A genuine soldier wouldn't have posted on the internet, but would have tried to blend in without being noticed, and wouldn't have made himself public. After all what is the purpose in that, unless he was going to tell us to do something to change the course of the future, but he didnt as it can't be.
Sounds like a bit of a conspirasist (possible new word).
Edit: Just reading that article, it is fairly interesting, althought very mysterious. I guess we'll have to wait and see if there is an American civil war, although I'd be suprised as they all seem pretty united with the "God bless America" stuff. Don't think there was any conflict with all the bombing Iraq between the public and government.
Who knows
