The September 11 attacks transformed the first term of President George W. Bush and led to what he referred to as the war on terror. The accuracy of describing it as a "war" and its political motivations and consequences are the topic of strenuous debate. The U.S. government increased military operations, economic measures, and political pressure on groups that it accused of being terrorists, as well as increasing pressure on the governments and countries which were accused of sheltering them. October 2001 saw the first military action initiated by the US. Under this policy, NATO invaded Afghanistan to remove the Taliban regime (which harbored al-Qaeda) and capture al-Qaeda forces.
Critics point out that the Afghan conflict has contributed to the destabilization of neighbouring Pakistan [1] and Afghanistan has undergone a long war, culminating in the return of the Taliban in 2021. The US government has also asserted that the US invasion of Iraq is connected to 9/11. [2]
Because of the events that took place on September 11, 2001, American society as a whole suffered dramatically. Recovery took years, and the economy declined drastically after the attacks. Various first responders united that day to help as much as possible. Whether they were paramedics, police officers, firefighters, doctors, nurses, or ordinary civilians, the main objective was to cooperate and help the wounded. More than 1,500 first responders, ironworkers, engineers, heavy equipment operators, and other workers worked at Ground Zero to attempt to find survivors and clean up the wreckage. [3] Cranes and bulldozers were brought in along with search and rescue dogs [4] in order to locate survivors and bodies of the deceased, however, operations were hindered by the presence of approximately two feet of soot at the site, which obscured objects and bodies. [5]
In the immediate aftermath of the attacks, only 20 survivors were pulled alive from the rubble, [6] although there were several human remains and belongings that were removed from the site. The day after the attack, then-mayor Rudy Giuliani told reporters that they were receiving mobile phone calls from people trapped in the debris. [5] The task of removing debris and rubble continued well into 2002, with some 108,000 truckloads of 1.8 million tons of rubble removed by May 2002. [7]
Outside of the general hazards due to fires, falling debris, heavy machinery, broken metal, and hazardous air conditions, there were also hidden concerns within the clean-up zone. The parking garage under the World Trade Center at the time of the attacks held nearly 2,000 automobiles; each held an estimated 5 gallons of gasoline, which could ignite and explode. Other concerns were around buried fuel tanks that were located on the site, and the 1.2 million rounds of ammunition that were housed at Building 6 for the use of the U.S. Customs Service. [8]
Following the September 11, 2001 attacks, George W. Bush's job approval rating soared to 86%. [9] On September 20, 2001, the president spoke before the nation and a joint-session of Congress, regarding the events of that day, the intervening nine days of rescue and recovery efforts, and his intent in response to those events in going after the terrorists who orchestrated the attacks. In the speech, he characterized the speech itself as being akin to the President's customary State of the Union address.
The attacks also had immediate and overwhelming effects upon the United States population. People began rallying around the popularized phrase, "United We Stand," in hopes of being resilient and keeping the American spirit alive in the face of a devastating attack. The majority of the US population rallied behind President Bush and the federal government in widespread support to the recovery and the expectant reaction to the attacks. The highly visible role played by Rudy Giuliani, the Mayor of New York City, won him high praise nationally and in New York City. [10] He was named Person of the Year by Time magazine for 2001, and at times had a higher profile in the US than President Bush.
Two major public reactions to the attacks were a surge of public expressions of patriotism not seen since World War II, marked most often by displays of the American flag; and an unprecedented level of respect, sympathy, and admiration for New York City and New Yorkers as a group by Americans in other parts of the United States. Some criticized this particular reaction, noting that not everyone who died was from New York City (for example, some of the passengers on the planes) and that the Arlington County, Virginia community also suffered in the attacks. Many people joined together to help the victims. Gratitude toward uniformed public-safety workers, and especially toward firefighters, was widely expressed in light of both the drama of the risks taken on the scene and the high death toll among the workers. Many people paid tribute to the police officers and firefighters who died during the attacks by wearing NYPD and FDNY hats. The number of casualties among the emergency service personnel was unprecedented.
Blood donations saw a surge in the weeks after 9/11. According to a report by the Journal of the American Medical Association, "...the number of blood donations in the weeks after September 11, 2001, attacks was markedly greater than in the corresponding weeks of 2000 (2.5 times greater in the first week after the attacks; 1.3–1.4 times greater in the second to fourth weeks after the attack)." [11] At the Westminster Kennel Club Dog Show that took place in New York in February 2002, a tribute was paid to the search and rescue dogs who not only assisted in locating survivors and bodies from the rubble but were also inside the World Trade Center buildings before they collapsed.
