Since the perps were Saudis, it’s pretty clear who it was.
And remember, when loyal Americans weren’t allowed to fly on airplanes, Bush gave the Saudis a free pass to fly where they wanted to go.
Not even one of the attack leaders was a Saudi. Just the ‘muscle’... The ones bin Laden bragged weren’t even told what the mission was and were led to believe was just a hijacking.
But the leaders of the attack who flew the planes had in common the city of Hamburg Germany and all these had a connection to Syrian intelligence officer and a Syrian imam. Syria of course is an ally of Iran and was host to a long-term enemy who has since assumed room temperature, Imad Mugniyeh, the terrorist who was responsible for the Marine barracks bombing in Lebanon and who captured the CIA station chief Buckley and hauled him to Iran for interrogation.
The financing went through the bank al Taqwa and Lugano Switzerland.
