Reactions to the September 11 attacks

A museum panel showing headlines on September 12 in America and around the world. Most of the images on the headlines are images of United Airlines Flight 175 hitting the South Tower.

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 Biafra, 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.

Many countries introduced anti-terrorism legislation and froze the bank accounts of businesses and individuals they suspected of having connections with al-Qaeda and its leader Osama bin Laden, the perpetrators of the attacks.

In the immediate aftermath of the attacks, the Bush administration declared a war on terrorism, with the stated goals of bringing Osama bin Laden and al-Qaeda to justice and preventing the emergence of other terrorist networks. These goals were to be accomplished by means including economic and military sanctions against states perceived as harboring terrorists and increasing global surveillance and intelligence sharing. Within hours after the September 11 attacks, Defense Secretary Rumsfeld speculated on possible involvement by Saddam Hussein and ordered his aides to make plans for striking Iraq; although unfounded, the association contributed to public acceptance for the 2003 invasion of Iraq. The second-biggest operation of the US Global War on Terrorism outside of the United States, and the largest directly connected to terrorism, was the overthrow of the Taliban rule from Afghanistan, by a US-led coalition.

Muslim Americans

In a Joint Statement by the American Muslim Alliance, American Muslim Council, Association of Muslim Scientists and Engineers, Association of Muslim Social Scientists, Council on American-Islamic Relations, Islamic Medical Association of North America, Islamic Circle of North America, Islamic Society of North America, Ministry of Imam W. Deen Mohammed, Muslim American Society and Muslim Public Affairs Council, stated:

American Muslims utterly condemn the vicious and cowardly acts of terrorism against innocent civilians. We join with all Americans in calling for the swift apprehension and punishment of the perpetrators. No political cause could ever be assisted by such immoral acts.

Christian Americans

President George W. Bush, a devout Christian, quoted Psalm 23 in his Address to the Nation immediately following the attacks:

America and our friends and allies join with all those who want peace and security in the world, and we stand together to win the war against terrorism. Tonight, I ask for your prayers for all those who grieve, for the children whose worlds have been shattered, for all whose sense of safety and security has been threatened. And I pray they will be comforted by a power greater than any of us, spoken through the ages in Psalm 23: "Even though I walk through the valley of the shadow of death, I fear no evil, for You are with me."

Bush also called for solidarity with Muslims and Islam following attacks on Arab-Americans and Muslims, stating "The face of terror is not the true faith of Islam. That's not what Islam is all about. Islam is peace. These terrorists don't represent peace. They represent evil and war."

Reverend Billy Graham gave a sermon at the Washington National Cathedral for a memorial service to the victims of the terrorist attacks, declaring the need for spiritual renewal, and imploring Americans to bond together through struggle and strengthen their faith, and not to fragment and disintegrate as a people and nation.

Christian vigils, prayer services, and memorials occurred in many states across the United States.

Two days following the attacks, on the Christian television program The 700 Club, televangelist Jerry Falwell called the event a punishment from God and laid the blame on "paganists", "abortionists", "feminists" and "gays and lesbians", claiming that they "helped this happen". Host Pat Robertson concurred with the statements. Both evangelists came under attack from President George W. Bush for their statements and Falwell subsequently apologized.

Five days following the attacks, Reverend Jeremiah Wright gave a sermon at the United Trinity Church of Christ in Chicago, Illinois, claiming that the attacks were recompense for various injustices that the United States and Americans had perpetrated, before stating that now was a time for self-examination.

Leftist reactions

According to left-wing intellectuals Michael Walzer, Leo Casey, Michael Kazin, James B. Rule, and Ann Snitow, writing in Dissent, one of the responses by the American left to the September 11 attacks was to blame American actions, including the Gulf War, sanctions against Iraq, support for Saudi Arabia, and support for Israel, for provoking the September 11 attack. Walzer later described the left's response to 9/11 as a "radical failure."

Muslim and Arab World

Almost all Muslim political and religious leaders condemned the attacks. The leaders vehemently denouncing the attacks included the leaders of Egypt (Hosni Mubarak), the Palestinian Authority (Yasser Arafat), Libya (Muammar Gaddafi), Syria (Bashar al-Assad), Iran (Mohamed Khatami) and Pakistan (Pervez Musharraf). The sole exception was Iraq, when the then-president Saddam Hussein, said of the attacks that "the American cowboys are reaping the fruit of their crimes against humanity". Saddam would later offer sympathy to the Americans killed in the attacks.

In 2008, John L. Esposito and Dalia Mogahed published the findings of a six-year effort to poll and interview tens of thousands of Muslims in more than 35 countries with Muslim majorities or substantial minorities about reactions to the September 11 attacks: 23.1 percent of respondents said the attacks were in some way justified, and 7 percent viewed them as "completely justified."

