You are a little condescending in your remark that anyone outside the US can see it. Well, a lot of Americans can see it.
But I'd assert that the idea of propaganda being inherently negative is a rather American notion. It originally meant "that which should be spread." The Russians thought propaganda a good thing, like evangelism. And we now accept that ALL communication is subjective by its very nature. In fact, the concept of propaganda as inherently evil and avoidable is a real bit of American propganda in action! It's bad when the bad guys do it. because they are lying. When the good guys do it, it's not propaganda. It's a public service. :) hahaha
Anyway, I guess you meant "subliminal propaganda supporting the war and the Administration and unchecked capitalism."
Yes. This is why I believe media criticism should be taught the moment a child starts school. Even then you are already unteaching them 5 years of ingrained behavior. "Pretending that you already know the answer when you don't is not actually very helpful." ~Migeru.
The point is that sophisticated, evil propaganda works continually, even to the point of sapping the strength of those who wish to fight it. "Life shrinks or expands in proportion to one's courage." - Anaïs Nin
