9/11 is a setup...
I'll tell you why..
What would you need to do in order to allow a whole country to condone an attack on another country???
Second to that what industry in this world makes the most money???
What happens when people get to much money and power??
Those towers fell after explosions in the buildings, The supports were all cut at 45' angles just like a profession demolition job...
Also the pentagon... a plane hit it?? although no signs of an aircraft was found, and second to that every security camera in the area that would have seen this plane comin was confiscated by the FBI immediately after the attack happened.
The hole in the building was not the size of said plane....
Another thing you don't realise is that another building also was destroyed in USA without anyplanes hitting it. This building fell in the same time as the two towers.
you wanna learn more watch this for one...
