9/11

The terrorist attacks of September 11, 2001, killed nearly three thousand Americans, led to two major wars, and redefined the contours of U.S. foreign policy. 

 

CFR continues to examine the legacy of 9/11, and offers selections from its archive of coverage. 

The U.S. military detention center at Guantanamo Bay, Cuba, has generated intense debate for two decades, raising enduring questions about national security, human rights, and justice.

    World Opinion on Terrorism
    This page is part of Public Opinion on Global Issues. This publication is now archived. Concern about Terrorism Concern about terrorism varies significantly around the world, with the highest levels found in the Middle East, South Asia, and Western Europe—all regions that have suffered significant terrorist attacks. Despite 9/11, Americans are only average in their level of concern.  Attitudes Toward al Qaeda and Osama bin Laden In most countries polled, a majority of the public has negative feelings about al-Qaeda, but in some countries (majority-Muslim, in most cases), these are only pluralities, and significant numbers have positive or mixed views of al-Qaeda. Worldwide, the numbers expressing positive views of Osama bin Laden have declined, but in some predominantly Muslim countries, one-fifth to one-third still express positive views toward him.  Support for Multilateral Action Against Terrorism Large majorities around the world think the UN Security Council should have the right to authorize military force to stop a country from supporting terrorist groups.  Regional Cooperation on Terrorism In North America and Europe, publics mostly give poor marks to the quality of transatlantic cooperation against terrorism. In the European Union, publics on average also give the European Union’s performance against terrorism a lukewarm assessment, while a large majority thinks more decision-making on terrorism should take place at the European level.  Assessments of U.S. Efforts against Terrorism In the struggle between the United States and al-Qaeda, the predominant view among world publics is that neither side is winning and that the “war on terror” has not weakened al-Qaeda. In recent years most have also seen the war in Iraq as increasing the likelihood of terrorist attacks around the world.  Principles for Treatment of Terrorism Suspects Majorities or pluralities in most nations reject the view that, when dealing with terrorism suspects, rules against torture and the secret holding of detainees should be relaxed. However, in several countries majorities favor making an exception when dealing with a terrorist suspect who may have information that may save innocent lives. Majorities in the United States, Britain, Germany, and Poland, and a plurality in India endorse provisions of the Geneva Conventions that forbid detainees being held in secret or without access by the International Committee of the Red Cross.  U.S. Treatment of Terrorism Suspects In 2006, majorities in Great Britain, Germany, and Poland (and a plurality in India) believed that U.S. detention policies in place at Guantanamo were illegal, whereas a slight majority of people in the United States believed they were legal. In none of the five countries—including the United States—did a majority or plurality think the United States seeks to enforce a policy against torture in interrogations. Only minorities supported allowing the United States to use their country’s airspace for rendition of a terrorist suspect to another country, if that country had a reputation for using torture.  Absence of Consensus over Who Was Behind 9/11 Attacks In seventeen countries worldwide, majorities in only nine of those countries believe al-Qaeda was behind the September 11 terrorist attacks—though in none of the other countries does a majority agree on a different possible perpetrator. Even in European countries, the majorities that say al-Qaeda was behind September 11 are not large. Publics in the Middle East are especially likely to name a different perpetrator (Israel or the United States itself).

    Sober Assessments and Missed Opportunities on Guantanamo
    CFR’s John B. Bellinger III, who served as legal adviser to the former Secretary of State Condoleezza Rice, says while President Obama has emphasized an approach to closing Guantanamo "that’s deeply grounded in American values," he has left the door open to continued criticism.

    War About Terror
    Overview President Barack Obama, in one of his first moves in office, reversed some of the most controversial detention and interrogation policies of the Bush administration. His three executive orders mandated the closure of the Guantánamo Bay detention facility within a year, and suspended both military commission proceedings and the CIA’s enhanced interrogation program. But the interagency task force established by the executive orders has a difficult task ahead: it must not only determine the future of the remaining detainees at Guantánamo, but also shed light on how to detain and interrogate future terrorist suspects in a manner consistent with American law and American values. This study finds that even if the United States successfully solves some of the most high-profile counterterrorism issues on the table, it will still lack a comprehensive, coherent, and sustainable framework for dealing with the strategic challenge posed by transnational terrorism. It argues that sharp disagreements over national security and civil liberties, as well as errors and overreach in U.S. counterterrorism practices, have stood in the way of America’s ability to forge a critical and sustainable foreign policy accord on how to address terrorist detention and trials, as well as domestic intelligence policies. The study recommends that the United States reexamine the scope and limits of its war against al-Qaeda, treating national security and the protection of individual liberties as coequal objectives. It calls on Congress and the president to engage these issues in a bipartisan fashion and craft comprehensive long-term counterterrorism policies that reaffirm the U.S. commitment to core values. Only then, it argues, will the United States be able to achieve the kind of foreign policy agreement necessary to prevail against the modern terrorist threat.
