If I simplify a bit, there are just two main cases to consider: Either
(1) 9/11/2001 was an inside job, a false flag, by the Deep State, or
(2) 9/11/2001 was retaliation for past crimes by the Deep State.
I’ve heard strong and passionate arguments on both sides; we’re far from reaching a national consensus on which of those two cases is true. But in either case, the Deep State is to blame. So in either case, what we need to do is to reduce the Deep State or end it entirely. (And to do that, we may need to change our economic system; and to do that, we may need to spread a lot of understanding first.) And it would be best if we go ahead with ending the Deep State without waiting for a consensus on the 1 versus 2 question.
For that reason, I believe that much of the argument over 1 versus 2 is unproductive, and not the best use of our time.
