Peter Burgess COMMENTARY

The events of 9/11 shook up the United States and the world.

I was in Manhattan when the planes hit the World Trade Center ... first one tower and then the other. The World Trade Center is in the financial district at the southern tip of Manhattan. I watched from midtown at the South end of Central Park ... esentially at the intersection of Avenue of he Americas (6th Avenue 0 and Central Parl South (59th Street). From this vantage point I was able to see down 6th Avenue all the way to the location of the World Trade Center.

At the time, my wife worked at New York Presbyterian Hospital. As soon as the attack started it was anticipated that there would be 'mass casualities; and the hospital got itself prepared to treat the injured.

By the end of the day, there were few people to be treated in a hospital setting. Thousands ... no exageration ... were dead.

A day or two after 9/11, I was taken around the emergency burn facilities that had been mobilized at the New York Presbyterian Hospital ...it was impressive, but essentially no patients ..a few, but nothing like what had been expected.

Instead of work to help the injured, refrigerated trucks were mobilized to serve as temporary morgues at many of the hospitals around the city inlcuding NYP to handle the deceased!

On September 11, 2001, groups of attackers boarded four domestic aircraft at three East Coast airports, and soon after takeoff they disabled the crews, some of whom may have been stabbed with box cutters the hijackers were secreting. The hijackers then took control of the aircraft, all large and bound for the West Coast with full loads of fuel. At 8:46 am the first plane, American Airlines flight 11, which had originated from Boston, was piloted into the north tower of the World Trade Center in New York City. Most observers construed this initially to be an accident involving a small commuter plane. The second plane, United Airlines flight 175, also from Boston, struck the south tower 17 minutes later. At this point there was no doubt that the United States was under attack. Each structure was badly damaged by the impact and erupted into flames. Office workers who were trapped above the points of impact in some cases leapt to their deaths rather than face the infernos now raging inside the towers. The third plane, American Airlines flight 77, taking off from Dulles Airport near Washington, D.C., struck the southwest side of the Pentagon (just outside the city) at 9:37 am, touching off a fire in that section of the structure. Minutes later the Federal Aviation Authority ordered a nationwide ground stop, and within the next hour (at 10:03 am) the fourth aircraft, United Airlines flight 93 from Newark, New Jersey, crashed near Shanksville in the Pennsylvania countryside after its passengers—informed of events via cellular phone—attempted to overpower their assailants.

At 9:59 am the World Trade Center’s heavily damaged south tower collapsed, and the north tower fell 29 minutes later. Clouds of smoke and debris quickly filled the streets of Lower Manhattan. Office workers and residents ran in panic as they tried to outpace the billowing debris clouds. A number of other buildings adjacent to the twin towers suffered serious damage, and several subsequently fell. Fires at the World Trade Center site smoldered for more than three months.

Rescue operations began almost immediately as the country and the world sought to come to grips with the enormity of the losses. Nearly 3,000 people had perished: some 2,750 people in New York, 184 at the Pentagon, and 40 in Pennsylvania; all 19 terrorists also died. Included in the total in New York City were more than 400 police officers and firefighters, who lost their lives after rushing to the scene and into the towers.

On the morning of September 11, President Bush had been visiting a second-grade classroom in Sarasota, Florida, when he was informed that a plane had flown into the World Trade Center. A little later Andrew Card, his chief of staff, whispered in the president’s right ear: “A second plane hit the second tower. America is under attack.” To keep the president out of harm’s way, Bush subsequently hopscotched across the country on Air Force One, landing in Washington, D.C., the evening of the attacks. At 8:30 pm Bush addressed the nation from the Oval Office in a speech that laid out a key doctrine of his administration’s future foreign policy: “We will make no distinction between the terrorists who committed these acts and those who harbor them.”

On September 14 Bush visited “Ground Zero,” the smoking pile of debris of what remained of the World Trade Center and the thousands who had perished there. Standing on top of a wrecked fire truck, Bush grabbed a bullhorn to address the rescue workers working feverishly to find any survivors. When one of the workers said that he could not hear what the president was saying, Bush made one of the most memorable remarks of his presidency:

I can hear you. The rest of the world hears you. And the people who knocked these buildings down will hear from all of us soon.

Bush’s robust response to the attacks drove his poll ratings from 55 percent favourable before September 11 to 90 percent in the days after, the highest ever recorded for a president.

