What caused the September 11 attacks?

The attacks were a deliberate attempt by a terrorist organization (al-Qaeda) to affect the foreign policy of the US and other nations by killing civilians in a series of organized suicide attacks. The underlying reasons for the attacks are a subject of continued debate.

  • A brief answer is that the United States has garnered a lot of hostility because of its support for the establishment and continuation of Israel, a Jewish state. This support has angered many Islamic nations in that geographic region, leading to many radical Islamic fundamentalists calling on the United States to withdraw from the region altogether and to stop supporting Israel. Obviously, the strategic interests for energy are too important for the United States to do this, and so the people -- Islamic fundamentalists believing they have a religious duty to fight the United States' infidels -- call on followers of radical Islamic faith to make war on US citizens and the US government.
  • In addition to Israel, Bin Laden himself listed several other grievances including, but not limited to: US soldiers stationed in Arabia in violation of Mohammed's wish that Arabia be entirely Muslim, the US and Australian intervention to assist East Timor (a majority-Christian country) to gain independence from Indonesia (a majority-Muslim country), the US intervention in Iraq in the Gulf War of 1990-1991 that resulted in Kuwait's freedom and the death of many Iraqis as well as no fly zones in Iraq, and the US support and direction of the Egyptian Regime under Hosni Mubarak.
  • The hijackers were mostly citizens of Saudi Arabia and they were thought to be members of Al Qaeda, led by Osama Bin Laden. A group of terrorists took control of two commercial airliners and purposely crashed them into the "twin towers" of the World Trade Center on Sept. 11, 2001. Another group of terrorists took control of another commercial airliner, reportedly headed for the White House in Washington, D.C., which crashed in a field in Pennsylvania after the terrorists were overtaken by a group of passengers. Another group of terrorists took control of yet another airliner and purposely crashed it into the Pentagon.
  • It is generally believed that the Koran's teachings engender in some Muslim fundamentalists a hate for westerners which caused them to commit these hostile, mass-murdering terrorist acts. The terrorists believed that giving their lives in order to kill many of their western 'infidel enemies' in the United States was a "holy" act given to them by their god. They felt it was what they were 'destined to do' for their god, and that's why they did it.
  • Muslim fanatics attacked the US because of their belief that predominantly Christian nations such as the US have deprived the Islamic world of the leading role, and the power and prestige that it rightfully deserves. Elements of Christianity and Islam have been in conflict since the Muslim conquest of the Levant, North Africa and the Iberian Peninsula (beginning in the seventh century) and the Crusades in the eleventh, twelfth, and thirteenth centuries. Additionally, US support for the nation of Israel since 1948 has greatly inflamed Muslim resentment toward the US. To the September 11th terrorists, that attack was merely the latest battle in a long running war between faiths.
  • Also, be aware that there are many people who simply hate the United States because they have a distorted view of our country. Instead of seeing the United States as the "melting pot" country that it is; that it is a "free" country; that it allows its people to believe, speak, and worship as they wish. They prefer to believe that because Americans do not believe, speak, and worship as they do, that everyone here is full of sin, going against "their" God in so many ways (religion, technology, etc.); not living our lives in their simple and prudent ways; not using only what is necessary, but rather using more than our share.
  • Additionally, there are many people in the West, including the U.S., who have historically viewed the Islamic nations as nothing more than a source of wealth to be exploited, with no regard for the welfare of the area's populace.

Extreme religious views, and a total disregard for the rights and freedoms of others caused 9-11, and led terrorists to attack a nation because of a lack of tolerance for differences.

The September 11, 2001 attacks on the United State of America was caused by terrorists affiliated with Al-Qaeda, the extremist Sunni Islamist militant group founded by, now deceased, Osama bin Laden. There motivation was repeatedly broadcast in recorded televised message in which they had declared a "Jihad" (so-called "struggle on behalf of God") on the United States, and had vowed death to Americans.

Their extremist religious beliefs convince them that the doctrine contained in the Qur'an teaches that anyone who does not live according to their strict standards, and those who do not believe as they do are "infidels" and "non-believers," and must be killed. Since the American way of life promotes democracy, free will, free speech, free religion, and a number of other freedoms pertaining to potentially deviant behavior, Americans are viewed as "infidels" and their way of life is a threat to the extremist Islamist. They believe that "Allah" commands them to kill infidels, and rewards them in Heaven if they die in the process. Suicide bombings and hijackings are believed by these extremists as a guaranteed reward in the after-life.

There is an official explanation that holds the terrorist organization Al-Qaeda and its founder and leader Osama bin Laden were responsible for the attacks. In the words of George W. Bush: "They hate us because of our freedom."
The terrorist attacks of 9/11 were started when tensions between powerful groups in middle east and the United States reached a breaking point. Al Qaeda was supposedly formed as a militant group around the time of the Desert Storm conflict between Iraq and the U.S. They have been blamed for many attacks in Iraq and Afghanistan before they infiltrated many factions of US security including the military and the CIA in order to find weaknesses in America's defenses in preparation of four large scale attacks using large commercial airplane, three of which were very successful and one was supposedly thwarted by hijacked passengers, missing it's target but nonetheless crashed in rural Pennsylvania, adding to the casualties.
Terrorist groups wished to kill hundreds or, if they could, thousands of innocent Americans. This is what extreme religion does to you...most Muslims are very peaceful, just like Christians or Catholics or Jews, but these extremists are dangerous and insane. They decided to kill the "infidels," or those who don't believe like they do.
