Oh you mean the caches of weapons sold to Iraq by the US that had been buried for decades?

As opposed to the rationale for the invasion which was Iraq building stockpiles of WMD from their own factories?

Or are you talking about a different cache of chemical weapons?

Or about how the CIA consistently funneled bad intelligence to the state dept. who knew it was bad and still lied about it?
