I appreciate your comment and perhaps need to look into this further, but the book those quotes come from also gave examples from other cultures around the world who have experienced the same kind of coming together during times of crisis. As I already noted, "Thirty years later, H. A. Lyons would document an almost identical phenomenon in riot-torn Belfast."

I'm sure it wasn't all fine and dandy during the Blitz, but from what I've read, London and Dresden, which both took heavy bombing, had better morale than other cities which took less. That doesn't mean that PTSD and such didn't exist, just that it was much less than would have been expected under such circumstances.
