I'm no expert, but the Russians, French, and Germans had a great deal supplying arms to Hussien under the "oil for food program"
Once they realized that the US was going to invade and knock down the Hussein regime, they had to cover their asses.
Get rid of the evidence before the Americans arrive.
Just my take on it.
Thanks, Jet Jag! Sounds logical. I just wish the media would explain crap like this when they tell us about it!
