is it true that the US intelligence services organized September 11, 2001. give me an explanation
Well, there are simply no proof that US intelligence services organized the collapse of the World Trade Center buildings on 9/11, 2001.

All current evidence points to Islamic extremists affiliated with Al-Qaeda being responsible, and evidence suggesting otherwise are circumstantial at best and baseless at worst.
Could you give me a detailed breakdown of the reasoning the people who think it was a planned attack by the government give and why it is nonsense?
