I think it's possible the Bush administration infiltrated al Qaida and implanted the idea of 9-11 but that's still a long shot. It would have taken longer than that to get it planned and Bush just hadn't been in power that long. but if it started before Bush took power, it would mean that his presidency was already decided in advance and that he would carry out their little plan--whoever "they" are. That's plausible because Bush lost the popular vote in 2000 but got in anyway. That's cause for suspicion but requires a vast conspiracy at the highest levels of govt that seems unlikely but pretty damned frightening if true. As far as explosives planted in the WTC, that's so absurd anyone who believes it seriously needs psychological counseling.