In weeks following the attacks, there was a surge in incidents of harassment and hate crimes against South Asians, Middle Easterners, and anyone thought to be "Middle Eastern-looking" people—particularly Sikhs, because Sikh males usually wear turbans, which are stereotypically and erroneously associated with Muslims by many Americans. Balbir Singh Sodhi, a Sikh man, was one of the first victims of this backlash; he was shot dead on September 15 at the gas station he owned in Mesa, Arizona. Mark Anthony Stroman, a white supremacist, killed two men and injured a third in a shooting spree beginning September 15 in Dallas, Texas. His victims, including Bangladeshi American Rais Bhuiyan, were all targeted because they looked "of Muslim descent". His motive for the killings was revenge for the 9/11 attacks. On July 20, 2011, Stroman was executed for the crime. [12]
In many cities there were reports of vandalism against mosques and other Islamic institutions, including some cases of arson. [13] [14] [15] [16] In the year after the attack, anti-Muslim hate crimes jumped 1,600 percent and this is further aggravated by a climate of prejudice that manifests in different ways. [17]
The only death officially recorded as a homicide in New York City on September 11 was Henryk Siwiak, a Polish immigrant who was shot in Bedford-Stuyvesant, Brooklyn. While he had taken a wrong turn on his way to a new job onto a street known for high rates of robbery and drug dealing, his family has theorized he may have been the victim of a hate crime in the wake of the attacks, since he was wearing camouflage clothing, had dark hair and spoke imperfect, heavily accented English—all of which may have led someone to believe he had something to do with the attackers. [18] The case remains unsolved; police are open to the family's theory but have not classified the killing as a bias crime. [19]
In 2008, author Moustafa Bayoumi released the book How Does It Feel to Be a Problem?: Being Young and Arab in America. [20] The author says mass arrests and deportations of Arabs and Arab Americans were conducted by the various government organizations, including the FBI, often with insufficient evidence to connect them to terrorism; that some were incarcerated indefinitely without notifying the detainee's relatives as if they had just disappeared. Bayoumi maintains deportation of Arabs and Arab-Americans significantly increased following 9/11, often at short notice, saying in one case a man was deported without his clothes.
The attacks were regarded by some as particularly disturbing to children, in part because of the frequency with which the images were replayed on television. Many schools closed early, especially those with children whose parents worked in Washington, D.C., and New York City. In Sarasota, Florida, Emma E. Booker Elementary School became a part of history, as President George W. Bush was reading to a classroom of children there when the attacks happened. [21]
Psychological studies focused on children exposed to the attacks in Lower Manhattan and New York City found higher rates of clinically significant behavior problems among preschool children, as well as elevated rates of PTSD and depression in the years after the attacks. [22] For children who lost a parent in the attack, psychologists noticed that while some coped well initially, they would at times succumb to bouts of depression and self-harm later in life, or become reluctant to discuss their family history. [23]
The thousands of tons of toxic debris resulting from the collapse of the Twin Towers contained more than 2,500 contaminants, including known carcinogens. [24] [25] Subsequent debilitating illnesses among rescue and recovery workers are said to be linked to exposure to these carcinogens. [26] [27] The Bush administration ordered the Environmental Protection Agency (EPA) to issue reassuring statements regarding air quality in the aftermath of the attacks, citing national security; however, the EPA did not determine that air quality had returned to pre-September 11 levels until June 2002. [28]
Health effects also extended to residents, students, and office workers of Lower Manhattan and nearby Chinatown. [29] Several deaths have been linked to the toxic dust, and the victims' names were included in the World Trade Center memorial. [30] As of January 1, 2002, the New York Police Department had received 37 disability claims, and the Fire Department reported 269 disability claims related to injuries suffered as a result of the attacks. [31] Approximately 18,000 people have been estimated to have developed illnesses as a result of the toxic dust. [32] By 2004, nearly half of more than 1,000 screened rescue-and-recovery workers and volunteers reported new and persistent respiratory problems, and more than half reported persistent psychological symptoms. [33] Because of the long latency period between exposure and development of asbestos-related diseases, exposed Manhattan residents, especially rescue-and-recovery workers, can suffer future adverse health effects. One such death related to health effects was the January 6, 2006, death of NYPD James Zadroga which was ruled by a New Jersey coroner as directly due to clean-up at the WTC site. [34] This ruling was unequivocally rejected in October 2007 by the New York City Chief Medical Examiner, Dr. Charles Hirsch, and Medical Examiner Michele Slone. [35] On June 29, 2019, former New York Police Department detective Luis G. Alvarez died from colorectal cancer, with which he was diagnosed in 2016 and is believed to be caused from his three months spent at Ground Zero after 9/11. [36] [37]
