Look, I'll say it again, if you want to believe some element of the US government knew the 9/11 attacks were going to happen and did nothing to stop them deliberately to start a war, fine. If you want to believe some element of the US government staged 9/11 using CIA operatives, fine. Those are both very possible and I wouldn't be surprised if either turned out to be true.
If you believe that no planes hit the buildings, that it was space lasers, or microwave weapons, that holograms of planes covered up missiles and the planes were flown to a secret location and all the passengers were shot to cover it up, or a make believe substance called "nano thermite" was used in a controlled demolition using the phrase "pull them" which is not a demolition term, and somehow hundreds of thousands of tons of the stuff was secreted into the buildings with no one noticing it, or anything else besides planes hitting the buildings as the sole cause, you're a fucking retard. Physics works, planes took down the buildings, fuck you.
