It has been said that a picture tells a thousand words.
The image is being broadcast around the globe by Iran of a female British soldier wearing a hijab is a powerful image and even more disturbingly it is an image of submission.
Not only is the female soldier a hostage, but she has chosen willingly to conform to Islamic dress standards. It is highly doubtful that she was under duress and forced to wear this. Most likely she was told to put it on and she complied willingly.
