Maple,
While the weapons may have been found, there's been no confirmed evidence (offered to us mere mortals) that they actually contained anything. When found, it was suspected that they may have done, and then it went quiet.
And while Saddam's posession of Al Samoud and Al Fatah missiles (even though these were not operationally deployed) was a breach of UNSC resolutions, and was thus a good excuse to go in, but that was not the reason that our politicians gave for our intervention. The democratic legitimacy of the war as we fought it was founded on the supposed fact that Iraq presented a clear and present danger to us, with WMD that were deployed and ready for use.
Moreover, with the CIA circumventing international law and the norms of civilised behaviour by kidnapping and torturing suspects, the USA is leaving itself open to some of its servicemen deciding that this was not what they joined up to serve and protect.
