9/11 conspiracy theories
9/11 conspiracy theories are claims that the September 11, 2001 attacks did not happen in the way they are traditionally thought to have happened. Most theories state that, in one way or another, the United States government attacked its own country, or knew about the attack ahead of time and decided to let it happen.
The evidence provided by the conspiracy theorists, also known as Truthers or "9/11 truthers" has been widely debunked by many famous researchers and even some 9/11 sympathizers. Some information about specific theories is provided here. Likewise, the evidence provided by the United States government, has been widely debunked by many famous researchers and even some 9/11 sympathizers.
7 World Trade Center (WTC-7)
There are claims that WTC-7 was brought down by controlled demolition on 9/11.
Some quote an owner of WTC-7 (Larry Silverstein) as saying they demolished the building. These people say that when he said in an interview that they decided to "pull" the building, he meant demolish.
The BBC television coverage is often cited for WTC-7-related conspiracy theories, as it reports WTC-7's collapse before it actually happened. WTTG (Washington DC's Fox affiliate) also makes this mistake. Coverage from CNN used the phrase "may collapse".
The BBC's official explanation was that the fire authorities expected the collapse, and claims the press was informed of this, which would support the CNN account.
Black smoke was seen coming out of WTC-7 and other places on 9/11. A common conspiracy theory says that black smoke means that a fire is starved of oxygen, and therefore can easily be put out. It is said that the firefighters did not attempt to put out the fire, in this case. There was a large amount of diesel fuel in Building 7, which was used for running backup diesel generators in case of a power outage. Also, all three buildings contained large amounts of plastics, which can also burn very hot and be difficult to put out, yet give off dark-colored (and highly toxic) smoke.
Past statements by prominent Bush Administration figures
Many cite quotes from a document called "Rebuilding America's Defenses", released by the Project for the New American Century, a think tank featuring many prominent Bush Administration figures.
The document, written in September 2000, was a reaction to then-President Bill Clinton's post-Cold-War military funding cuts. As many neoconservative figures were participants in the study, including Bill Kristol and Paul Wolfowitz, the proposals and strategy outlined in the document became a part of the neoconservative ideology of George W. Bush.
Many of the proposals outlined in the document, including a strong national defense, American leadership in the world (referred to as "Pax Americana"), space exploration, missile defense, and surveillance, were major features of the Bush Administration's policies.
Conspiracy theorists cite portions of this document in their arguments, most notably the following quote on Page 51:
"Further, the process of [strengthening the military], even if it brings revolutionary change, is likely to be a long one, absent some catastrophic and catalyzing event – like a new Pearl Harbor."
9/11 conspiracy theories and anti-Semitism
Conspiracy theories regarding the 9/11 attacks are often used within an anti-Semitic context. Some people have always complained about the influence, to varying degrees, of AIPAC and similar pro-Israel lobbying groups within the US government and American foreign policy. Many of these people consider that 9/11 was allowed to happen in order to benefit Israel, and/or the Jewish people, by means of the subsequent wars in Afghanistan and Iraq. Some have even gone as far as to say that the Israeli government commissioned the attacks rather than al-Qaeda.
“It appears that much of the American public, perhaps 35 percent, perhaps more, rejects the official story, with a significant percentage of these influenced by the 9/11 Truth Movement. On the question of what is “reliable,” I have been part of a group called “9/11 Consensus,” which is publishing articles against the official story that have been OK’d by a panel of experts from various fields. Insofar as this becomes known, it should increase the credibility of the 9/11 truth movement considerably. And now that A&E’s video “Explosive Evidence” is on PBS and reportedly attracting big audiences, the numbers should go way up.  Dr. David Ray Griffin is one of the people who is actively involved in the 9/11 Truth Movement. He is a retired American professor of philosophy of religion and theology.
