Who lost the WMDs?

Instead of accusing the governing U.S. and U.K. executive administrations of misleading, exaggerating, or even lying to the public about Saddam’s weapons of mass destruction, I’d rather stipulate to their existence, especially the chem and bio weapons that western countries helped him develop. I have another question entirely: Where are they?
Have we indeed made it more likely that these weapons will fall into the hands of our stateless enemies? What an incredible security nightmare! Shouldn’t securing the WMD sites have taken precedence over securing the oil fields?
Apparently, the latest Bush administration line is that looters got the WMDs. Is that supposed to be comforting?
