Do you have a good suggestion for how to get the next superpower to agree to that kind of thing? I think the most likely outcome is that their allies will be allowed to do genocides where they want, and boycotts and blockades will only work on their enemies, probably.
I think will it will emerge as we get into multilateral world order. Given that those drones depends on global supply chains, satellite images, natural resources across the world, we could imagine that a in multilateral world, if the bigger players decide to pull the plug on the economic supply and/or supply drones themselves, the war is over for the smaller players. Therefore, we either have a global war or a mechanism of conflict resolution that we never seen before or we only saw in sci-fi movies and video games.
