That's why I say "between superpowers". In rough terrain when a full air campaign is not being waged, the population hates you, principles from "Total Resistance" are being applied, and there are places to hide, air power is not a panacea. In division-level wars between superpowers, it is the only thing that matters (except nukes) though. Remember Iraq and Afghanistan were still occupied by us so they lost their respective initial wars. Only after extended guerilla warfare and attrition were they able to triumph.
