The rounds were found from former swamp bed (Saddam dried these swamps
in
effort to catch the Shiia rebels after 1991) and were estimated to be
10+
years old by US specialists.

Uhmm...the last I heard the dating was inconclusive as of yet, with
various
sources making differing claims, from "ten years" (which would of course
have been *after* ODS--it could be over *thirteen* years old and still
have
been a post-ODS cache), to "the Iran-Iraq War". In the end, it does not
really matter--Saddam turned in repeated and differing accounts detailing
his alleged destruction of WMD...do you think he listed any of it as "Gee,
we lost it and don't know *where* it is"? I doubt it. Face it, he did not
meet the requirements.

I believe he claimed to have destroyed or disposed of those weapons, but not
so surprisingly no one believed him.
