I'm not by nature a conspiracy theorist. I don't think the grassy knoll is here. But, I do think that the US government propagandizes inside, and outside all the time and has done so continuously, since the birth of the modern communication era.
You write as if the Vietnam war just didn't happen. That routine abuses by US armed forces in the middle east just didn't happen. As if Snowden just didn't happen.
Maybe I missed the /s in this. Btw, if I got a whack from the site I wouldn't deny this may not be a useful discussion, but I really do mean it: I think this cannot be read, except as a counterfactual non-reality.
