Inside the invisible government: war, propaganda, Clinton and Trump

The American journalist, Edward Bernays, is often described as the man who invented modern propaganda.

The nephew of Sigmund Freud, the pioneer of psycho-analysis, it was Bernays who coined the term "public relations" as a euphemism for spin and its deceptions.

In 1929, he persuaded feminists to promote cigarettes for women by smoking in the New York Easter Parade – behaviour then considered outlandish. One feminist, Ruth Booth, declared, "Women! Light another torch of freedom! Fight another sex taboo!"

Bernays' influence extended far beyond advertising. His greatest success was his role in convincing the American public to join the slaughter of the First World War. The secret, he said, was "engineering the consent" of people in order to "control and regiment [them] according to our will without their knowing about it".

He described this as "the true ruling power in our society" and called it an "invisible government".

Today, the invisible government has never been more powerful and less understood. In my career as a journalist and film-maker, I have never known propaganda to insinuate our lives as it does now and to go unchallenged.

An example. Imagine two cities.

Both are under siege by the forces of the government of that country. Both cities are occupied by fanatics, who commit terrible atrocities, such as beheading people.

But there is a vital difference. In one siege, the government soldiers are described as liberators by Western reporters embedded with them, who enthusiastically report their battles and air strikes. There are front page pictures of these heroic soldiers giving a V-sign for victory. There is scant mention of civilian casualties.

In the second city – in another country nearby – almost exactly the same is happening. Government forces are laying siege to a city controlled by the same breed of fanatics.

The difference is that these fanatics are supported, supplied and armed by "us" – by the United States and Britain. They even have a media centre that is funded by Britain and America.

Another difference is that the government soldiers laying siege to this city are the bad guys, condemned for assaulting and bombing the city – which is exactly what the good soldiers do in the first city.
