I don't think there is one. An analogy is a special kind of abstract relationship. An antonym, or opposite, means something at the farthest possible extreme away--something at the opposite end of the continuum.
But something either is an analogy or is not (and that may even be a matter of interpretation or opinion). There is no meaning to the idea of being the farthest possible thing from an analogy. More.
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.
