So, did bowing to the Emperor of Japan mean he’s now converted from Islam to Shintoism?
In both cases think it just means he’s an idiot...
No. After the incident with the the King the reaction was politically bad so he bowed to other foreign heads of state to indicate that, well, that was just a personal eccentricity. He doesn’t do anything without a particular reason except sometimes get fumble tongued when separated from his teleprompter.
