You can run, but you can't hide.
Here is the main UNSC resolution sanctioning Iraq:

Now, show us in this or any other UNSC resolution where IRAQ is banned from acquiring, developing, or using "any bomb, grenade, rocket having a propellant charge of more than four ounces, missile having an explosive or incendiary charge of more than one-quarter ounce, mine, or [similar device]".
Unless you can show us where the UNSC has banned these devices from Iraq, then your use of the phrase "banning WMDs from Iraq" clearly must be referring to nuclear, biological, and chemical weapons. And by your very own use of "WMD" to refer to chemical, biological, and nuclear weapons, you are admitting that using "WMDs" to mean anything else is arrant nonsense.
Edit: Checkmate.
