I think at this point it's about how do you properly determine that someone is mentally severely unstable or mentally ill and if you get kicked out of the military for being mentally unfit to serve that's a Major warning sign, that coupled with the fact that the latest shooter had Asperger's syndrome too!
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
