Really you should be looking at what interests you. What hobbies do you have or like? What sports do you play or like?
History? Politics? Science?
Social issues? Environmental issues? Point is... if you find it interesting then you will have a much better report.
Randomly picking a topic is almost always a bad idea because you won't give it 100%.
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.
