Barnett on Big Wars

I've been reading Tom Barnett's blog since seeing his talk at PopTech last year. He is a military geostrategist and his blog links to a large variety of excellent articles from the New York Times, Washington Post, Financial Times, Wall Street Journal, etc. with brief commentary and is currently one of my main ways of discovering interesting articles. Barnett is a big believer in the US military's need to transform itself to be better adapted towards small wars and 'sysadmin work' instead of the current (changing) focus on large wars with other global powers (e.g. Russia and China). I find the following comment to a McClatchy article on the need for big war capabilities the best explanation for why the US doesn't need to worry too much about the big war capabilities of ground forces:

Here is the missing piece to this argument: America can impose its big-war willpower nicely with air power and air power alone. If we're not going to own the aftermath, then we can just bomb, bomb, bomb and not care about what comes next. I can do that with air assets from Navy and Air Force. If I'm not going to put my ground forces at risk in small wars, why the hell would I put them at maximal risk in big ones?

If we are going to fight high-end, then it'll be missiles and drones and high-altitude bombers and guided this and that. It will not be the Marines storming some beach en masse, nor Normandy with the Army. In short, we can have our SysAdmin green force and use it too, while maintaining an appropriate lead in the blue Leviathan force.
