I almost hesitate to even post this, but I'm going to.
This is the right place to post this, unlike some other posters seem unable to understand.
Here's what I think happened. And this is by no means meant to take away from the loss of life that day. In fact, it may even make it more of a national tragedy if my theory is right.
So here goes:
9/11 was not a planned inside job by the US government.
However, I do believe that the powers that be at the time (read Dick Cheney; you can laugh at me if you want, but we see where he took us) knew that something was abrew. I think they allowed whatever it was to happen, perhaps figuring a bombing or two of a mall or stadium or significant government building of that sort would suffice to get Dick Cheney into the Middle East (he practically admitted as much in a private Halliburton meeting in 1999, most likely not meant for consumption.) So I don't think they really tried that hard to stop it.
I don't think for one second they ever thought it would be this big.
They were very wrong.
They ****ed up big time.
Tried to correct it with a glorious short war in Iraq.
****ed up again.
And here we are.
You can laugh at this if you want, but I firmly believe it.
I think they originally thought the intelligence gap might lead to a couple dozen Americans blown up in a mall, which would have been sufficient for their aims.
Regardless, here we are.
You can poke fun of the Obama administration all you want, but there has never been a more disastrous (and possibly even traitorous) administration than that held by President Dick Cheney.
