This is more relevant today than it was when it was originally released in 1983.
Former CIA agent Frank Schnepp perfectly describes the process of laundering disinformation to the press in order to get the public to believe government narratives:
Based on this testimony, the CIA would lie to journalists, float the same lie within their own agency and agencies in other countries so that journalists would corroborate it, and peddle false information through trusted media figures.
And if you think he's lying, consider that the U.S. government sued Schnepp all the way to the Supreme Court.
