Interesting debates on WW2?

I have to write a non fiction peice of writing and i have chose to do WW2. I need a good debate or view, for example.. ''were all the Nazis bad?'' (already deen taken) to write a 1000 word essay. The topic on WW2 cant be to big but narrowed down. Could be about Hitler.. Nazis, americans, anything about WW2 narrowed down as far as you like but It needs to have a good spin to make it internesting.
