The fact of the matter is that Nano-thermite was found in the 9/11 wreckage. So what is Nano-thermite? It's the most powerful militarily grade demolition material known to man. So who put Nano-thermite in the beams of the twin towers and the Solomon Building? Nobody knows for sure. Did some of our government officials have advanced knowledge that the 9/11 attack were coming? Probably! Did they stand down? The evidence points in that direction.
