Tobacco cigarettes are more harmful by far as electronic cigarettes don't really have any toxins in them, exept for nicotine(in some cases not even that) And the last time I checked, inhaling a smell is much less harmful than 4,500+ chemicals.
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.
