Also, multiple bush regimes set up the circumstances that led to 9/11 starting with funding and arming the mujahideen. Bin Laden didn't come out of nowhere and the invasion of Afghanistan was completely unnecessary in terms of catching him and others who orchestrated the attack. Even Al-Qaeda offered to hand him over before the invasion and they weren't the last group to offer handing him over.

Bush Sr, Bush Jr, and many other ghouls indirectly setup 9/11 and then made the fallout larger than it needed to be to achieve their stated goals. The blood of millions is on their hands and 9/11 was a drop in the bucket. They deserve to be tried, convicted, and locked away as war criminals, not to sit out retirement painting and pretending they did no wrong.