There is also scientific speculation that exposure to various toxic products in the air may have negative effects on fetal development. A notable children's environmental health center is currently analyzing the children whose mothers were pregnant during the WTC collapse and were living or working nearby. [38] A study of rescue workers released in April 2010 found that all those studied had impaired lung functions, and that 30–40% were reporting little or no improvement in persistent symptoms that started within the first year of the attack. [39]
Years after the attacks, legal disputes over the costs of illnesses related to the attacks were still in the court system. On October 17, 2006, a federal judge rejected New York City's refusal to pay for health costs for rescue workers, allowing for the possibility of numerous suits against the city. [40] Government officials have been faulted for urging the public to return to lower Manhattan in the weeks shortly after the attacks. Christine Todd Whitman, administrator of the EPA in the aftermath of the attacks, was heavily criticized by a U.S. District Judge for incorrectly saying that the area was environmentally safe. [41] Mayor Giuliani was criticized for urging financial industry personnel to return quickly to the greater Wall Street area. [42]
After the terrorist attack, various repercussions took place that affected the U.S as a whole. All the money and claims that were being put out to help aid the victims of the attack, as well as different security and laws to protect the U.S, caused several layoffs and unemployment. Specifically, It was said that 462 extended masses were layoffs because of the attacks that displaced approximately 130,000 employees. [43] The unemployment rate inclined to a total of 5.0%.
The attacks caused an estimated overall economic loss to the city of $82.8 to 94.8 billion, with the lower number being consistent with the NYC Partnership's November 2001 estimate and the high end being consistent with the New York City Comptroller's October 2001 estimate. [31] It was calculated that the lost human productive value, life insurance payouts were $2.63 billion, federal payments after offsets were estimated at $2.34 billion and charitable payments were $0.79 billion. [31]
It was projected by one individual that the public art that was damaged or destroyed during the attacks was valued at $10 million. Art by Louise Nevelson, Alexander Calder, and James Rosati were all destroyed along with a memorial sculpture by Elyn Zimmerman in memorial for the victims of the 1993 World Trade Center Bombing. [44]
As of August 2002, there were approximately 1,464 claims against the city of New York City that amounted to approximately $8.2 billion, although the New York City Law Department indicated at the time that the City's liability for the claims would only be around $350 million, provided through an act of Congress. The claims ranged from City employee's personal injuries that totaled around $5.2 billion, suffering due to the loss of life that totaled around $3 billion, and for the destruction of property such as the one filed by AEGIS Insurance Company for $250 million. [31]
Following the road to recovery, the federal government and state begin issuing grants and various funds to compensate and help those who suffered. The 9/11 Heroes Stamp Program was administered by the Department of Homeland Security which gave funds to those who became disabled from direct contact in the attack or suffered a loss from the attack. [45] The Post- 9/11 GI Bill became a result after 9/11, paying homage to the U.S military soldiers, which provided educational and financial assistance to those soldiers who were returning to civilian life. [45] Federal grant aid assisted states, communities, and local organizations in their efforts to stay safe and remain readily prepared. [45] For that to happen the program law enforcement training and technical assistance grant was created hoping to stop or better compose for a terrorist attack.
The September 11th Victim Compensation fund (VCF) was established to provide financial assistance to those that experienced the disaster directly or those who lost family members from the attack. [46] The fund has provided reimbursements for medical treatments for various conditions affecting victims, including PTSD and health effects from being exposed to toxic air.
The attacks affected trade relations with foreign countries, complicating the supply of oil demands. After the attack, oil prices skyrocketed. [43]
Rebuilding of the area began shortly after clean up, and construction began on the Freedom Tower and the National September 11 Memorial and Museum. [7]
Park51 (originally named Cordoba House) is a planned 13-story Muslim community center to be located two blocks from the World Trade Center site [47] [48] in Lower Manhattan. The majority of the center will be open to the general public and its proponents have said the center will promote interfaith dialogue. It will contain a Muslim prayer space that has controversially [49] [50] been referred to as the "Ground Zero mosque", though numerous commentators noted that it was neither a mosque nor at Ground Zero.
