The film is called Bitter Lake. It is a bit of an epic - it’s two hours twenty minutes long.
It tells a big historical narrative that interweaves America, Britain, Russia and Saudi Arabia. It shows how politicians in the west lost confidence - and began to simplify the stories they told. It explains why this happened - because they increasingly gave their power away to other forces, above all global finance.
But there is one other country at the centre of the film.
Afghanistan.
This is because Afghanistan is the place that has repeatedly confronted politicians, as their power declines, with the terrible truth - that they cannot understand what is going on any longer. Let alone control it.
The film shows in detail how all the foreigners who went to Afghanistan created an almost totally fictional version of the country in their minds.
They couldn’t see the complex reality that was in front of them - because the stories they had been told about the world had become so simplified that they lacked the perceptual apparatus to see reality any longer.
And this blindness led to a terrible disaster - support for a blatantly undemocratic government, wholesale financial corruption and thousands of needless deaths.
