"How many hi-jacking incidents have there been in the United States of America? (World-wide there have been 897 between the years 1967 to 1996)"
Hardly the point. The point is, how could four commercial airliners be simultaneously hijacked, and the US military not respond? At all?
There are profound, serious problems being covered up regarding national security and 9/11 by the Bush administration. The refusal of the Bush administration to cooperate with the investigations, their obsession with secrecy, and their arrogance towards anyone with a genuine, legitimate interest in investigating the facts surrounding events and circumstances leading up the biggest national security lapse since Pearl Harbor, is nothing less than evil. And the word 'evil' is not one I bandy about or use lightly. I personally reserve use of the word to circumstances that fit the dictionary definition of it.
There is a pattern of secrecy, spinning, lying, deception, and cover-up in this administration that hasn't been seen since I don't even know when. One never really had the sense that Nixon's lawbreaking and exploitation of his power at the expense of his so-called "enemies", could result in what we are seeing now. Which is a gutting of civil liberties in the US, so that this administration can complete their imperial march to conquer the oil and gas regions of the planet by January 2009.
