@ossobuco,
I of course don't know about Petraeus. I've rather liked him, as much as I've known.
I'd have never made it in any army, though my father ended as a full colonel. I'd probably never have been any good at being a guerrilla either. Lack of fervor.
The loss of lives, stuff of literature, but why is this still going on when we can talk?
Munitions, that's why.
