"Propaganda only works if people don't know it's happening — if they don't think of its source as untrustworthy."
An old joke: a Russian and an American are on a airline flight from Moscow to Washington. The American asks the Russian what he does for a living.
The Russian answers "I work for the government."
"Why are you traveling to the United States, then?"
"I want to study American propaganda techniques."
The American responds, a smug look on his face "oh, but there is no propaganda in America!"
"Exactly!" the Russian replies.
People in the Soviet Union also thought that they were the freest in the world.
