Actually, I take it as, Trump is the first President to enforce the law correctly. The 14th amendment was written to codify that former slaves were residents of the US. This to put down the movement to send them back to Africa.
"Amendment XIV – Section 1. All persons born or naturalized in the United States and subject to the jurisdiction thereof, are citizens of the United States and of the State wherein they reside."
You should note that the former slaves, most of them born in the US were indeed subject to the jurisdiction of the US and no other country since it had been illegal to import slave for many years prior to them gaining freedom and the passing of this amendment.
I don't remember were it is exactly, perhaps Natural Law, that, No man is without a country. Thus the 14th amendment made it so.
Visitors to the country, legally or illegally, are subject to the jurisdiction of another nation, to this one only temporarily as a guest
and not at all as an illegal, that has already broken the law.
So the 14th amendment is finally interpreted correctly by Trump.
The same as we find that in the case of our own citizens born abroad. Like John McCain, a natural Born Citizen even though his place of birth was Panama. It is logical and consistent with how we enforce the law and with Natural Law as found in the
Law of Nations.