It would replace an existing 1850s Italianate-style building that was being used as a Burlington Coat Factory before it was damaged in the September 11 attacks. The proposed multi-faith aspects of the design include a 500-seat auditorium, theater, a performing arts center, a fitness center, a swimming pool, a basketball court, a childcare area, a bookstore, a culinary school, an art studio, a food court, and a memorial to the victims of the September 11 attacks. The prayer space for the Muslim community will accommodate 1,000–2,000 people. [47] [51]

The evolution of security and protective services changed tremendously due to the attacks. Immediate changes included air travel policies, airport security and screening, and guidelines that must be obeyed before getting on board. Congress immediately responded after the terrorist attack by passing the Aviation and Transportation Security Act, [52] which applied to different types of transportation, not just air travel.
Additional screening was another main focus that took place during the period after the attacks, and many passengers were prescreened and advanced screened at different security checkpoints. This led to the major issue of racial profiling and invasion of privacy, as many Middle Eastern-looking people were singled out for further screening. Luggage screening was another main objective, as new technology was introduced to scan passengers' luggage thoroughly and search for weapons or bombs. In addition, some pilots were required by the Department of Homeland Security to carry a firearm on board. Better known as a Federal flight deck officer, these pilots undergo training to prevent terrorist attacks or other potential dangers on an airplane.
Another act was passed known as the USA Patriot Act, which broadened the powers of law enforcement to identify terrorist activity. For example, law enforcement was allowed able to break one's premises without a search warrant and their consent, if they were suspected of terrorist activity. This also included roving wiretaps as a method of surveillance. For instance, the government was allowed to search through one's record searches and intelligence searches. Specifically, if one searched terrorism activities or showed unusual behavior and then deleted their history, the government was able to see that. The purpose of this act was to catch acts of terrorism before any attacks were planned and executed. A program called Total Information Awareness was developed to enhance the technology that would collect and analyze information about every individual in the United States, and trace unusual behaviors that could help prevent terrorist activities. Information that was gathered through the program included internet activity, credit card purchase histories, airline ticket purchases, and medical records.
Bombings in Kabul, Afghanistan occurred after the attacks and were reposted live by CNN correspondent Nic Robertson less than 24 hours after the attacks in America. [56]
The attacks had major worldwide political effects. Many other countries introduced tough anti-terrorism legislation and took action to cut off terrorist finances, including the freezing of bank accounts suspected of being used to fund terrorism. Law enforcement and intelligence agencies stepped up cooperation to arrest terrorist suspects and break up suspected terrorist cells around the world.
Reaction to the attacks in the Muslim world was mixed. Also, shortly after the attack, the media picked up on several celebrations of the attacks in the Middle East with images of these celebrations being broadcast on television and published in print. Less publicized were public displays of sympathy, including candlelight vigils in countries like Iran. [57]
In the immediate aftermath, support for the United States' right to defend itself was expressed across the world, and by United Nations Security Council Resolution 1368. [58] The Australian Prime Minister, John Howard, was in Washington D.C. at the time of the attacks and invoked the ANZUS military alliance as a pledge of Australian assistance to the U.S.
In the immediate aftermath of the attacks many United States–based airports would not accept airplane flights to land, causing Operation Yellow Ribbon in which all incoming international flights were rerouted by the FAA to airports in Canada. [59] Many Canadians opened up their homes to stranded travelers and organizations such as the Society for the Prevention of Cruelty to Animals gave comfort to animals and other special groups that were stranded by the diversions. [60]
In France, calls to the United States Embassy were placed by locals who offered rooms within their homes to stranded passengers and observed the official day of mourning with three minutes of silence and stillness. [61]
The attack prompted numerous memorials and services all over the world with many countries, along with the United States, declaring a national day of mourning. In Berlin, 200,000 Germans marched to show their solidarity with America.[ citation needed ] The French newspaper of record, Le Monde , ran a front-page headline reading "Nous sommes Tous Américains", or "We are all Americans". [62] In London, the US national anthem was played at the Changing of the Guard at Buckingham Palace. [63] In the UK, national anthems are typically only played for official state visits. To mark the Queen's Golden Jubilee, New York City lit the Empire State Building in purple and gold, to say "thank you" for this action.[ citation needed ]
Hate crimes against Muslims increased around the world. For example, Canada experienced a 16-fold increase in anti-Muslim attacks immediately a year after 9/11. [64] In the year leading to the attack, there were only 11 reported crimes but a year following 9/11, there were 173 hate crime cases reported. [64] The same also happened in the United Kingdom and Australia. In the latter's case, a study conducted in Sydney and Melbourne revealed an overwhelming majority of Muslim residents who experienced racism or racist violence since the attack. [64] Another study claimed that hate crimes "increased for all Muslims after 9/11, although the relative risk was much higher for those individuals living in countries with smaller Muslim populations." [65]
An increase in racial tensions was seen in countries such as England, with a number of violent crimes linked to the September 11th attacks. [66] The most severe example was seen in Peterborough, where teenager Ross Parker was murdered by a gang of up to ten Muslims of Pakistani background who had sought a white male to attack. [67] [68] [69] [70]
After the September 11, 2001 attacks, the United States government responded by commencing immediate rescue operations at the World Trade Center site, grounding civilian aircraft, and beginning a long-term response that included official investigations, legislative changes, military action, and restoration projects.
