Topics for suggestion would be the fight against aids, doing more to help the hungry and /or homeless, breast cancer, pollution, going "green, violence against women, child abuse. If you pick a topic that is close to your heart it will be easier to answer and you will sound more genuine. Good Luck!
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.
