The response of the U.S. government to the September 11 attacks sparked investigations into the motivations and execution of the attacks, as well as the ongoing War on Terrorism in Afghanistan The response included funds for affected families, plans for the War on Terrorism, rebuilding of Lower-East Manhattan, and the invasion and investigation of Iraq and Afghanistan.

Rescue, recovery, and compensationEdit

Within hours of the attack, a massive search and rescue (SAR) operation was launched, which included over 350 search and rescue dogs.[1] Initially, only a handful of wounded people were found at the site, and in the weeks that followed it became evident that there weren't any survivors to be found. Rescue and recovery efforts took months to complete. It took several weeks to simply put out the fires burning in the rubble of the buildings, and the clean-up was not completed until May, 2002. Temporary wooden "viewing platforms" were set up for tourists to view construction crews clearing out the gaping holes where the towers once stood. All of these platforms were closed on May 30, 2002.

Many relief funds were immediately set up to assist victims of the attacks, with the task of providing financial assistance to the survivors and the families of victims. By the deadline for victim's compensation, September 11, 2003, 2,833 applications had been received from the families of those killed.[2]

War on TerrorismEdit

In the aftermath of the attacks, many U.S. citizens held the view that the attacks had "changed the world forever." The Bush administration announced a war on terrorism, with the goal of bringing Osama bin Laden and al-Qaeda to justice and preventing the emergence of other terrorist networks. These goals would be accomplished by means including economic and military sanctions against states perceived as harboring terrorists and increasing global surveillance and intelligence sharing. Immediately after the September 11 attacks U.S. officials speculated on possible involvement by Saddam Hussein.[3] Although unfounded, the association contributed to public support for the 2003 invasion of Iraq. On October 7, 2001, the War in Afghanistan began when U.S and British forces initiated aerial bombing campaigns in Afghanistan targeting Taliban and Al-Qaeda camps, then later invaded Afghanistan with ground troops of the Special Forces. This was the second-largest operation of the U.S. Global War on Terrorism outside of the United States, and the largest directly connected to terrorism, resulting in the overthrow of Taliban rule in Afghanistan, by a U.S.-led coalition. The U.S. was not the only nation to increase its military readiness, with other notable examples being the Philippines and Indonesia, countries that have their own internal conflicts with Islamist terrorism.[citation needed]

Because the attacks on the United States were judged to be within the parameters of its charter, NATO declared that Article 5 of the NATO agreement was satisfied on September 12, 2001, making the US war on terrorism the first time since its inception that NATO would actually participate in a "hot" war.[4]


Following the attacks, 762 suspects were taken into custody in the United States.[5] On December 12, 2001, Fox News reported that some 60 Israelis were among them. Federal investigators were reported to have described them as part of a long-running effort to spy on American government officials. A "handful" of these Israelis were described as active Israeli military or intelligence operatives.[6]

In a letter to the editor, Ira Glaser, former head of the ACLU, claimed that none of those 762 detainees were charged with terrorism. "The Justice Department inspector general's report implies more than the violation of the civil liberties of 762 non-citizens. It also implies a dysfunctional and ineffective approach to protecting the public after Sept. 11, 2001.... No one can be made safer by arresting the wrong people".[7]

Domestic responseEdit

Immediately after opening the hunt on Osama bin Laden, President Bush also visited the Islamic Center of Washington and asked the public to view Arabs and Muslims living in the United States as American patriots.[8]

Congress passed and President Bush signed the Homeland Security Act of 2002, creating the Department of Homeland Security, representing the largest restructuring of the U.S. government in contemporary history. Congress passed the USA PATRIOT Act, stating that it would help detect and prosecute terrorism and other crimes. Civil liberties groups have criticized the PATRIOT Act, saying that it allows law enforcement to invade the privacy of citizens and eliminates judicial oversight of law-enforcement and domestic intelligence gathering. The Bush Administration also invoked 9/11 as the reason to have the National Security Agency initiate a secret operation, "to eavesdrop on telephone and e-mail communications between the United States and people overseas without a warrant."[9]

On June 6, 2002, Attorney General Ashcroft proposed regulations that would create a special registration program that required males aged 16 to 64 who were citizens of designated foreign nations resident in the U.S. to register with the Immigration and Naturalization Service (INS), have their identity verified, and be interviewed, photographed and fingerprinted. Called the National Security Entry-Exit Registration System (NSEERS), it comprised two programs, the tracking of arrivals and departures on the one hand, and voluntary registrations of those already in the U.S., known as the "call-in" program. The DOJ acted under the authority of the Immigration and Nationality Act of 1952, which had authorized a registration system but was allowed to lapse in the 1980s because of budget concerns.[10][11] Ashcroft identified those required to register as "individuals of elevated national security concern who stay in the country for more than 30 days."[12][13]

