Iraq on the basis of made-up "evidence" of non-existing weapons of mass destructions
You are probably unaware that chemical weapons are defined as WMDs in all the treaties related to WMDs.
And you are likely also unaware that Hussein used chemical weapons against his Kurdish population.
You are most likely also unaware that some chemical weapons were found when the US Army moved into Iraq.
Note that all those things were mentioned in the news at the time (at the time meant the Clinton Presidency in the first two cases, the Bush one for the third case), but presumably you don't (or can't) read the news either.
Which is why, presumably, you're still blathering about non-existant WMDs in Iraq.
