The US did supply the Mujahideen in Afghanistan in the 1980s and Al Qaeda did eventually arise from the Mujahideen so 9/11 is certainly blowback but the CIA would need to be funding and aiding Al-Qaeda operatives during the late 90s to 2001 for there to be equivalency with Saudi but I’m not aware of any evidence to support that. Besides, the point wasn’t that the CIA was innocent it was that Saudi was guilty.
