re: But that wasn't what you said
If someone points a gun at a cop on a dark street, and gets his ass shot off by the cop, and it turns out to be a realistic toy gun, does this mean the cop shouldn't have shot the guy in the first place? Not a simple question, but given what the cop had to work with, few people would blame the cop.
Iraq gave us every impression possible that they not only had WMD, but were attempting to deliberately hide them.
Unless you can prove that the Bush Administration deliberately lied about this, I don't see it as an issue. Granted, it's not very reassuring to think our intelligence can be fooled, either, but that's a separate argument.
And we haven't finished looking yet.
