Of course it is, now. Especially since the administration has changed from 'immediate threat' to WMDs to WMD 'programs'. First they were there ready to be fired and now they may not even have been in existence, just the material to possibly make them.
Considering the bag of lunatics that comprise your average middle eastern country, the material alone is reason enough to snuff the regime.
If nothing else, we've cleaned up some slop, knocked a few rogues back on their heels and made 'the street' think twice before messing with us.
Unless someone has some compelling reason why Saddam should still be in power (aside from, let's say, his internal reign of terror) I'm still hard-pressed to find the downside.
Let the handwringers wring their hands. I think we did the world a service, and ourselves too. How often does that happen?
Liar.
Find it. Anywhere. Any administration official using language close to "immediate threat". What part of "grave and gathering" do you fail to understand?
