Apparently, Bush supporters are getting pretty desperate.
Given that the provenance of this particular artillery shell is completely unknown, it's a little early to claim it as justification for the invasion.
1. Its country of origin is unknown.
2. Quite how it fell into the hands of Iraqi insurgents is also unknown. Obviously, as David Kay pointed out, had they known what it was they wouldn't have used it for the purpose they did... it was completely ineffective for their purpose. Somebody's cousin could have found it while plowing their fields in the former warzone, or it could have been inadvertently mixed in with the usual HE stuff as the war with Iran ended... not a tough thing to accomplish with conscript labor... very difficult to say.
So far, about all that can be determined is that it's a stray, whose possession by anybody other than the former govt of Iraq was brought on by the chaos of Invasion by the US...
Let us know, however, when and if sufficient stocks are located to justify the claims of Iraqi deception and non-compliance. Nobody's going to be holding their breath... The one thing that none of the Bush-fans even consider in this whole scenario is the rat factor- sucking up to the conquerors is as old as war itself. Anybody who could lead US forces to caches of CBW agents would be very well rewarded, very well indeed. And yet nobody has come forward. There's really only one very obvious reason, and that's because those stockpiles don't exist.
Israel is a Democracy? Funny, somebody needs to tell the native Israelis of Christian and Muslim descent that- they only get 3/5 of a vote, and those in the territories occupied since 1967 get no vote at all. Israel is an ethnic theocracy with democratic features, at best... about as democratic as the pre- civil rights South in the US...
