All of what you said is indeed very true and can be proven. Also, what about the Pakistani ISI who helped mastermind the planned 'hijack'? It is a well known fact that the Pakistano ISI owes it's existence to the CIA for christ sake!
Here's a good question: What would happen to the reliablitity and trust of the Government, particulary the Bush Administration, if in the light of all of the evidence emerging, the truth came out that there was a huge cover-up?
The truth is, the biggest terrorists in any case are our own Government. The fact is, America and Britain currently have stockpiles of nuclear weaponry, you might think that that would be considered to be 'harbouring weapons of mass destruction'. And it is these nuclear arms that eventually get sold to alot of 'enemy' countries. It's absurd.
