I don't think Petraeus really has any business telling American civilians how they may politically express themselves, whether it's burning a book (which BTW is a dumbass thing to do), drawing a political cartoon or producing a television show -- all of which can result in protests in Islamic countries. US troops are in danger simply because of who they are. There doesn't need to be an "incident" to set off a terrorist.
