Disclosure: I've only seen one episode of Avatar (the cartoon) and have only heard about the plot of the movie Avatar. From what I seen and heard, the two are not related.
I don't think they are related to know the difference download the show's episodes as well as the movie from the link below.
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.
