What better way to promote infighting and disagreement among the conspiracy research community when trying to analyze the event?
Throw some bombs in the bases (see Barry Jennings) and some squibs throughout the buildings, and you have the "controlled demo" proponents.
Toss in some industrial grade thermite, hire the painfully blatant spook Dr. Steven Jones to push the thermite red herring, and you have the thermite OP proponents.
I'm not sure about the mini-nukes...perhaps one was used?
The biggest of them all, and the reason the other "methods" were used as distraction, is the clear evidence of Directed Energy technology used to dustify the towers.
Judy Wood's "Where Did the Towers Go?" is the final word on their destruction. The shills are tasked to "debunk" her but they can only go "hurr durr space laser!" when she literally never mentions space and doesn't try to identify the weapon itself.
Watch the "collapse" of the towers again. This was the debut of high technology for those who were paying attention. It was a "hey, look what WE can do" moment for humanity, and a moment of great evil and deception for all of human history.
So they used bombs, they used thermite, and they "dustified" the towers just to be sure.
Now the conspiracy theorists are arguing about HOW it was done instead of joining forces, stepping back, and looking at the bigger picture and the historical and technological context of the event.
9/11 woke up a lot of us. We must continue to use the event as a catalyst for red-pilling the planet.
It may be our last chance.
