Just going to link to a few stories you should read, like this:
In 1999, there were a handful of Arab flight students in SW Florida. In 2001 there were thousands. At a big AFB base in the Panhandle, a trainer told me, “It used to be Iranians. Now its all Saudis.”
Were they there by themselves? Hell no. Did the CIA know? Hell yes. I asked an old hand, in a highly irate tone of voice, how could the CIA not have known blah-di-blah blah. His answer was mild. Why, I’m sure that they did know. He said, “It would have been impossible for them not to.”
Venice and the surrounding region was teeming with spooks. The Sheriff in nearby Charlotte County—where Atta lived for a time, though you won’t find that in the 9/11 Commission Report—told me that, because of the 40-year history of covert activity that he had seen been run through Charlotte County, which he and everyone else in the Charlotte County Sheriff’s Department had been powerless to stop, he believed the CIA was responsible for 9/11.
Was one of the bigger shocks of my life. A Southern cracker Sheriff telling me he thought the CIA was responsible for 9/11. And hey. Maybe he’s right. But I couldn’t go there. I might believe that. But I never had proof.
Here are some other snippets from www.historycommons.org...
“9/11 Commissioner John Lehman repeatedly meets with Bush administration officials and discusses links between the 9/11 hijackers and Saudi government officials.”
“Lehman is aware that the Commission’s investigators are working the topic and is interested to see what they will find. According to author Philip Shenon, “He thought it was clear early on that there was some sort of Saudi support network in San Diego that had made it possible for the hijackers to hide in plain sight in Southern California.” He is especially intrigued by money possibly passed from Princess Haifa, wife of the Saudi ambassador to the US, to associates of the hijackers, although Lehman thinks she would not have known the money’s real destination and had simply signed checks given her by radicals at the Saudi embassy in Washington. Lehman also doubts that the Saudi officials knew the details of the 9/11 plot, but thinks they knew the hijackers were “bad guys,” and “The bad guys knew who to go to to get help.”
“However, there is an absolute lack of interest on the administration’s part about the Saudi information. According to Shenon, “Lehman was struck by the determination of the Bush White House to try to hide any evidence of the relationship between the Saudis and al-Qaeda.” Lehman will say: “They were refusing to declassify anything having to do with Saudi Arabia. Anything having to do with the Saudis, for some reason, it had this very special sensitivity.”
And this:

Saudi Arabia and Israel are not our friends and they never have been.
Each of them will do what is in their best interest, not what is in our best interest.
We want Saudi oil and we will sit still for all manner of Saudi outrage to get it.
Our politicians live in fear and trembling of the terms “blood liable” and “anti-Semitism” being thrown at them from the Israelis.
The Saudi royal family only survives because the Wahhabists allow them to.
Wahhabism is the most virulent and violent strain of Islam, and is responsible for Bin Laden, al Qaeda, ISIS and all other radical Islamic extremism.
That’s who the world should be at war with.
Israel survives in its current manifestation only because corrupt American politicians allow it.
