Treaties are potentially so threatening to the sovereignty of the individual States and the Union of These States that two thirds of the Senators are
required to be convinced that the treaty under consideration does not contravene the U.S. Constitution and/or adversely impact on the retained
functions and interests of the States before they consent/ratify.
In 1789, the States directly ratified the Constitution --- as per Article VII. Since then, the States through their representatives (their Senators)
must also ratify any treaty --- Article II, Section 2, paragraph 2 --- for the same reason, namely, that the creators (the States) must have the final
say.
There is a pecking order: God made People, People made States, States made the Union. Therefore, the Union is beholden to the States, the States are
beholden to the People, and all three are beholden to God.
Further, Article VI, paragraph 2 quoted above commands that if and when all of the above requirements for a treaty are met --- that is, a) it does not
contradict the Constitution; b) it is negotiated by the President who has sworn to not violate, and who in fact is not violating the Constitution; and
c) it is ratified by two thirds of the State-defending-Senators who have sworn to not violate, and who do not by their vote violate the Constitution
--- then, and only then, may the treaty in question go into full force and effect for the Union and for all of the individual States in the Union.
This latter consequence is the reason for Article VI, paragraph 2 to conclude:
"...and the Judges in every State shall be bound thereby, any Thing in the [not "this"] Constitution [ of any State] or Laws of any State to the
Contrary notwithstanding. [Emphasis added.]"
So, the Judges in each State must obey a bona fide treaty, even if the treaty is contrary to that state's Constitution or contrary to any law of that
state.
