So what are you suggesting? The Bush administration engineered a plan to allow terrorist's to fly planes into the towers so "some" corporations could profit from a war in Afghanistan and Iraq? Were we to round up all these suspects before hand and do what with them before they do what? Did we know they were targeting the towers and pentagon among other things?
Overall, experts agree, no way it was preplanned by Bush. To many people involved for a cover up in that respect.
It's like when we know someone is crazy, but after he kills people the finger pointers come out and say we should have stopped him before he did it, and the ones who knew he was unstable are at fault.
I don't think conspiracy theories are worth spit here.
One is taught in Intelligence training to exclude coincidence from your thought pattern. So when Pakistani ISI is caught red handed in wire transfers, put option stock trading is out of control prior to 9/11, and the fact that the CIA trained Bin Laden to fight the Soviets........I'd say the environment is ripe for speculation.....
