No, the children of diplomats are NOT “—subject to the jurisdiction thereof-—” and would not be citizens at birth, automatically.
The vast majority of conservatives disagree with bithers, on citizenship issues.
However, I have never heard a single of your opponents argue that a child of a diplomat would be a citizen. You are errected straw-man arguments.
Another point: the foreigner, Vattel, was never a citizen of this country, was never a voter in this country, was never a delegate to the Continental Congress, or the Constitutional Convention. The Foreigner, Vattel, was not a signer of the Declaration of Independence, and he never served in Congress.
Vattle is not a binding legal authority.
Vattle is mearly a legal reference and foot note in history, nothing more.
When Congress had no other guidlines, Courts looked to Common Law and Natural Law for instruction.
However, Congress has noe deifned Citizenship, and Acts of Congress trump Common Law and Vattel.
you just id why common law during the writing of the constitution would not have flowed citizenship by place of birth and instead by fathers loyalty.
