"Now, an ally (Russia) of the coalition against the "Axis of Evil" is using (also against its own population) a WMD that the US is trying to prevent the Iraqis from using, by forcing the world to admit it's justified to attack them."

Unlike Saddam's deadly accurate use of WMD to intentionally kill 5,000 Iraqis, the Russians never intended to kill anyone with their gas, merely incapacitate the terrorists, and quickly rescue and revive the hostages. They unfortunately badly miscalculated the dosage, and the dire effects on the weakened systems of people who had barely eaten or drank liquids in 2 days. They wre also poorly prepared to quickly revive the hostages.

But to claim that the Russians used WMD is like claiming that a doctor is using WMD when he puts you under for an operation.
