The gold standard for executive authority in this world is clear. If you're the top guy, you get guarded by the U.S. Secret Service. This is the only explanation I can find for this picture. Here's the leader of Hezbollah, fanatical turbanist group. He's in full Iranian-style mullah/politician getup, but his guards look like Jean Reno Eurotrash versions of Dubbya's heavies, all the way down to the dark glasses and the expensive suits.
The effect for me is more Bad Hip-Hop Video than Imposing World Leader, but I bet it plays well back home.
