In the latest episode of Doctor Who, the Doctor was faced with a breakdown in the ceasefire between humans and the extremist faction of an alien race that has been living secretly on Earth. He then came out with a speech that sums up all wars.
He then followed it up with this.
He had engineered a war game so that both humans and the aliens believed that they had a 50% chance of winning or losing, entirely at random. This led to the accusation of playing games.
The episode aired last Saturday and a lot of people are still raving about it.
And how applicable this argument is to all wars.
If you're in the UK, you can watch this moment on BBC iPlayer from roughly 31:30 minutes in.
