JONATHAN, I just saw your post about TO END ALL WARS. Yes, some of the book is about protestors, but I am finding that to be a secondary theme of the book. It follows a few people through that era, some names you will recognize from previous books, but it is definitely about the war, how futile it was, how purposeless! As the author tells it, or as I remember the author telling it, (I'm reading this book now and then) Europe had been at peace for some years and it was as though they were itching to fight! Tired of the everyday routine, so to speak, they needed an enemy.
But I think you would enjoy reading it!
