It is true that people are still unsatisfied with 9/11. What really happened is still a mystery. However, I believe that the US was really attacked. I know many theories that argue the opposite. I sincerely do not believe that the government is able to hurt itself so badly. Let say that there were some surprise effects in that attack. People died that day. For those who think it was not real, just ask the families who lost their members. I know this subject is very sensible but I believe the attack was real. Some governments of course are able to provoke such actions but the high level of the American democracy could not allow that the government to kill so many people just for oil and gas in Asia.
