Obama following suit of other despots:
The Nazi salute, is a variant of the Roman salute, adopted by the Nazi Party to indicate loyalty and subservience to the party's leader Adolf Hitler. It was adopted following its use by supporters of Italian fascism, a political movement under the leadership of Benito Mussolini. The Hitler salute became the embodiment of Hitler's cult of personality throughout Nazi Germany.
