Bob, I'm sorry to hear about your loss. I'm sure for everyone who loved her, Liz's death will spur up the discussion about the necessity of it all.
Interestingly, yesterday evening I saw part of the movie
Starship Troopers, and was amazed by the similarity of the moral and philosophical issues suffrage, civic virtue and the necessities of war today's youth is dealing with. Have you as a teacher, discussed this book/movie with your students?
Regards,
Hanno
