I think people have had the understanding for many years that whatever happens with the separation of parents, that the kids automatically go to the mother. The fathers don't know their rights.
I wrote about World War II because I didn't understand it. I think that's the reason that historians are drawn to any subject - there's something about it that doesn't make sense. I wanted to work my way through what happened slowly, and look at everything in the order in which it took place.
