War is about achieving political objectives by doing evil things to enemy civilians until enemy fighters decide their competing political objective isn’t worth it. I used to think it was about things like logistics and infrastructure, but now I see those are just the means to the end which is to inflict horrors on the innocent family members of combatants until the combatants themselves become morally exhausted. For this reason, it doesn’t make sense to commit war crimes in secret–opposing forces must learn of them so they can be properly horrified by them. The innovation of 4GW is to balance the public image of having the moral high ground with doing the most evil things you can get away with. If media becomes fully polarized, say in a world war, then the usefulness of propagandizing neutral parties decreases and the winner is determined by who wants to win enough to do the most horrifying things the most effectively. I submit this as the fundamental basis for the Sukhomlinov Effect and the common observation that “the only crime in war is losing”.
Anyone who says they look forward to this sort of thing is out of their mind for one reason or another.
