Zeitgeist.
I've heard the stuff about the federal banking system before. Obviously heard the stuff about 9/11 too. The rest was something of a revelation, although a bit outlandish and seemingly speculative the part that drives towards world domination etc. The religion bit was instructive, but it wasn't ultimately used to make any kind of point, which I thought was odd.
It's fascinating in the way that history always is. We will never know the truth, that's for damn sure. Even if there is anyone who knows the truth they will never divulge it. Meanwhile the truth about historical events might either be kept very securely out of sight or lost already.
So all you can really do is throw your arms up in the air and day "who knows".
