> Additionally, the fact that members of the Saudi government aided and assisted the hijackers...
Details? My understanding is a huge fraction of the Saudi population have jobs that amount to government sinecures (while immigrants do most of the real work). Are we talking about high-level members with real leadership positions, or some minor member of the royal family working in some ministry doing nothing and going off on his own?
Saudi politics and personal relationships are a mess. It is true that Bin Laden is a member of a very powerful family in Saudi and so obviously has a lot of personal connections there as do his close associates. He is however estranged from that family and has been for a very long time, but may have some in Saudi who have grievances against the house of Saud and are sympathetic to the jihadis.
Al Qaeda and many other jihadi outfits procure a lot of their funding from Islamic charities and schools (Madrassas) with complex and very opaque financial dealings. Also the Saudi government and individual Saudis donate to many Islamic charities, so its highly likely some of that money ends up with the jihadi's including Al Qaeda.
So yes there's almost certainly some truth to the allegations. Some powerful Saudis may secretly support them, some donate to charities and the money ends up with them, but no this is not official Saudi state sponsorship of Al Qaeda. In fact Al Qaeda consider the Saudi royal family and all of their associates to be apostates (essentially heretics) who can be killed summarily and they advocate for regime change and the establishment of a Caliphate.
Like I said, it's a real mess of family loyalties, rivalries, swinging political fortunes and opaque dealings. Game of Thrones has nothing on these people. Just look at what happened to Jamal Khashoggi.
A court affidavit filed on 3 February 2015 claims that Zacarias Moussaoui was a courier between Osama bin Laden and Turki bin Faisal Al Saud in the late 1990s, and that Turki introduced Moussaoui to Bandar.[76] Zacarias Moussaoui stated on oath and wrote to Judge George B. Daniels that Saudi royal family members, including Prince Bandar, donated to Al-Qaeda and helped finance the 11 September attacks.[77] The Saudi government continues to deny any involvement in the 9/11 plot, and claims there is no evidence to support Moussaoui's allegations in spite of numerous previous intense investigations, noting that Moussaoui's own lawyers presented evidence of his mental incompetence during his trial.[76] Leaked information from the redacted portion of the 9/11 Commission Report states that two of the 9/11 hijackers received $US130,000 in payment from Bandar's bank account.[78]
