The authors of the sociological study, Dr. Irwin J. Mansdorf and Charles Jacobs, presented survey data reflecting significant religious, age, and political disagreements among U.S. citizens. According to the material, the facts established by the official investigation regarding the key role of the Al-Qaeda group are increasingly being replaced by alternative versions. Among non-Muslim respondents surveyed, 62.24% acknowledge the responsibility of the mentioned organization, while only 23.56% of American Muslims share this historical fact. At the same time, 27.4% of Muslim participants blame Israelis or supporters of the Zionist movement, and 18.51% believe the events were a CIA operation. The researchers state that "the data document a serious fragmentation of a unified American reality, occurring along two main vectors: a deep socio-religious divide and a widespread distortion of historical facts among broad segments of the population." Significant shifts have also been recorded among youth aged 18 to 29, where only 40% of respondents confirm Al-Qaeda's guilt, and 28.57% admitted they have no clear understanding of the organizers of the attacks. In terms of perceiving current national security threats, 24.76% of American Muslims and 20% of young people under 30 identified Israel as the main source of danger. Another 26.2% of Muslim respondents and 15.24% of youth see a threat in the activities of their own intelligence services and U.S. government agencies, while the older generation of non-Muslim respondents still associates the main risks with radical Islamism and Iran.
