They are all correct except for Kabuto, but the bubble guy has not been fully explained yet. Thus the purpose of the filler that is currently being shown. Hope this helps!
You have almost all of them and btw kabuto did not die and I know right whats up whit the new shipuden episodes yah same thing was on my name!
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.
