Are you just testing the old maxim, "Repeat a lie often enough and people will start to believe it"?
How do "we know that Saddam had WMD"? From the self-serving lies of Iraqi traitors who fled Saddam's regime? We don't "know" diddly. The only thing that is clear is that the Iraqi scientists have consistently said that the weapons program was dismantled after the first gulf war, and that no WMD are in evidence on the ground with over a hundred thousand troops on the ground there.
"We know"...sheez, what a pack of lies.
We know because he used them and they were never destroyed by the inspectors after that act.
We know because we have proof he purchased things from France and Germany that were forbidden under the sanctions.
We can be fairly certain because the intelligence agencies of EVERY OTHER COUNTRY said that Saddam had them - it wasn't just our intelligence.
So please, tell me again how it's a 'lie' that we know Saddam had WMD.
