It is just a statement of fact that the geographic location a person is born is coincidence.
I disagree with nhchris’s response of
> It is their inheritance, their birthright, the fruit of their ancestors' labors.
Because there is no natural law that something is “your” inheritance, birthright, or that you have claim to the fruit of your ancestors’ labor. Might makes right is how nature works, and it just so happens that you were born in a time and place where certain “rights” are being upheld, and there is not a stronger party that wants and is able to take them from you.
You can even go further and replace place X and Y with parents X and Y.
and still: for the person born to "deserve" living with these benefits nebulously assumes the person, and the "deserving", were there first, and THEN you are born and by sheer chance, you got it - or not. Again, when you stop thinking this way, sort of "thinking of an abstract person" first, but rather realize that there are no abstract people, just real ones, this starts to feel weird.
The answer is: yes, people returned to many places after they were totally demolished, suffered from systematic resource drainage and were background of inhumane genocides. TLDR: massive scale war is nothing new.
Sadly
This is, in my view, one of the reasons america is so culturally weird. It’s generation after generation of the most antisocial families from other countries.
