No, I am pointing out Iraq was under UN resolution to declare any weapons undestroyed, and a list of items was given. Assuming these types of weapons were on the list (and they almost certainly were) Iraq would have been in violation of sanctions, which means the terms of the ceasefire were breached and the ceasefire was null and void. Now we all know the UN was never going to act on this type of offense no matter what evidence could ever be found. This point was effectively made over and over in the months and years preceding Gulf War II.
So... the US unilaterally decided to take matters into its own hands, pointing out the obvious. Perhaps mistakenly the WMD argument was thrown in, and certainly imminent threat has not been proven, but... illegal weapons are being found, at least opening the possibility truly lethal WMD will be found.
FWIW, the reason the US can have the MOAB is the US isn't under UN sanction to not have it... in addition, it isn't the losing party in a war whose ceasefire is conditional on the US giving up such weapons.
There you go... I hope I put that in a way YOU could understand.
