If you want to gain an insight into how the enemy was thinking, its worth listening to the original video where this clip comes from:

Yuval Harari with Dan Ariely: Future Think—From Sapiens to Homo Deus

Its very surreal listening to how calmly they discuss the craziest things and seem to diligently believe it themselves, but with the clarify of 8 years into future knowing everything they discuss has been proven to be rubbish.

My favourite - How nuclear weapons were the best thing to happen to the world because the last few decades have been the most "peaceful" in human history, lol.
