this is more scrambles than any other unit in the Air National Guard. [Airman, 12/1999] General Ralph Eberhart, the commander of NORAD on 9/11, will later state that in the year 2000, NORAD’s fighters fly 147 sorties. [9/11 Commission, 6/17/2004 ] According to the Calgary Herald, in 2000 there are 425 “unknowns,” where an aircraft’s pilot has not filed or has deviated from a flight plan, or has used the wrong radio frequency, and fighters are scrambled 129 times in response. [Calgary Herald, 10/13/2001] Between September 2000 and June 2001, fighters are scrambled 67 times to intercept suspicious aircraft, according to the Associated Press. [Associated Press, 8/14/2002]
Lieutenant General Norton Schwartz, the commander of the Alaskan NORAD Region at the time of the 9/11 attacks, will say that before 9/11, it is “not unusual, and certainly was a well-refined procedure” for NORAD fighters to intercept an aircraft. He will add, though, that intercepting a commercial airliner is “not normal.” [Air Force Magazine, 9/2011 ] On September 11, 2001, NEADS scrambles fighters that are kept on alert in response to the hijackings (see 8:46 a.m. September 11, 2001 and 9:24 a.m. September 11, 2001).

1990: Ali Mohamed Becomes Informant for FBI
Ali Mohamed, an al-Qaeda operative recently discharged from the US army (see November 1989), becomes an informant for the FBI. He applies to be an translator at FBI offices in Charlotte, North Carolina, and San Francisco, and is turned down. However, the San Francisco office hires him to be an informant to help expose a local document forging conspiracy that possibly involves members of Hamas. [Miller, Stone, and Mitchell, 2002, pp. 144] Mohamed will continue to have connections with the FBI for much of the rest of the 1990s while also running an al-Qaeda cell in California.
1990: Mohamed Atta Joins Muslim Brotherhood Linked Group
In 1990, after finishing his studies in architecture in Egypt, future 9/11 hijacker Mohamed Atta joins what is called an “engineering syndicate,” a professional or trade group. Like the school that trained many of its engineers, the syndicate serves as an unofficial base for the Muslim Brotherhood in Egypt, where the organization recruits new operatives and spreads its ideology. Other members of the 9/11 plot will also have connections to the Muslim Brotherhood at various points in their lives. [Washington Post, 9/22/2001; Observer, 9/23/2001; Newsweek, 12/31/2001]
1990: Islamist Militants Set Up Operations in Bosnia
According to author Richard Labeviere, in this year Talaat Fouad Qassem, a leader of the Egyptian militant group Al-Gama’a al-Islamiyya, is designated by a leaders from different radical militant groups to head up the militant effort in Bosnia. Qassem is living in exile in Denmark and recruits the help of two Algerian militants also living in exile in Europe, Kamer Eddine Kherbane and Abdullah Anas. In future years, the three of them will coordinate all the requests for volunteers from European countries who want to fight in Bosnia. They will send about 2,000 volunteers to camps in Bosnia near the towns of Zenica and Tuzla. Kherbane will directly lead the Tuzla group. [Labeviere, 1999, pp. 73] In 1991, Kherbane will set up a charity front in Croatia that is a branch of Maktab al-Khidamat/Al-Kifah, which is closely tied to al-Qaeda (see 1991 and Early 1990s). In 1995, Qassem will be abducted in Croatia by US forces and killed in Egypt (see
September 13, 1995).
