We shall not be afraid.
A blueprint (1984):
"War, it will be seen, not only accomplishes the necessary destruction, but accomplishes it in a psychologically acceptable way. In principle it would be quite simple to waste the surplus labour of the world by building temples and pyramids, by digging holes and filling them up again, or even by producing vast quantities of goods and then setting fire to them. But this would provide only the economic and not the #emotional basis for a hierarchical society."