The September 11 attacks of 2001 were a major event that had a significant long-lasting impact even beyond the day of the attacks itself. This article summarizes events which relate to the attacks in the remaining days of September 2001. News coverage was significant in the period after the attacks which meant that many of these events were reported on quickly by news agencies at the time.
Terrorism, in its broadest sense, is the use of violence against non-combatants to achieve political or ideological aims. The term is used in this regard primarily to refer to intentional violence during peacetime or in the context of war against non-combatants. There are various different definitions of terrorism, with no universal agreement about it. Different definitions of terrorism emphasize its randomness, its aim to instill fear, and its broader impact beyond its immediate victims.
John Patrick O'Neill was an American counter-terrorism expert who worked as a special agent and eventually a special agent in charge in the Federal Bureau of Investigation. In 1995, O'Neill began to intensely study the roots of the 1993 World Trade Center bombing after he assisted in the capture of Ramzi Yousef, who was the leader of that plot.
Nuclear terrorism refers to any person or persons detonating a nuclear weapon as an act of terrorism. Nuclear terrorism outlines a broad category of possible terror incidents, ranging in feasibility and scope. Possible methods include the sabotage of a nuclear facility, the intentional irradiation of citizens, and/or the detonation of a radiological device, colloquially termed a dirty bomb, but consensus is lacking. According to the 2005 United Nations International Convention for the Suppression of Acts of Nuclear Terrorism. nuclear terrorism is an offense committed if a person unlawfully and intentionally "uses in any way radioactive material … with the intent to cause death or serious bodily injury; or with the intent to cause substantial damage to property or to the environment; or with the intent to compel a natural or legal person, an international organization or a State to do or refrain from doing an act."
The 9/11 Commission Report, officially the Final Report of the National Commission on Terrorist Attacks Upon the United States, is the official report into the events leading up to the September 11, 2001 terrorist attacks. It was prepared by the 9/11 Commission, chaired by former New Jersey governor Thomas Kean, at the request of U.S. President George W. Bush and Congress.
The post-9/11 period is the time after the September 11 attacks, characterized by heightened suspicion of non-Americans in the United States, increased government efforts to address terrorism, and a more aggressive American foreign policy.
The September 11 attacks, commonly known as 9/11, were four coordinated Islamist terrorist suicide attacks carried out by al-Qaeda against the United States in 2001. Nineteen terrorists hijacked four commercial airliners, crashing the first two into the Twin Towers of the World Trade Center in New York City and the third into the Pentagon in Arlington County, Virginia. The fourth plane crashed in rural Pennsylvania during a passenger revolt. The September 11 attacks killed 2,977 people, making it the deadliest terrorist attack in history. In response to the attacks, the United States waged the multi-decade global war on terror to eliminate hostile groups deemed terrorist organizations, as well as the foreign governments purported to support them.
The 2002 State of the Union Address was given by the 43rd president of the United States, George W. Bush, on January 29, 2002, at 9:00 p.m. EST, in the chamber of the United States House of Representatives to the 107th United States Congress. It was Bush's first State of the Union Address and his second speech to a joint session of the United States Congress. Presiding over this joint session was the House speaker, Dennis Hastert, accompanied by Dick Cheney, the vice president, in his capacity as the president of the Senate.
The war on terror, officially the Global War on Terrorism (GWOT), is a global military campaign initiated by the United States following the September 11 attacks in 2001, and is the most recent global conflict spanning multiple wars. Some researchers and political scientists have argued that it replaced the Cold War.