The emotional distress caused by the attacks—particularly the collapse of the twin towers, New York City’s most visible landmark—was overwhelming. Unlike the relatively isolated site of the Pearl Harbor attack of 1941, to which the September 11 events were soon compared, the World Trade Center lay at the heart of one of the world’s largest cities. Hundreds of thousands of people witnessed the attacks firsthand (many onlookers photographed events or recorded them with video cameras), and millions watched the tragedy unfold live on television. In the days that followed September 11, the footage of the attacks was replayed in the media countless times, as were the scenes of throngs of people, stricken with grief, gathering at “Ground Zero”—as the site where the towers once stood came to be commonly known—some with photos of missing loved ones, seeking some hint of their fate.

Moreover, world markets were badly shaken. The towers were at the heart of New York’s financial district, and damage to Lower Manhattan’s infrastructure, combined with fears of stock market panic, kept New York markets closed for four trading days. Markets afterward suffered record losses. The attacks also stranded tens of thousands of people throughout the United States, as U.S. airspace remained closed for commercial aviation until September 13, and normal service, with more rigid security measures, did not resume for several days.

The September 11 attacks were an enormous tactical success for al-Qaeda. The strikes were well coordinated and hit multiple targets in the heart of the enemy, and the attacks were magnified by being broadcast around the world to an audience of untold millions. The September 11 “propaganda of the deed” took place in the media capital of the world, which ensured the widest possible coverage of the event. Not since television viewers had watched the abduction and murder of Israeli athletes during the Munich Olympics in 1972 had a massive global audience witnessed a terrorist attack unfold in real time. If al-Qaeda had been a largely unknown organization before September 11, in the days after it became a household name.

After the attacks of September 11, countries allied with the United States rallied to its support, perhaps best symbolized by the French newspaper Le Monde’s headline, “We are all Americans now.” Even in Iran thousands gathered in the capital, Tehrān, for a candlelight vigil.

Evidence gathered by the United States soon convinced most governments that the Islamic militant group al-Qaeda was responsible for the attacks. The group had been implicated in previous terrorist strikes against Americans, and bin Laden had made numerous anti-American statements. Al-Qaeda was headquartered in Afghanistan and had forged a close relationship with that country’s ruling Taliban militia, which subsequently refused U.S. demands to extradite bin Laden and to terminate al-Qaeda activity there.

For the first time in its history, the North Atlantic Treaty Organization (NATO) invoked Article 5, allowing its members to respond collectively in self-defense, and on October 7 the U.S. and allied military forces launched an attack against Afghanistan (see Afghanistan War). Within months thousands of militants were killed or captured, and Taliban and al-Qaeda leaders were driven into hiding. In addition, the U.S. government exerted great effort to track down other al-Qaeda agents and sympathizers throughout the world and made combating terrorism the focus of U.S. foreign policy. Meanwhile, security measures within the United States were tightened considerably at such places as airports, government buildings, and sports venues. To help facilitate the domestic response, Congress quickly passed the USA PATRIOT Act (the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001), which significantly but temporarily expanded the search and surveillance powers of the Federal Bureau of Investigation (FBI) and other law-enforcement agencies. Additionally, a cabinet-level Department of Homeland Security was established.

Despite their success in causing widespread destruction and death, the September 11 attacks were a strategic failure for al-Qaeda. Following September 11, al-Qaeda—whose name in Arabic means “the base”—lost the best base it ever had in Afghanistan. Later some in al-Qaeda’s leadership—including those who, like Egyptian Saif al-Adel, had initially opposed the attacks—tried to spin the Western intervention in Afghanistan as a victory for al-Qaeda. Al-Adel, one of the group’s military commanders, explained in an interview four years later that the strikes on New York and Washington were part of a far-reaching and visionary plan to provoke the United States into some ill-advised actions:

Such strikes will force the person to carry out random acts and provoke him to make serious and sometimes fatal mistakes.…The first reaction was the invasion of Afghanistan.

But there is not a shred of evidence that in the weeks before September 11 al-Qaeda’s leaders made any plans for an American invasion of Afghanistan. Instead, they prepared only for possible U.S. cruise missile attacks or air strikes by evacuating their training camps. Also, the overthrow of the Taliban hardly constituted an American “mistake”—the first and only regime in the modern Muslim world that ruled according to al-Qaeda’s rigid precepts was toppled, and with it was lost an entire country that al-Qaeda had once enjoyed as a safe haven. And in the wake of the fall of the Taliban, al-Qaeda was unable to recover anything like the status it once had as a terrorist organization with considerable sway over Afghanistan.

