We [in the U.S., anyway] mention "our large nuclear arsenal"
so we don't have to use it.

What you say is correct, though you don't point out the
contrast between {me'o pa}, the numeral "1" vs. {zo pa},
the word "pa"; likewise, between {me'o ny.}, the letter
"n" vs. {zo ny.}, the word "ny."

It is not different at the level of predicate logic.
By convention, its referent is taken to be a mathematical
object.  It is also syntactically different: "ko'a le mlatu" is two
sumti, even if the current referent of "ko'a" is a number,
whereas "ny. le mlatu" is a single sumti meaning "N of
the cats I have in mind".

No (forgot to say this before).  ".y'y.bu" is on the same
footing as "ny.", and combines with it to make a multi-letteral
variable/pronoun.
