Actually...
...it wasn't a lie. A lie is when you know something is untrue. Also, the Democrats (including Kerry) are quoted as saying that Iraq poses a threat and that they possess WMDs. And it's not too unbelievable to think Iraq was trying to get a nuke (which you emphasized). Israel had to destroy a reactor in Iraq because they were going to weaponize nuclear material.
And you all seem to be unaware that Saddam tried to assassinate George HW Bush and ALSO harbored terrorists who killed Americans (this is a verifiable fact, and makes him accessory to murder, which makes him as guilty as the terrorist). He also put a $20,000 bounty per American, an offer made to all Arabs.
And don't do the whole "blood for oil" thing. Doesn't work. If we were there for oil we woulda stopped on the first day (when we captured the oil fields) and gas would be .20 a gallon.