Bin Laden disastrously misjudged the possible U.S. responses to the September 11 attacks, which he believed would take one of two forms: an eventual retreat from the Middle East along the lines of the U.S. pullout from Somalia in 1993 or another ineffectual round of cruise missile attacks similar to those that followed al-Qaeda’s bombings of American embassies in Kenya and Tanzania in 1998. Neither of these two scenarios happened. The U.S. campaign against the Taliban was conducted with pinpoint strikes from American airpower, tens of thousands of Northern Alliance forces (a loose coalition of mujahideen militias that maintained control of a small section of northern Afghanistan), and more than 300 U.S. Special Forces soldiers on the ground working with 110 officers from the Central Intelligence Agency (CIA). In November, just two months after the September 11 attacks, the Taliban fell to the Northern Alliance and the United States. Still, it was just the beginning of what would become the longest war in U.S. history, as the United States tried to prevent the return of the Taliban and their al-Qaeda allies.

In December 2001, faced with the problem of where to house prisoners as the Taliban fell, the administration decided to hold them at Guantánamo Bay, which the U.S. had been leasing from Cuba since 1903. As Secretary of Defense Donald Rumsfeld put it on December 27, 2001, “I would characterize Guantánamo Bay, Cuba, as the least worst place we could have selected.” Guantánamo was attractive to administration officials because they believed it placed the detainees outside the reach of American laws, such as the right to appeal their imprisonment, yet it was only 90 miles (145 km) off the coast of Florida, making it accessible to the various agencies that would need to travel there to extract information from what was believed to be a population of hundreds of dangerous terrorists. Eventually, some 800 prisoners would be held there, although the prison population was reduced to less than 175 by the time of the 10th anniversary of the September 11 attacks.

In his State of the Union speech on January 29, 2002, President Bush laid out a new doctrine of preemptive war, which went well beyond the long-established principle that the United States would go to war to prevent an adversary launching an attack that imminently threatened the country. Bush declared:
I will not wait on events while dangers gather. I will not stand by as peril draws closer and closer. The United States of America will not permit the world’s most dangerous regimes to threaten us with the world’s most destructive weapons.
Casus belli for the Iraq War

Casus belli for the Iraq WarThe effort to connect Iraq to the events of September 11, 2001, began within hours of the attacks. These notes, written by Department of Defense official Stephen Cambone at 2:40 pm on September 11, capture directives issued by Secretary of Defense Donald Rumsfeld. Among them is the instruction, “Best info fast. Judge whether good enough [to] hit SH [Saddam Hussein] at same time - not only UBL [Usama bin Laden].”

Bush identified those dangerous regimes as an “axis of evil” that included Iran, Iraq, and North Korea. At the graduation ceremony for West Point cadets on June 1, 2002, Bush elaborated on his preemptive war doctrine, saying to the assembled soon-to-be graduates and their families, “If we wait for threats to fully materialize, we will have waited too long.” Bush believed that there would be a “demonstration effect” in destroying Saddam Hussein’s regime in Iraq that would deter groups like al-Qaeda or indeed anyone else who might be inclined to attack the United States. Undersecretary of Defense Douglas J. Feith later explained,

What we did after 9/11 was look broadly at the international terrorist network from which the next attack on the United States might come. And we did not focus narrowly only on the people who were specifically responsible for 9/11. Our main goal was preventing the next attack.

Thus, though there was no evidence that Saddam Hussein’s government in Iraq had collaborated with al-Qaeda in the September 11 attacks, the United States prepared for conflict against Iraq in its global war against terror, broadly defined.

On March 19, 2003, on the eve of the invasion of Iraq, President Bush issued the order for war:

For the peace of the world and the benefit and freedom of the Iraqi people, I hereby give the order to execute Operation Iraqi Freedom. May God bless the troops.

On March 20 the American-led invasion of Iraq began. Within three weeks U.S. forces controlled Baghdad, and the famous pictures of the massive statue of Saddam Hussein being toppled from its plinth were broadcast around the world.

