There are many conspiracy theories in circulation on who was plotting the 9.11 disaster. Some people think that CIA knew all about the attack, but intentionally let the terrorists pull it through. It was not incompetence and negligence that made the attac possible. This was because they wanted to create an excuse to invade Iraq and to launch the war on terror to strengthen the American global dominance and the plan for a new world order.
Others think that Mossad in Israel planed it because they wanted a war to get rid of Saddam; or maybe the Skulls and bones or the Freemasons or PNAC or the Devil himself had a finger in the pie.
The conspiracy theories flourish because the official story doesn't hold water. Of course we create theories when we don’t know what's going on. This is one of the most important functions of the mind. We mass produce theories and then we form groups in favor of the different beliefs. And then we fight each other.
This is why we have so many different religions. We don’t know what is going on. We don’t know what life is about, really. We don’t know where we are coming from, who we are and where we are going. There is so little we know for sure. The scientists produce stark proofs and evidences that ten years later are proved to be wrong. We are all blind trying to lead the blind.
