LoL The truth is never OVER!!
From the 1874 Foreign Relations Committee from above.
"A child born within the United States, of parents who are not citizens, and who do not reside within the United States...shall NOT be regarded as citizens thereof."
The operative phrases from above are in bold.
Wow, they mean that the US government didn't believe that someone could be born within the United States could not be a US citizen?
Heck, then there is no way that person could ever be a natural born citizen LoL.
Was it passed in to law?
NO!
And all legal authorities would tell you that the 14th Amendment would vanquish any weird theory of Vattel’s anyway. (Even though NBC did not mean what you think it did, even before the 14th was ratified in 1868)
So, your quote from the past would not apply.
Also, I think the “anchor baby” issue we are dealing with can be addressed much like Senator Moran of Kansas suggests, by saying that the parents of anchor babies could not file for divorce and custody, in the United States, so that the children are not, “subject to the jurisdiction thereof”.
