In your opunion was every child of an American GI and a South Korean or South Vietnamese woman during those respective conflicts a U.S. NBC?

[DiogenesLamp]

In 1787, only a man could convey citizenship. The common law of the time made married women automatic citizens to whatever nation their husband belonged. This was for married people only. Children of illegitimate relationships derived their citizenship from their mother.

Perfect! That pretty much blows a hole in the idea if one parent is a US citizen then the child is a NBC. Clearly this could not be the case as the Constitutional NBC requirement would be utterly meaningless. Think how many US men have traveled to china and fathered a child who is then raised in China. How could that child possibly be a Natural Born Citizen? Of course they are not.
