People like this might be around in 100 to 200 years, but they will be a rarity. The general trend today is: Some white women with British and German(ic) ancestry have children with black and Latino males. Some white men of British and German(ic) ancestry have children with Asian and Latina females.
It could be that a half-Asian and half-white child from one of these unions has children with a half-black and half-white child from another, but that's unlikely due to numbers. It's more likely that these mixed kids will have children with fully white partners or with Latin/Hispanic partners, thereby being absorbed into one or the other "race". The future population of the US will probably be mostly Latino Hispanic, which means mostly Native American with some European and African and Asian ancestry.
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.
