The New York Times story "America will be the chef and its Nato allies the bus boys who stay to clean up the mess" pictures a possible future US/Nato relationship that is asymmetric in just about every possible way.
But that the asymmetric relationship is already here, and a better description of it is "The Good Cop / Bad Cop Act". You know: "Look kid, I wanna believe you. I care about your hyoomon rights. But the US over there, he just wants to hurt you!" "UNG!" "See, he's angry. He's getting his night-vision goggles on and everything." "I'm ah fuck you up!"
The trick with that, as with all acts, is to not forget it's an act.
