"The essential act of war is destruction, not necessarily human lives, but the products of human labor. War is a way of shattering to pieces, or pouring into the stratosphere, or sinking to the depths of the sea, materials that might otherwise be used to make masses too comfortable, and hence, in the long run, too intelligent."
That was written over 60 years ago; and likely has been thought about over and over again through every decline of every major empire through out history. These are not new ideas.
