I looked through them and they weren't specifically related to 911. I think the best match is with the dropping of the atomic bomb. (The "twin gems" are Hiroshima and Nagasaki.) But really they're so vague that they could relate to any military action in the 20th Century.
Since the key phrase is "Bush hid the facts", we can rule out 911 and the A-bomb, since there's no evidence that Bush hid any facts relating either to those.
My first guess was that it was a reference to the bombing of Baghdad at the start of the second Iraq War. Certainly somebody hid the facts about Saddam's WMD capabilities, but I'd be surprised if it was Bush, because I don't think he's that smart. (I'm pretty sure it was a Cheney project.)
Then I realized...maybe it was a reference to Bush Sr. There are solid rumors that he was involved in the Iran-Contra coverup, and that fits all your symbols pretty well. (Remember that Iran-Contra was entangled with the Iran-Iraq war and with the civil war in Nicaragua.)
Of course, it could also be a reference to an event that hasn't happened yet.
Is there any chance you can figure out a way to get times and dates from your files? If we could get some specific predictions with dates then that would qualify for the Challenge.
Yes, The letters of the alphabet weren't very specific, but the answers to my specific questions were more revealing to me:
‘Are we communicating paranormally?’
N - interrogative or exclamatory final particle, hill; elder; empty; a name, plesiochronous.
Dictionary.com:
<communications>
Nearly synchronized, a term describing a communication system where transmitted signals have the same nominal digital rate but are synchronized on different clocks.
According to ITU-T standards, corresponding signals are plesiochronous if their significant instants occur at nominally the same rate, with any variation in rate being constrained within specified limits.
