These are among the best summaries that I've come across that point toward the larger narrative, although there are many others.
9/11 research is a rabbit-hole of Byzantine complexity full of snares and delusions and peopled with false friends, lunatics, earnest lost souls and a few heroes. It's not necessary to understand all the nuances of science and bureaucracy that allowed the government to get away with mass murder, blame it on swarthy foreigners (of whom many are eager accomplices) and use the incident as (in the words of the Cheney, Jeb Bush et al cabal, the Project for a New American Century) "a new Pearl Harbor." At this critical juncture in human history, it's only necessary to understand why they did it. The motive was Peak Oil, a disaster which will affect everyone on the planet, about which all must enlighten themselves and for which all must prepare.

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."
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.

Many of the "big names" in 9/11 "truth" don't talk about Peak Oil and most of the "big names" in Peak Oil awareness ignore 9/11 complicity.
One of the best early voices for the 9/11 - Peak Oil connection has apparently stopped connecting the dots between them. Barrie Zwicker, whose film "The Great Deception" (2002) was the first documentary (and a very good one), went on to narrate the film "The End of Suburbia" (2004), perhaps the most popular documentary introducing Peak Oil issues. In 2005, his book "Towers of Deception" spent 400 pages examining the media coverage of 9/11 but avoided the 9/11 Peak Oil connection (and also ignored the media strategy of highlighting the false claims to avoid the best evidence).
