Actually, I don't think the NY Times as changed their mind. Note that this article is about UN monitored WMD. The UN was aware of several stockpiles before the war and inspected them before they were kicked out. I think those stockpiles are what the article refers to.
Actually it's not even UN monitored WMD. It's UN monitored stuff that could be concievably be used to make WMDs, not actual WMDs.
Don't know if I have the patience to explain why Newsmax is hopelessly lost and clueless on this story.
