I think the USA has much more to be concerned about. Have you reviewed the candidates for the 2016 Presidential election? Now, THAT is concerning me because no matter what, the percentage of blacks and latino is the least of our problems.
You can be concerned with whatever you want.
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.
