Oh, but it’s not a ‘Stockpile’ of UN Proscribed weapons, see?
In a radio interview Secretary Rumsfield states the following:

Now what’s actually happened? Right now you have the Iraqi Survey Group, which is a multinational group that’s out there reviewing documentation and looking at suspect WMD sites. I was with the Polish minister of defense this weekend in Istanbul, Turkey at the NATO Summit. And in the course of that, he pointed out that his troops in Iraq had recently come across – I’ve forgotten the number, but something like 16 or 17 – warheads that contained sarin and mustard gas.

I’m certain there is some valid reason why we are still debating the ‘why’ of us going to war in Iraq, I just have no idea what it is any longer.
