When I say I believe it to a high degree of confidence less than 100%, that's coming from a skeptical viewpoint. You should be aware before you regard it as a wide opening or a fence-sitting position that I also believe in the theory of gravity to a high degree of confidence less than 100%. (In practical terms, my faith in gravity may as well be 100%, but technically it's slightly less.) That's not to say that my confidence in the 19 hijackers theory approaches my confidence in the theory of gravity, but it's very high nonetheless.
And to be clear, I don't argue the government's side. I argue the evidence's side.
My understanding of what happened on 9/11 is constantly shifting, but it never comes close to the Inside Job theory. I've read much more on the subjects you listed than I'd have cared to if 9/11 weren't such a personal topic. I don't see the dots connecting the way many of these authors do. I don't think many of these authors appreciate just how complex and unpredictable the world is. They imagine a fantastic level of control over the most micromanaged details of virtually every major world event or long-term trend.
There is no pre-determined Plan. Only a complex and often chaotic interaction of competing agendas.
