I don't think there's any great mystery to writing female characters, so long as you talk to them. If you lived in a monastery and never met any women, maybe it would be difficult.

World War II is the greatest drama in human history, the biggest war ever and a true battle of good and evil. I imagine writers will continue to get stories from it, and readers will continue to love them, for many more years.
