On the other hand, here we have an article, co-authored by Laurie Mylroie (who has intelligence connections, and who is very careful in her assertions), saying that Iraq "is strongly suspected of having" smallpox. It's seven years since Kamel defected, so there's been plenty of time for new acquisitions... The article, however, focuses mostly on anthrax.
From your second link:
The most dangerous agents in Iraq's arsenal are anthrax, which it is known to have, and smallpox, which it is strongly suspected of having.
