Minor vs Happersett 1875
Chief Justice Waite:
“it was never doubted that all children born in a country of parents who were its citizens became themselves, upon their birth, citizens also. These were natives, or natural-born citizens, as distinguished from aliens or foreigners.”
Okay, well, you may be right.
I still don’t like it that children of military officers serving abroad should not be regarded as native born citizens, though.
