BlueTrain,
Here are a few quick Wiki's that provide background commentary on this discussion of treaties, beginning with (an interim) draft of one of the Treaties being discussed (date 2006):
See especially "Cluster 4" and "Cluster 7" discusses 'disarmament' -
http://www.un.org/News/Press/docs/20...is3335.doc.htm
(cited as footnote #5 in the IANSA Wiki, 2008)
Note in the third sentence where it states: "The draft was approved by a vote of 139 in favour
to 1 against ( United States), with 24 abstentions (see Annex X)." (emphasis added)
The US representative to the UN at the time was this fellow -

And the organization working within the UN structure to promote such Treaties -

(see especially the footnotes.)
Anyone who thinks the entire Treaty issue is farfetched ought to read the history leading up to what occurred in Australia. Gun owners in Australia have gone on record noting that it did not occur overnight. Although no treaties were involved in that case, it may reasonably be inferred that IANSA is interested in pursuing similar outcomes more globally.
As to whether treaties such as the one above would be binding on US citizens or not, I suspect that there are very few precedents to examine.
FWIW.
