I need to say, I think, that the young man who is my secular "Godson" has just passed out as a Marine in the UK. I assert that you can be absolutely certain that he and his comrades would have no truck whatsoever with atrocities like this. Nor, of course, are they asked to commit them.
This is not to open an argument about warfare, please. I wish that all our fellow human beings were willing to live at peace together. With our species, though, it ain't going to happen.
