Show me a photo of any American president besides Obama that bows to the waist to any king.<quoted text>You are full of crap. There are a hundred pictures of every President making a bow to the leaders of different nations that bowing is the custom. No different than a hand shake in the US. And bullshit on one bowing makes the other a non-equal. The Kings bow to each other so what's that make them? You are so stupid in most of the post you make. Just post everyday you HATE Obama and let it go at that.
There are bows of politeness, and bows of subservience. Obama gave an unmistakable bow of subservience, head below the waist.
You will not see any other monarch bow in such a way to any monarch they are not surrendering to. They greet each other as equals, which means they do not offer their head to the other monarch, which is the symbolic gesture of the bow of the head below the waist.
You are very ignorant of protocols.