In the United States, a common definition of terrorism is the systematic or threatened use of violence in order to create a general climate of fear to intimidate a population or government and thereby effect political, religious, or ideological change. This article serves as a list and a compilation of acts of terrorism, attempts to commit acts of terrorism, and other such items which pertain to terrorist activities which are engaged in by non-state actors or spies who are acting in the interests of state actors or persons who are acting without the approval of foreign governments within the domestic borders of the United States.
Reactions to the 2008 Mumbai attacks were on the local, national and international levels. Political reactions in Mumbai and throughout India included a range of resignations and political changes. Other reactions included condemnation of the attacks by an Indian Muslim organisation and Naxalites. International reactions to the attacks was widespread, with many countries and international organisations condemning the attacks and expressing their condolences to the civilian victims. Media coverage highlighted the use of new media and internet social-networking tools in spreading information about the attacks, observing that internet coverage was often faster than more-traditional media sources.
The September 11 attacks were condemned by world leaders and other political and religious representatives and the international media, as well as numerous memorials and services all over the world. The attacks were widely condemned by world governments, including those traditionally considered hostile to the United States, such as Cuba, Iran, Syria, Libya, North Korea, and Afghanistan itself. However, in a few cases celebrations of the attacks were also reported, and some groups and individuals accused the United States in effect of bringing the attacks on itself. These reports have been uncorroborated and many have been linked to unsubstantiated conspiracy theories.
Talat Hamdani is a Pakistan-born American who became a commentator after her son was killed during Al Qaeda's attacks on September 11, 2001. Her eldest son, Mohammad Salman Hamdani, was a New York Police Department cadet, who had trained as a first responder.
The September 11 attacks were carried out by 19 hijackers of the Islamist militant organization al-Qaeda. In the 1990s, al-Qaeda leader Osama bin Laden declared a militant jihad against the United States, and issued two fatawa in 1996 and 1998. In the 1996 fatwa, he quoted the Sword Verse. In both of these fatawa, bin Laden sharply criticized the financial contributions of the American government to the Saudi royal family as well as American military intervention in the Arab world.
At around 9:30 pm on September 11, 2001, George Tenet, director of the Central Intelligence Agency (CIA), told President George W. Bush and U.S. senior officials that the CIA's Counterterrorism Center had determined that Osama bin Laden and al-Qaeda were responsible for the September 11 attacks. Two weeks after the terrorist attacks on September 11, 2001, the Federal Bureau of Investigation connected the hijackers to al-Qaeda, a militant Salafist Islamist multi-national organization. In a number of video, audio, interview and printed statements, senior members of al-Qaeda have also asserted responsibility for organizing the September 11 attacks.
The following outline is provided as an overview of and topical guide to the September 11 attacks and their consequences:
Islamic extremism in the United States comprises all forms of Islamic extremism occurring within the United States. Islamic extremism is an adherence to fundamentalist interpretations of Islam, potentially including the promotion of violence to achieve political goals. In the aftermath of the September 11, 2001 terror attacks, Islamic extremism became a prioritized national security concern of the U.S. government and a focus of many subsidiary security and law enforcement entities. Initially, the focus of concern was on foreign Islamic terrorist organizations, particularly al-Qaeda, but in the course of the years since the September 11 terror attacks, the focus has shifted more towards Islamic extremist radicalized individuals and jihadist networks within the United States.
The 1993 World Trade Center bombing was a terrorist attack carried out by Al-Qaeda against the United States on February 26, 1993, when a van bomb detonated below the North Tower of the World Trade Center complex in Manhattan, New York City. The 1,336 lb (606 kg) urea nitrate–hydrogen gas enhanced device was intended to make the North Tower collapse onto the South Tower, taking down both skyscrapers and killing tens of thousands of people. While it failed to do so, it killed six people, including a pregnant woman, and caused over a thousand injuries. About 50,000 people were evacuated from the buildings that day.
The cultural influence of the September 11 attacks (9/11) was profound and lasted nearly two decades. The impact of 9/11 extended well beyond geopolitics, spilling into society and culture in general. Many Americans began to identify a "pre-9/11" world and a "post-9/11" world as a way of viewing modern history. This created the feeling that the attacks put an end the peacetime prosperity that dominated American life up to that point. Prominent social issues at the time, such as the public discourse in the wake of the Columbine High School massacre, became overshadowed by the attacks. Following 9/11, the attention of most Americans shifted from domestic issues towards terrorism abroad.
