Gen. Petraeus wears Islamic turban in Afghanistan
After seeing this, I no longer have any respect for Petraeus, who shouldn't even be wearing what looks like a primitive coat. He doesn't need to wear a military uniform; he could wear a suit and tie, but to wear what may be tribal gear is just as insulting as that headpiece.
Update: and while we're on the subject, Rob Miller's discovered more about just how bad Petraeus and his aides are. This man is not suited to lead the US army, and should resign.
