Actually I'd dispute that; modern warfare between major powers can only waged by proxy wars between lesser powers who do not have recourse to nuclear options. In the future as the destructive potential of smaller and smaller actors increases over time, humanity will have to get used to the idea that it can't go around just acting like a pack of spoiled murdering bastards with an entitlement complex, or it will end up destroying itself as the power threshold of the disenfranchised actors approaches mutually assured destruction scenarios. So perhaps in light of this it might be a good idea being practical to get used to that fact and stop acting like endless bullying war is a realistic long term foreign policy?
