This doesn’t have any clout in the US unless and until the Senate agrees.

Yes, it does -- see my last.
Example: Congress, if this thing is signed, "could not" pass a federal open-carry law. Or any law that countenances private ownership of firearms.
This traity -- errr, "treaty" -- would "set a new tone" delegitimizing the Second Amendment and our RKBA.
That's the whole idea.
