We know where they [<nowiki/>Iraq's WMD] are. They're in the area around Tikrit and Baghdad and east, west, south, and north somewhat....I would also add, we saw from the air that there were dozens of trucks that went into that facility after the existence of it became public in the press and they moved things out. They dispersed them and took them away. So there may be nothing left. I don't know that. But it's way too soon to know. The exploitation is just starting.
