I did not question the official story for a few days after the event, but by a few weeks into it, as I recall, I had already crossed the 50% probability threashold toward thinking it was likely an 'inside job'. At this point I am up into the 'near certainty' range given the mountains of evidence uncovered over the decade.
9/11, and the wars that it facilitated were, to me personally, a giant gift. I started seeking alternatives to USD for mainly ethical reasons and stumbled into PM's.
Over the years I have come to the belief that 9/11 can indeed be considered a 'necessity' for the 'wellbeing' of our nation. I suspect that without control of Iraq and the central Asian areas we have, the US monetary system very likely would have collapsed by now and the US people could not enjoy a quarter of the worlds resources. One of my remaining beefs has to do with the distribution of the spoils amongst our population...not a lot of it, by percentage, goes to the bullet stopper class who does the heavy lifting (as was more the case after WW-II.) We still have obesity problems amongst the lowest class however so it is not fair to say that we all do not benefit...for now at least.
The 'sacrifices' in blood on 9/11 were surprisingly minimal. The pesky Enron investigation vanished in building 7, and Sliverstein did not have to worry about his asbestos problem and got quite an insurance settlement instead. Nicely done! Not sure what happened to the gold in the vaults under the place, but I'm sure it found a good home. There were a great many winners from 9/11 and not to many losers. The losers in follow-up wars can feel good about sacrificing with the name of God and Country.
But 9/11, Afghanistan, Iraq, Libya (and likely soon, Iran) are just band-aids to buy some time. Certainly not a whole 'New American Century's worth I don't believe, and I feel that Eastasia has a stronger hand when they decide to play it. I'll expect more 9/11's and Osama's and so on and be positioning myself to graze in whatever pasture end up being the most green.
