Let's assume for a moment that the presumption of the OP is correct, that Obama's bowing does indeed make the U.S. look inferior. What is the end result of that?
Is Japan going to attack again? Does it make our gigantic military less powerful? Do our nukes stop working? Is Japan going to call in its loans? Are other countries going to be less willing to meet with us or will it be harder for the U.S. to negotiate favorable terms? Are terrorists going to see it as a sign of weakness and launch a wave of attacks?
I want someone to describe to me in a tangible way how this matters in the slightest. Honestly, the only thing I see is that it will piss off some wingnuts, who don't like Obama anyway and wouldn't begin to start liking him if he acted differently in this situation. Seriously, Obama could have shoved a nuclear bomb up the emperor's ass and you guys wouldn't have changed your opinion of him.
This thread is just a joke. I need to stop reading in it. It must be like nicotine, you know it's bad for you, but you just keep coming back.
