Meanwhile, Allahpundit over at HotAir thinks that this may not be Obama's fault - his incompetent staff could be to blame:
...I’m not convinced that the “groveling” explanation for the bow is necessarily the correct one. For one thing, his protocol office is famously run by imbeciles. They may very well have simply given him bum advice: “Be sure to hunch way the hell over and stare at the ground. They all do it that way.” For another thing, and somewhat notably, Japan isn’t a stop on The One’s world apology tour. It could have been, but he declined the opportunity to turn it into one. So why give the emperor the full Hopenchange treatment, then? Is it just … reflex at this point?
