Crossing the Rubicon: 
Simplifying the case against Dick Cheney

Means: Dick Cheney and the Secret Service

Dick Cheney was running a completely separate chain of Command & Control via the Secret Service, assuring the paralysis of Air Force response on 9/11. The Secret Service has the technology to see the same radar screens the FAA sees in real time. They also have the legal authority and technological capability to take 
supreme command in cases of national emergency. 
Dick Cheney was the acting Commander in Chief on 9/11.
Motive: Peak Oil
At some point between 2000 and 2007, world oil production reaches its peak; from that point on, every barrel of oil is going to be harder to find, more expensive to recover, and more valuable to those who recover and control it. Dick Cheney was well aware of the coming Peak Oil crisis at least as early as 1999, and 9/11 provided the pretext for the series of energy wars that Cheney stated, “will not end in our lifetime.â€
Opportunity: 9/11 War Games
The Air Force was running multiple war games on the morning of 9/11 simulating hijackings over the continental United States that included (at least) one “live-fly†exercise as well as simulations that placed “false blips†on FAA radar screens. These war games eerily mirrored the real events of 9/11 to the point of the Air Force running drills involving hijacked aircraft as the 9/11 plot actually unfolded. The war games & terror drills played a critical role in ensuring no Air Force fighter jocks — who had trained their entire lives for this moment — would be able to prevent the attacks from succeeding. These exercises were under Dick Cheney's management.
