Vattel IS in the constitution, Can’t you read?
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.
My guess is that Oceander can read a whole lot better than you.
So, you insist that Vattel is IN the Constitution. Great.
Article, Section and Clause, please.
