In his appearance on Al-Risala TV, Dr. Sultan praised Yemenite sheikh Dr. Al-Zindani, who has been categorized by the U.S. government as a "Specially Designated Global Terrorist" because of his loyalty to Osama bin Laden and his support of Al-Qaeda.  According to the U.S. Department of the Treasury, Al-Zindani "has a long history of working with bin Laden, notably serving as one of his spiritual leaders. In this leadership capacity, he has been able to influence and support many terrorist causes, including actively recruiting for Al-Qaeda training camps." 
The following are excerpts from Sultan's May 17, 2006 address on Al-Risala TV. TO VIEW THIS CLIP, VISIT: http://memritv.org/clip/en/1143.htm .
Salah Sultan: "The film 'The Siege,' starring Denzel Washington, portrayed the Muslims in a very bad light. They are shown calling for prayer, performing the ablution, praying, and then planning multiple bombings - a government building, a security agency, the FBI, a bus carrying young men and women, adults and children. They bombed shops.
"The film came out in April 1999. It paved the way for 9/11, since it was filmed in Brooklyn, New York. The truth is that immediately after 9/11, I said people should view these events in the context of 'The Siege,' because these events were identical.

"This scenario... I still believe to this day... This scenario still baffles me. I share the view of many Americans, French, and Europeans, who say that 9/11 could not have been carried out entirely from outside [the U.S.] - by Muslims or others. The confessions by some people could have been edited. But even if they were not edited, I believe that these people were used in a marginal role. The entire thing was of a large scale and was planned within the U.S., in order to enable the U.S. to control and terrorize the entire world, and to get American society to agree to the war declared on terrorism - the definition of which has not yet been determined.
"The U.S. remains the only country to determine who is a terrorist, and what is the definition for terrorism, and it can pin it on anyone. The most recent instance is the case of Dr. Al-Zindani, who has been accused of terrorism, even though he is known worldwide for his refinement, virtue, and broad horizons."
