Self-Destruction

The most destructive act in human history was WWII. And everything that happened after that was related to it.

In Europe, the EU was formed, with its own currency, the Euro. But the UK has decided to leave the EU, for reasons that go back to WWII. It was the head of the British Empire before the war, and it wants that back.

It is determined to turn the clock back. And the US is determined to do the same thing. It came out of the war, the strongest nation in history, and now it wants that greatness back.

But time only runs one way, and this cannot be done. What is happening instead is self-destruction.

How does this work? Why do people turn against themselves? They can see they are not as powerful as they once were, and they blame themselves for this.

You will object that this oversimplifies the situation, and this is a valid objection. I am only saying this theory explains many of the world's problems.
