I believe the US government planned and carried out 911 in order to start a huge war, scare the people into unity and submission under their rule, and to have a carte blanche to do whatever the hell they wanted and focus all of the people's money on the military and away from domestic social issues, also to control territory and oil and achieve power, and to allow the right wingers to win a second term after they plotted and executed the perfect stolen election (i.e. somehow rigged) in 2000.

Ditto. Or at least had complete knowledge of it, let it happen and assisted certain buildings to aid the anger of the US citizen to promote a war plan that has spread from a 3rd world toilet, that couldn't have defended itself against us to another toilet that was still crippled from the Gulf war. Now's it's backfired in his face. But there's been too many questions and in this day and age of video cameras, too many people watching and questioning. If it came out, it would lead to civil war, or at least one Hell of an uprising.
And the fact that UFO's have crashed on Earth, some landed and have had an exchange of intelligence that the Governement is slowly releasing over the years through patents. Carbon Fiber... LEDS, etc...
The only reason they don't tell us, is it would lead to a complete breakdown of the religious system, because they believe they are the center of the universe. If it came out there would be two camps, the Believers and non-believers. Forget normal everyday things...
