Iranian President Ahmadinejad's comments at the UN raised the issue of US government involvement in the attacks. An Al Jazeera article covering these remarks included a section with the title 'Alternative Perspectives." The segment included the following:
The most popular website on so-called alternative views on the September 11, 2001, attacks seems to be 911truth.org. The site acts as a clearing house for an array of various views and refuses to articulate an exact position on who it believes launched the attacks and why. Rather, it poses a series of questions, while offering readers the "Top 40 Reasons to Doubt the Official Story".
A "documentary" called Loose Change questioning the official 9/11 narrative, has been popular among activist groups and other more traditional doubters.
"That 19 hijackers are going to completely bypass security and crash four commercial airliners in a span of two hours, with no interruption from the military forces, in the most guarded airspace in the United States and the world? That to me is a conspiracy theory," Korey Rowe, the film's director, told Time magazine.
Mainstream media in the West, and even the US government itself, have felt a need to respond to these theories. The US state department's Bureau of International Information Programs has a website devoted to debunking the "top September 11 conspiracy theories".
In a piece titled "Why the 9/11 Conspiracy Theories Won't Go Away", Time argues that what many would call conspiracy theories are "not a fringe phenomenon".
