We irrefutably had advanced knowledge of Pearl Harbor, the Vietnam war was conducted on a lie in the Gulf of Tonkin, and operation Northwoods was conspired to be executed. What reason is there to believe the government may of not been involved in 9/11?
I see the "facts" from both sides, but when I see someone who absolutely finds no reasoning as to why the US government would get involved, I see that person as someone who screams ignorance on a level that is hard to comprehend. There is absolutely nothing hard to comprehend about the US government potentially being involved in a terrorist attack, as they have proven to have conspired terrorism on this country before in the past.
