A serious rift between Obama and the Saudis would be a good thing for America, but I don't think anything will become of this one, if it exists.

The Saudi king is the keeper of Mecca. In Islam he's up there with Mohammed. So the most likely scenario here is that he's angry with Obama and punished him by sending him to stand in the corner like an errant child. It's certain that Obama would never purposely offend the king and Holy Sacred Muckymuck.

My bet is that Obama didn't follow the kings instructions, and it's hard to say which those might have been. Maybe our Great Leader hasn't clamped down on our oil production enough, or his refusal to attack Iran, perhaps.