• Iran: Iranian president Mohammad Khatami and Supreme Leader Ali Khamenei condemned and denounced the attacks and the terrorists who carried them out.

Huge crowds attended candlelit vigils in Iran, and 60,000 spectators observed a minute's silence at Tehran's soccer stadium. On Tuesday, September 25, in 2001, Khatami meeting British Foreign Secretary, Jack Straw, said: "Iran fully understands the feelings of the Americans about the terrorist attacks in New York and Washington on September 11." He said although the American administrations had been at best indifferent about terrorist operations in Iran (since 1979), the Iranians instead felt differently and had expressed their sympathetic feelings with bereaved Americans in the tragic incidents in the two cities." He also stated that "Nations should not be punished in place of terrorists." According to Radio Farda's website, in 2011, on the anniversary of the attacks, United States Department of State, published a post at its blog, in which the Department thanked Iranian people for their sympathy and stated that they would never forget Iranian people's kindness on those harsh days. This piece of news at Radio Farda's website also states that after the attacks' news was released, some Iranian citizens gathered in front of the Embassy of Switzerland in Tehran, which serves as the protecting power of the United States in Iran, to express their sympathy and some of them lit candles as a symbol of mourning.
• Iraq: at first justified the attacks. "The American cowboys are reaping the fruit of their crimes against humanity," said an official Iraqi statement.

Palestinian celebrations

A group of Palestinians were filmed at Damascus Gate celebrating after they had heard local news reports of attacks on the World Trade Center and the deaths of thousands of Americans. Fox News reported that in Ein el-Hilweh, Lebanon's largest Palestinian refugee camp, revelers fired weapons in the air, with similar celebratory gunfire also heard at the Rashidiyeh camp near the southern city of Tyre. Yasser Arafat and nearly all the leaders of the Palestinian National Authority (PNA) condemned the attacks. They censored and attempted to discredit broadcasts and other Palestinian news reports justifying the attacks in America, with many newspapers, magazines, websites and wire services running photographs of Palestinian public celebrations. The PNA claimed such celebrations were not representative of the sentiments of the Palestinians, and the Information Minister Yasser Abed Rabbo said the PNA would not allow "a few kids" to "smear the real face of the Palestinians". In an attempt to quell further reporting, Ahmed Abdel Rahman, Arafat's Cabinet secretary, said the Palestinian Authority could not "guarantee the life" of an Associated Press (AP) cameraman if footage he filmed of post-9/11 celebrations in Nablus was broadcast. Rahman's statement prompted a formal protest from the AP bureau chief, Dan Perry.

Arafat said of the attacks: "It's unbelievable. We completely condemn this very dangerous attack, and I convey my condolences to the American people, to the American president and to the American administration, not only in my name but on behalf of the Palestinians." He gave blood for victims of the attack in a Gaza hospital.

James Bennet reported in The New York Times that while "most" towns in the West Bank were quiet, some drivers in East Jerusalem were honking horns in celebration; he also wrote that he saw one man passing out celebratory candy. Big crowds of Palestinians celebrated in Nablus, chanting Beloved bin Laden, strike Tel Aviv! while Palestinian Authority personnel prevented photographers from taking pictures. Annette Krüger Spitta of the German public broadcaster ARD's TV magazine Panorama states that unaired footage shows the street surrounding the celebration in Jerusalem was quiet. Furthermore, she states that a man in a white T-shirt incited the children and gathered people together for the shot. The Panorama report, dated September 20, 2001, quotes Communications Professor Martin Löffelholz explaining that in the images one sees jubilant Palestinian children and several adults, but there is no indication that their pleasure is related to the attack. The woman seen cheering stated afterwards that she was offered cake if she celebrated on camera, and was frightened when she saw the pictures on television afterward.

There was also a rumour that the footage of some Palestinians celebrating the attacks was stock footage of Palestinian reactions to the Iraqi invasion of Kuwait in 1990. This rumour was proven false shortly afterwards, with CNN and Reuters issuing a statement to that effect. A poll of Palestinians conducted by the Fafo Foundation in 2005 found that 65% of respondents supported "Al Qaeda bombings in the USA and Europe".

• Ahmed Yassin, the spiritual leader of Hamas, stated: "We are not ready to move our struggle outside the occupied Palestinian land. We are not prepared to open international fronts, however much we criticize the unfair American position." Yassin also stated: "No doubt this is a result of injustice the U.S practices against the weak in the world."

Polls taken several years later by Saudi-owned Al Arabiya and Gallup suggest some support for the September 11 attacks within the Islamic world, with 38% believing the attacks to be not justified, while 36% believing them to be justified when Saudis were polled in 2011. Another 2008 study, produced by Gallup, found that 7% of the sample of Muslims polled believing the 9/11 attacks were "completely" justified.
