Why is there so much controversy surrounding 9/11?

9/11 is a controversial event because of the numerous unanswered questions and inconsistencies in the official explanation of what happened on that day. The scale of the attacks, the subsequent wars in Afghanistan and Iraq, and the major changes in US foreign and domestic policies that followed have all contributed to the ongoing debate and speculation about the true nature of the events of September 11, 2001. Some people believe that the official explanation of the events is incomplete or inaccurate, and that there may have been additional factors or individuals involved in the planning and execution of the attacks. This has led to the rise of various conspiracy theories, which continue to be widely discussed and debated, even two decades after the events of 9/11.
