which experts say includes language stating that it does not impinge on the U.S. Constitution's Second Amendment.

They put language in there STATING that forcing more unconstitutional regulations on us doesn't infringe on the 2nd Amendment. How freaking nice. I'm all warm and fuzzy, how about you? </sarc>

...the treaty calls for countries to adopt strict licensing requirements,...
... experts say includes language stating that it does not impinge on the U.S. Constitution's Second Amendment.

It would be intresting how this treaty reconconciles those two issues.

IIRC a treaty cannot superced the USC as delineated in Article VI:

This Constitution, and the Laws of the United States which shall be made in Pursuance thereof; and all Treaties made, or which shall be made, under the Authority of the United States, shall be the supreme Law of the Land;

To me that means 2/3 of Senators voting on a treaty cannot overturn any part of the USC. Article V - Mode of Amendment deals with that.

That said I too have not found case law on treaties vs USC; however, this court did issue the Heller decision.
