Evidence that there are WMD in Iraq? Evidence that Iraq was an imminent threat? Oh, now you don't like evidence. I'm sick of OBL putting out videos, time to get a President who knows how to go after him.
A lot, actually. We do know that Hussein
had WMD's in the past because he
used them in the past. If a criminal used a gun in the past, and wasn't arrested, we know that he
had a gun, even if he does not have it currently. I fault neither Bush nor Kerry nor Edwards, all of whom publically thought Hussein had them at the time of the invasion.
We know that Hussein was a threat, as he had been consistently was firing on American (and UK, I believe) aircraft, and had plotted to assassinate a former US President (according to Bill Clinton). We also know that he had refused to comply with the agreements ending the Gulf War. How "immiment" that was depends on if those things are sufficient to constititute a reason for the invasion.
