In his book, 'Propaganda', published in 1928, Edward Bernays wrote: "The conscious and intelligent manipulation of the organised habits and opinions of the masses is an important element in democratic society. Those who manipulate this unseen mechanism of society constitute an invisible government which is the true ruling power of our country."
The American nephew of Sigmund Freud, Bernays invented the term "public relations" as a euphemism for state propaganda. He warned that an enduring threat to the invisible government was the truth-teller and an enlightened public.
In 1971, whistleblower Daniel Ellsberg leaked US government files known as The Pentagon Papers, revealing that the invasion of Vietnam was based on systematic lying. Four years later, Frank Church conducted sensational hearings in the US Senate: one of the last flickers of American democracy. These laid bare the full extent of the invisible government: the domestic spying and subversion and warmongering by intelligence and "security" agencies and the backing they received from big business and the media, both conservative and liberal.
Speaking about the National Security Agency (NSA), Senator Church said: "I know that the capacity that there is to make tyranny in America, and we must see to it that this agency and all agencies that possess this technology operate within the law... so that we never cross over that abyss. That is the abyss from which there is no return."
On 11 June 2013, following the revelations in the Guardian by NSA contractor Edward Snowden, Daniel Ellsberg wrote that the US had now fallen into "that abyss".
