I can read the Constitution, and I don’t see “Vattel” in it, nor do I see a cross-reference to it. Where does your loyalty lie, to the Constitution, or to Vattel? Answer the question, yes or no.
Vattel was the legal foundation for the constitution where it was needed. Therefore, your question is stupid. It is not I who attempts to disparage the constitution as written, neither do I seek to weaken its boundaries and restrictions on human greed.