The September 11 commission and its findings

In 2002 President Bush had appointed a commission to look into the September 11 attacks, and two years later it issued its final report. The commission found that the key pre-September 11 failure at the CIA was its not adding to the State Department’s “watch list” two of the “muscle” hijackers (who were trained to restrain the passengers on the plane), the suspected al-Qaeda militants Nawaf al-Hazmi and Khalid al-Mihdhar. The CIA had been tracking Hazmi and Mihdhar since they attended a terrorist summit meeting in Kuala Lumpur, Malaysia, on January 5, 2000. The failure to watch-list the two al-Qaeda suspects with the Department of State meant that they entered the United States under their real names with ease. On January 15, 2000, 10 days after the Malaysian meeting, Hazmi and Mihdhar flew into Los Angeles. The CIA also did not alert the FBI about the identities of the suspected terrorists, which could have helped the bureau locate them once they were inside the United States. According to the commission, this was the failure of not just a few employees at the CIA but a large number of CIA officers and analysts. Some 50 to 60 CIA employees read cables about the two al-Qaeda suspects without taking any action. Some of those officers knew that one of the al-Qaeda suspects had a visa for the United States, and by May 2001 some knew that the other suspect had flown to Los Angeles.

The soon-to-be hijackers would not have been difficult to find in California if their names had been known to law enforcement. Under their real names they rented an apartment, obtained driver’s licenses, opened bank accounts, purchased a car, and took flight lessons at a local school; Mihdhar even listed his name in the local phone directory.

It was only on August 24, 2001, as a result of questions raised by a CIA officer on assignment at the FBI, that the two al-Qaeda suspects were watch-listed and their names communicated to the FBI. Even then the FBI sent out only a “Routine” notice requesting an investigation of Mihdhar. A few weeks later Hazmi and Mihdhar were two of the hijackers on the American Airlines flight that plunged into the Pentagon.

The CIA inspector general concluded that 'informing the FBI and good operational follow-through by CIA and FBI might have resulted in surveillance of both al-Mihdhar and al-Hazmi. Surveillance, in turn, would have had the potential to yield information on flight training, financing, and links to others who were complicit in the 9/11 attacks.'

The key failure at the FBI was the handling of the Zacarias Moussaoui case. Moussaoui, a French citizen of Moroccan descent, was attending flight school in the summer of 2001 in Minnesota, where he attracted attention from instructors because he had little knowledge of flying and did not behave like a typical aviation student. The flight school contacted the FBI, and on August 16 Moussaoui was arrested on a visa overstay charge. Although Moussaoui was not the '20th hijacker,' as was widely reported later, he had received money from one of the September 11 coordinators, Ramzi Binalshibh, and by his own account was going to take part in a second wave of al-Qaeda attacks following the assaults on New York and Washington.

The FBI agent in Minneapolis who handled Moussaoui’s case believed that he might have been planning to hijack a plane, and the agent was also concerned that Moussaoui had traveled to Pakistan, which was a red flag as militants often used the country as a transit point to travel to terrorist training camps in Afghanistan. On August 23 (or 24, according to some reports) CIA director George Tenet was told about the case in a briefing titled 'Islamic Extremist Learns to Fly.' But FBI headquarters determined that there was not sufficient 'probable cause' of a crime for the Minneapolis office to conduct a search of Moussaoui’s computer hard drive and belongings. Such a search would have turned up his connection to Binalshibh, according to Republican Sen. Charles Grassley, a leading member of the Senate Judiciary Committee, which has oversight of the FBI. The 9-11 Commission also concluded that “a maximum U.S. effort to investigate Moussaoui conceivably could have unearthed his connection to Binalshibh.”

The hunt for bin Laden

Joe Biden (seated left), Secretary of Defense Robert M. Gates (seated right), and Secretary of State Hillary Clinton (seated second from right)—receiving updates in the Situation Room of the White House during the Osama bin Laden mission, May 2011.

In September 2001 President Bush announced that he wanted Osama bin Laden captured—dead or alive—and a $25 million bounty was eventually issued for information leading to the killing or capture of bin Laden. Bin Laden evaded capture, however, including in December 2001, when he was tracked by U.S. forces to the mountains of Tora Bora in eastern Afghanistan. Bin Laden’s trail subsequently went cold, and he was thought to be living somewhere in the Afghanistan-Pakistan tribal regions.

U.S. intelligence eventually located him in Pakistan, living in the garrison city of Abbottabad, and in the early morning hours of May 2, 2011, on orders from U.S. Pres. Barack Obama, a small team of U.S. Navy SEALs assaulted his compound and shot and killed the al-Qaeda leader.
