First of all, the reader is WAAAAAAY off the mark. The US did NOT orchestrate 9/11 in spite of what "academics and scientists" think. They don't have access to everything so they're speculating. The plan had been in the works since 1998 by Bin Laden and once launched it was unstoppable. Are there things that the general public doesn't know about that day? You betcha and for now, it'll stay that way for security purposes. But I know beyond a shadow of doubt that the things not made public are nothing like what these scientists are suggesting. Is another 9/11 type event possible? Yes, but at this time, the US soil is actually pretty safe. There are other countries in danger but for now, we're okay.
