Background information on 9-11 attacks

Despite weaknesses in preparations for disaster, failure to achieve unified incident command, and inadequate communications among responding agencies, all but approximately one hundred of the thousands of civilians who worked below the impact zone escaped, often with help from the emergency responders. At the Pentagon, while there were also problems of command and control, the emergency response was generally effective. The Incident Command System, a formalized management structure for emergency response in place in the National Capital Region, overcame the inherent complications of a response across local, state, and federal jurisdictions.

Operational Opportunities We write with the benefit and handicap of hindsight. We are mindful of the danger of being unjust to men and women who made choices in conditions of uncertainty and in circumstances over which they often had little control. Nonetheless, there were specific points of vulnerability in the plot and opportunities to disrupt it. Operational failures-opportunities that were not or could not be exploited by the organizations and systems of that time-included not watchlisting future hijackers Hazmi and Mihdhar, not trailing them after they traveled to Bangkok, and not informing the FBI about one future hijacker's U.

Defining images from the 9/11 attacks

What we can say with confidence is that none of the measures adopted by the U. Across the government, there were failures of imagination, policy, capabilities, and management. Imagination The most important failure was one of imagination. We do not believe leaders understood the gravity of the threat. The terrorist danger from Bin Ladin and al Qaeda was not a major topic for policy debate among the public, the media, or in the Congress. Indeed, it barely came up during the presidential campaign.

Al Qaeda's new brand of terrorism presented challenges to U. Though top officials all told us that they understood the danger, we believe there was uncertainty among them as to whether this was just a new and especially venomous version of the ordinary terrorist threat the United States had lived with for decades, or it was indeed radically new, posing a threat beyond any yet experienced. As late as September 4, , Richard Clarke, the White House staffer long responsible for counterterrorism policy coordination, asserted that the government had not yet made up its mind how to answer the question: "Is al Qida a big deal?

Policy Terrorism was not the overriding national security concern for the U. The policy challenges were linked to this failure of imagination. Officials in both the Clinton and Bush administrations regarded a full U. These capabilities were insufficient. Little was done to expand or reform them. The CIA also needed to improve its capability to collect intelligence from human agents. America's homeland defenders faced outward. NORAD itself was barely able to retain any alert bases at all. Its planning scenarios occasionally considered the danger of hijacked aircraft being guided to American targets, but only aircraft that were coming from overseas.

The most serious weaknesses in agency capabilities were in the domestic arena. The FBI did not have the capability to link the collective knowledge of agents in the field to national priorities.

Other domestic agencies deferred to the FBI. FAA capabilities were weak. Any serious examination of the possibility of a suicide hijacking could have suggested changes to fix glaring vulnerabilities-expanding no-fly lists, searching passengers identified by the CAPPS screening system, deploying federal air marshals domestically, hardening cockpit doors, alerting air crews to a different kind of hijacking possibility than they had been trained to expect.

Action officers should have been able to draw on all available knowledge about al Qaeda in the government. Management should have ensured that information was shared and duties were clearly assigned across agencies, and across the foreign-domestic divide.

There were also broader management issues with respect to how top leaders set priorities and allocated resources. I want no resources or people spared in this effort, either inside CIA or the Community. This episode indicates the limitations of the DCI's authority over the direction of the intelligence community, including agencies within the Department of Defense. The U. These efforts included warnings and sanctions, but they all failed. From through early , the United States pressed the United Arab Emirates, one of the Taliban's only travel and financial outlets to the outside world, to break off ties and enforce sanctions, especially those related to air travel to Afghanistan.

Saudi Arabia has been a problematic ally in combating Islamic extremism. On the other hand, government officials of Saudi Arabia at the highest levels worked closely with top U. Lack of Military Options In response to the request of policymakers, the military prepared an array of limited strike options for attacking Bin Ladin and his organization from May onward. When they briefed policymakers, the military presented both the pros and cons of those strike options and the associated risks.

Policymakers expressed frustration with the range of options presented. Following the August 20, , missile strikes on al Qaeda targets in Afghanistan and Sudan, both senior military officials and policymakers placed great emphasis on actionable intelligence as the key factor in recommending or deciding to launch military action against Bin Ladin and his organization.

  • They did not want to risk significant collateral damage, and they did not want to miss Bin Ladin and thus make the United States look weak while making Bin Ladin look strong. On three specific occasions in , intelligence was deemed credible enough to warrant planning for possible strikes to kill Bin Ladin. But in each case the strikes did not go forward, because senior policymakers did not regard the intelligence as sufficiently actionable to offset their assessment of the risks.

    The Director of Central Intelligence, policymakers, and military officials expressed frustration with the lack of actionable intelligence.

    Some officials inside the Pentagon, including those in the special forces and the counterterrorism policy office, also expressed frustration with the lack of military action. The combination of an overwhelming number of priorities, flat budgets, an outmoded structure, and bureaucratic rivalries resulted in an insufficient response to this new challenge. Many dedicated officers worked day and night for years to piece together the growing body of evidence on al Qaeda and to understand the threats.

    Yet, while there were many reports on Bin Laden and his growing al Qaeda organization, there was no comprehensive review of what the intelligence community knew and what it did not know, and what that meant.

    THE 9/11 COMMISSION REPORT

    But there were limits to what the CIA was able to achieve by disrupting terrorist activities abroad and by using proxies to try to capture Bin Ladin and his lieutenants in Afghanistan. CIA officers were aware of those limitations. To put it simply, covert action was not a silver bullet. It was important to engage proxies in Afghanistan and to build various capabilities so that if an opportunity presented itself, the CIA could act on it.

    But for more than three years, through both the late Clinton and early Bush administrations, the CIA relied on proxy forces, and there was growing frustration within the CIA's Counterterrorist Center and in the National Security Council staff with the lack of results. The development of the Predator and the push to aid the Northern Alliance were products of this frustration.

    Throughout the s, the FBI's counterterrorism efforts against international terrorist organizations included both intelligence and criminal investigations. The FBI's approach to investigations was case-specific, decentralized, and geared toward prosecution. Significant FBI resources were devoted to after-the-fact investigations of major terrorist attacks, resulting in several prosecutions. The FBI attempted several reform efforts aimed at strengthening its ability to prevent such attacks, but these reform efforts failed to implement organization-wide institutional change.

    On September 11, , the FBI was limited in several areas critical to an effective preventive counterterrorism strategy. Those working counterterrorism matters did so despite limited intelligence collection and strategic analysis capabilities, a limited capacity to share information both internally and externally, insufficient training, perceived legal barriers to sharing information, and inadequate resources.

    Permeable Borders and Immigration Controls There were opportunities for intelligence and law enforcement to exploit al Qaeda's travel vulnerabilities. Neither the State Department's consular officers nor the Immigration and Naturalization Service's inspectors and agents were ever considered full partners in a national counterterrorism effort. Permeable Aviation Security Hijackers studied publicly available materials on the aviation security system and used items that had less metal content than a handgun and were most likely permissible. Though two of the hijackers were on the U. The hijackers had to beat only one layer of security-the security checkpoint process.

    Even though several hijackers were selected for extra screening by the CAPPS system, this led only to greater scrutiny of their checked baggage. Once on board, the hijackers were faced with aircraft personnel who were trained to be nonconfrontational in the event of a hijacking. Additional expenses included travel to obtain passports and visas, travel to the United States, expenses incurred by the plot leader and facilitators outside the United States, and expenses incurred by the people selected to be hijackers who ultimately did not participate.
