We will never know the whole truth...because even they don't know the whole truth...all we will ever know for sure is that three planes got hijacked, two went into the towers and one was taken by the passengers and forced to crash before reaching it's ' probable ' destination...
we don't even know who was really responsible...you could theorize it was perpetrated by anyone really...wouldn't be the first time people were sacrificed for the cause of going to war...unlikely, but still probable...
pearl harbor was claimed to been allowed to happened on purpose to draw America into the war...the theory is Churchill knew a week before it happened and chose not to warn the US...Bush senior was long suggested as the person behind the assasination of JFK when he worked for the CIA...
when i was a kid the schools taught an ice age destroyed the dinosaurs, now it's a meteor...Christopher Columbus discovered America, now he didn't...
the only thing we know for sure is that we are alive...
