We are all born of this.
I would not have been born if not for the Cold War.
My parents would not have been born if not for World War II
My grandparents would not have been born if not for The War To End All Wars
There aren't any profound stories to tell, for me, about chance meetings related to these wars. It's just that those events were all so large that clearly if they had somehow been prevented so many things would have gone differently that even if somehow these two people had met and fallen in love, their children would have been of different sperm and egg, and context.
We clearly need a place from beyond regret, in order to begin to appreciate our lives at all, without shutting things out.
