Well if you think Sadam wasn't at the very least funding terrorist organizations you are delusional, then there was the group of choir boys called Ansar El Islam that had a base in Iraq, but none of that matters right? Iraq had all the ingredients to make WMD just not a delivery system ( So that makes it not a WMD for some reason).As far as the stuff that was already a WMD that UN supposedly was monitoring was in delapidated bunkers that was not being guarded or monitored.
When it comes right down to it there was more than enough reason to invade Iraq, them breaking the cease fire before the ink was dry in 91 is first on the list. So the war is "legal", as ill advised as it may have been.
