Would it kill President Ahmadinejad to put on a tie occasionally?

I can understand co-opting Western fashions to make oneself seem more part of the modern world and all, but doesn't anybody have the nerve to tell this guy that he's dressing completely inappropriately for a man of his station? Or is there some cultural taboo that I'm not aware of, that keeps Mahmoud Ahmadinejad from wearing a necktie?
