>>And not finding WMD's does not change my opinion that Saddam was a threat.

If I'm standing down the street from your house, and I yell out, "I'm going to kill you", yet
I'm standing there empty handed, you cannot pull out a gun & shoot me because I threatened you.

There has to be an imminent danger to your well-being before you can act.

There was no imminent threat to the US from Iraq. Talk and threats don't equal action.
