BBC's The Power of Nightmares

Watched an interesting 3 part series this weekend. It is available via bittorrent. I highly recommend watching it (I understand that it was shown on the CBC last year.)
Each episode starts with the following:
In the past, politicians promised to create a better world. They had different ways of achieving this, but their power and authority came from the optimistic visions they offered their people. Those dreams failed and today people have lost faith in ideologies. Increasingly, politicians are seen simply as managers of public life, but now they have discovered a new role that restores their power and authority. Instead of delivering dreams, politicians now promise to protect us: from nightmares.
They say that they will rescue us from dreadful dangers that we cannot see and do not understand. And the greatest danger of all is international terrorism, a powerful and sinister network with sleeper cells in countries across the world, a threat that needs to be fought by a War on Terror. But much of this threat is a fantasy, which has been exaggerated and distorted by politicians. It’s a dark illusion that has spread unquestioned through governments around the world, the security services and the international media. This is a series of films about how and why that fantasy was created, and who it benefits.
At the heart of the story are two groups: the American neoconservatives and the radical Islamists. Both were idealists who were born out of the failure of the liberal dream to build a better world, and both had a very similar explanation of what caused that failure. These two groups have changed the world, but not in the way that either intended. Together, they created today’s nightmare vision of a secret organised evil that threatens the world, a fantasy that politicians then found restored their power and authority in a disillusioned age. And those with the darkest fears became the most powerful.

I’m going to comment on this once my brain stops hurting.

I thought this actually had to do with Nightmares, since I happen to like them.

An engineer, a physicist, and a mathematician are shown a pasture with a herd of sheep, and told to put them inside the smallest possible amount of fence. The engineer is first. He herds the sheep into a circle and then puts the fence around them, declaring, “A circle will use the least fence for a given area, so this is the best solution.” The physicist is next. He creates a circular fence of infinite radius around the sheep, and then draws the fence tight around the herd, declaring, “This will give the smallest circular fence around the herd.” The mathematician is last. After giving the problem a little thought, he puts a small fence around himself and then declares, “I define myself to be on the outside!”

Three engineers are sitting around one day discussing what kind of engineer God must have been.

“I say God’s a mechanical engineer,” said the first one. “Look at the fantastic skeleton and musculature of the human body!”

“You’re wrong,” said the second one. “I say he’s an electronics engineer. Look at that fabulous brain and nervous system.”

“No, no, no! You’re both wrong!” said the third. “He’s definitely a civil engineer. Who else would run a waste disposal line through a recreational area?”
