This guy is talking out his backside!
Even the UN disagrees with him!

1. Adoption
"Adoption" is the formal act by which the form and content of a proposed treaty text are established. As a general rule, the adoption of the text of a treaty takes place through the expression of the consent of the states participating in the treaty-making process. Treaties that are negotiated within an international organization will usually be adopted by a resolution of a representative organ of the organization whose membership more or less corresponds to the potential participation in the treaty in question. A treaty can also be adopted by an international conference which has specifically been convened for setting up the treaty, by a vote of two thirds of the states present and voting, unless, by the same majority, they have decided to apply a different rule.
[Art.9, Vienna Convention of the Law of Treaties 1969] 2. Acceptance and Approval
The instruments of "acceptance" or "approval" of a treaty have the same legal effect as ratification and consequently express the consent of a state to be bound by a treaty. In the practice of certain states acceptance and approval have been used instead of ratification when, at a national level, constitutional law does not require the treaty to be ratified by the head of state.
[Arts.2 (1) (b) and 14 (2), Vienna Convention on the Law of Treaties 1969]
Having noted that it should also be noted that the US was not a signatory of the Vienna Convention.
Vienna Convention on the Law of Treaties
Is the United States a party to the Vienna Convention on the Law of Treaties?
No. The United States signed the treaty on April 24, 1970. The U.S. Senate has not given its advice and consent to the treaty. The United States considers many of the provisions of the Vienna Convention on the Law of Treaties to constitute customary international law on the law of treaties.
Good on Morris for calling attention to it, but he should at least know what he's talking about.
You got a video link?