The processing of arrivals as part of their customs screening began in October 2002. It first focused on arrivals from Iran, Iraq, Libya, Sudan,and Syria.[14] It handled 127,694 people before being phased out as universal screening processes were put in place.[11]

The "call-in" registrations began in December.[14] It initially applied to nationals of five countries, Iran, Iraq, Syria, Libya and Sudan, who were required to register by December 16. On November 6, the Department of Justice set a deadline of January 10 for those from another 13 countries: Afghanistan, Algeria, Bahrain, Eritrea, Lebanon, Morocco, North Korea, Oman, Qatar, Somalia, Tunisia, the United Arab Emirates, and Yemen. On December 16, it set a deadline of February 21 for those from Armenia, Pakistan and Saudi Arabia.[15] It later included those from Egypt, Jordan, Kuwait, Indonesia, and Bangladesh.[14] It eventually included citizens of 23 nations with majority Muslim populations, as well as Eritrea, which has a large Muslim population, and North Korea.[11] Failure to register at an INS office resulted in deportation.[16] Those found in violation of their visa were allowed to post bail while processed for deportation.[11] The program registered 82,880 people, of whom 13,434 were found in violation of their visas.[11] Because nationality and Muslim affiliation are only approximations for one another, the program extended to such non-Muslims as Iranian Jews.[12] The program was phased out beginning in May 2003.[11]

Government officials pronounced the program a success. They said in the course of the combined programs, registration upon entry and that of residents, they had arrested 11 suspected terrorists, found more than 800 criminal suspects or deportable convicts, and identified more than 9,000 illegal aliens. DOJ general counsel Kris Kobach said: "I regard this as a great success. Sept. 11th awakened the country to the fact that weak immigration enforcement presents a huge vulnerability that terrorists can exploit." DOJ officials said fewer than 5% of those who came in to INS offices to register were detained.[14] James W. Ziglar, former head of INS who left the agency early in 2002, said his objections to the program were proven correct: "The people who could be identified as terrorists weren't going to show up. This project was a huge exercise and caused us to use resources in the field that could have been much better deployed."[17]

9/11 Commission Report

A federal technical building and fire safety investigation of the collapses of the Twin Towers was conducted by the United States Department of Commerce's National Institute of Standards and Technology (NIST). The goals of this investigation, completed on April 6, 2005, were to investigate the building construction, the materials used, and the technical conditions that contributed to the outcome of the WTC disaster. The investigation was to serve as the basis for:

  • Improvements in the way in which buildings are designed, constructed, maintained, and used
  • Improved tools and guidance for industry and safety officials
  • Revisions to building and fire codes, standards, and practices
  • Improved public safety

The report concludes that the fireproofing on the Twin Towers' steel infrastructures was blown off by the initial impact of the planes and that, if this had not occurred, the towers would likely have remained standing. The fires weakened the trusses supporting the floors, making the floors sag. The sagging floors pulled on the exterior steel columns to the point where exterior columns bowed inward. With the damage to the core columns, the buckling exterior columns could no longer support the buildings, causing them to collapse. In addition, the report asserts that the towers' stairwells were not adequately reinforced to provide emergency escape for people above the impact zones. NIST stated that the final report on the collapse of 7 WTC will appear in a separate report.[18]

Internal review of the CIAEdit

The Inspector General of the CIA conducted an internal review of the CIA's performance prior to 9/11, and was harshly critical of senior CIA officials for not doing everything possible to confront terrorism, including failing to stop two of the 9/11 hijackers, Nawaf al-Hazmi and Khalid al-Mihdhar, as they entered the United States and failing to share information on the two men with the FBI.[19]

9/11 Commission ReportEdit

The National Commission on Terrorist Attacks Upon the United States (9/11 Commission), chaired by former New Jersey Governor Thomas Kean, was formed in late 2002 to prepare a full and complete account of the circumstances surrounding the attacks, including preparedness for, and the immediate response to, the attacks. On July 22, 2004, the 9/11 Commission Report was released. The commission has been subject to criticism.

Civilian aircraft groundingEdit

For the first time in history, all nonemergency civilian aircraft in the United States and several other countries including Canada were immediately grounded, stranding tens of thousands of passengers across the world.[20] The order was given at 9:42 by Federal Aviation Administration Command Center national operations manager Ben Sliney. According to the 9/11 Commission Report, "This was an unprecedented order. The air traffic control system handled it with great skill, as about 4,500 commercial and general aviation aircraft soon landed without incident.[21]

Invocation of the continuity of governmentEdit

Contingency plans for the continuity of government and the evacuation of leaders were implemented almost immediately after the attacks.[20] Congress, however, was not told that the US was under a continuity of government status until February 2002.[22]
