Everyone had bad information regarding WMD, not just the US. Afterall he used chemical/biological weapons against the Kurds. That's a fact (an indisputable fact as Jay Carney likes to say). Saddam Hussein continued to give appearances of having WMD all throughout the 1990s. Apparently it was the card he was playing against Iran.
All that being said we found it to be not so, but only after going into Iraq to finish off what was left undone in 1991.
So every Monday morning quarterback with 20/20 hinesight claims that the Bush administration lied... knowingly lied.
That's quite cynical.
In the meantime Obama gets every pass and excuse possible.
That's not only cynical, but ideologically blind.
