Aerial view of the debris field of the North Tower, 6 WTC, and 7 WTC (upper right) World Trade Center controlled demolition conspiracy theories contend that the collapse of the World Trade Center was not caused by the airliner crash damage that occurred as part of the September 11, 2001 attacks , and the resulting fire damage, but by explosives installed in the buildings in advance. [ 1 ] Early advocates such as physicist Steven E. Jones , architect Richard Gage, software engineer Jim Hoffman , and theologian David Ray Griffin , argued that the aircraft impacts and resulting fires could not have weakened the buildings sufficiently to initiate a catastrophic collapse , and that the buildings would not have collapsed completely, nor at the speeds that they did, without additional energy involved to weaken their structures. [ citation needed ] The National Institute of Standards and Technology (NIST) and the magazine Popular Mechanics examined and rejected these theories.
Donald Rumsfeld and Rudy Giuliani at the site of the World Trade Center, on November 14, 2001. As Mayor of New York City during the September 11 attacks in 2001, Rudy Giuliani played a visible role in the response to the terrorist attack against the World Trade Center towers in New York City . For this he earned great praise at the time, but he has also become the subject of substantial criticism regarding preparedness before the attack and aspects of the response afterwards. [ edit ] Preparedness before the attacks [ edit ] Awareness of Islamic terrorism Giuliani has been criticized for ignoring the ongoing threat to New York City from Islamist terrorism in the years between the World Trade Center 1993 bombings and September 11.
This article is about 9/11 conspiracy theories . For historical discussion, see September 11 intelligence prior to the attacks . The 9/11 advance-knowledge conspiracy theories center on arguments that certain institutions or individuals other than the perpetrators had foreknowledge of the September 11 attacks .
The September 11 attacks (also referred to as September 11 , September 11th , or 9/11 ) [ nb 1 ] were a series of four coordinated terrorist attacks launched by the Islamist terrorist group al-Qaeda upon the United States in New York City and the Washington, D.C. areas on September 11, 2001. On that Tuesday morning, 19 al-Qaeda terrorists hijacked four passenger jets, intending to fly them in suicide attacks into targeted buildings. Two of those planes, American Airlines Flight 11 and United Airlines Flight 175 , were crashed into the North and South towers, respectively, of the World Trade Center complex in New York City. Both towers collapsed within two hours and falling debris, combined with fires that the debris initiated in several surrounding buildings, led to the partial or complete collapse of all the other buildings in the World Trade Center complex, also causing major damage to ten other large structures in the immediate area of the complex.

Les attentats du 11 septembre 2001 (communément appelés 11-Septembre , ou 9/11 en anglais ) sont quatre attentats-suicides perpétrés le même jour aux États-Unis , à quelques heures d'intervalle, par des membres du réseau djihadiste islamiste Al-Qaïda [ 1 ] , visant des bâtiments symboliques et faisant 2 973 victimes. Au matin du mardi 11 septembre 2001 , dix-neuf terroristes détournent quatre avions de ligne afin de les écraser sur des bâtiments hautement symboliques du nord-est du pays. Deux avions sont projetés sur les tours jumelles du World Trade Center (WTC) à Manhattan ( New York ) et un troisième sur le Pentagone , siège du Département de la Défense , à Washington, D.C. , tuant toutes les personnes à bord et de nombreuses autres travaillant dans ces immeubles.
The collapse of the two World Trade Center towers and the nearby WTC7 (in this photo, the brown building to the left of the towers) is a major focus of 9/11 conspiracy theories. 9/11 conspiracy theories are conspiracy theories that disagree with the widely accepted account that the September 11 attacks were perpetrated solely by al-Qaeda , [ 1 ] without any detailed advanced knowledge on the part of any government agency. [ 2 ] Proponents of these conspiracy theories claim there are inconsistencies in the official conclusions, or evidence which was overlooked. [ 3 ] In a 2008 global poll of 16,063 people in 17 countries, majorities in only nine countries believe al Qaeda was behind the attacks. 46% of those surveyed believed al-Qaeda was responsible for the attacks, 15% believed the U.S. government was responsible, 7% believed Israel was and another 7% believed some other perpetrator, other than al-Qaeda , was responsible.

Les théories du complot à propos des attentats du 11 septembre 2001 regroupent l'ensemble des critiques qui contestent la version officielle présentée par le gouvernement américain concernant le déroulement de ces attaques aux États-Unis . Les partisans de ces théories soutiennent que le rapport officiel n'est pas assez complet et comporterait des mensonges et des omissions. Beaucoup de ces critiques visent l' administration Bush , qui bien qu'avertie de l'imminence des attentats, aurait laissé faire les terroristes. Pour d'autres l'administration américaine aurait participé d'une manière active à ces attentats. Certaines de ces théories ont été initialement portées par le 9/11 Truth Movement , un mouvement dont se qualifient les associations ou personnes qui remettent en cause l'explication et le déroulement couramment admis des attentats.
