You definitely have a book here in the style of Robert Rodat’s “Saving Private Ryan” or Alex Haley’s “Roots”. Even though the ending doesn’t quite satisfy because ultimately you are not related, it still resonates.
This is more of “Man’s inhumanity to man” story. The desire to control others has occurred throughout history. It’s many forms; War, Intimidation, Drugs, Genocide, Mass Media, etc. are nothing new. The illusion of peace is just that, an illusion. Even now, here in America, we are in flux with one group sure that their way is better/right/good. How are they enforcing their will? What are the tactics they use? My guess, is it will mirror one of the many tried and true ways.
Those who study history can mitigate some of it, but we are all touched by it.
