If there's no evidence for a thing, then there is no reason to believe that it exists. Once evidence is found and tested, then it is reasonable to accept that. Some thing exist without being known, but the difference is that all things are knowable, one has to check for the evidence.
And, if the evidence says that a thing does not exist, then that's the answer. 'Extraordinary claims require extraordinary evidence.' Carl Sagan.
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.
