You're making extraordinary claims regarding the parallels with the Reichtag fire. I won't ask for extraordinary evidence, just reasonable evidence.
The part I don't get is why it seems to matter so much whether 9/11 was an unexpected attack or a planned conspiracy, or whether it was anticipated but not orchestrated by the government. The effect is all that matters, and the effect was, in fact, exactly the same as the Reichstag fire... which is itself not universally agreed to have been sanctioned by the Nazis.
But the acts perpetrated by the US in retaliation for 9/11 were far worse than the act itself. That would still be true regardless of whether or not the tinfoil-hat brigade is right.
