Also he too has the typical American handicap; he does not really understand what culture is made off and all that it embodies, namely also moral and ethical values and mental institutions (famous Arab boring 'honour') as well as thinking patterns and interpretation of behaviour (courtesy, hostility, apologies, threats and when is what weak, strong, sincere or devious). This combined with the false notion that the world can be organized like a suburban ethnical mixed Chicago community (because it also must have a common communal interest to live together), without the use of force and without loss of US power, simply by talk, some threats, some wooing and eventually compromise. Saudi's were desert nomads, Arab peasants who had to learn RealPolitik real fast after OIL wealth and have realized Obama is an American provincial / peasant with a provincial worldview that is disguised with an image as a world wise cosmopolitan. His bow to the Saudi King was meant to strenghten that image but it is now clear it resembles the peasant in the big city imitating big city manners to hide what he is. These features are probably fine for domestic US politics, which after all is an enormous but in essence provincial nation, but it is recepy for disaster and humiliation when there is heat and cisis in the big city that is the world of RealPolitik. BTW; I was fooled too by his grande image and smooth talk, being a romanticus with love for grande words hinting there is a vision. But hell, me is fomcity and that is a city people handicap, thinking peasants can not act and talk, so that is as understandable a mistake as Obama's foreign bloopers.
