I felt "Iraqi Freedom" was justified even if the WMD case was flimsier than bubblewrap. Here's my reasoning.
o) I've been wanting to see Saddam go for a while. As has been mentioned, he is pretty damn brutal, and even though U.N. sanctions didn't help the quality of life in Iraq much, he amassed most of the nation's wealth for himself leaving his people in poverty. And then there's all the stories about Ba'athist brutality - killing people for the hell of it, the gassing of the Kurds...
I really felt that we should have taken him out back in Desert Storm.
This is a chance to try and bring the nation of Iraq out of a rule of suffering from the Ba`athists. Of course, the insurgents who want to either return Ba'athist rule, leave Iraq in a bloody civil war, or put Iraq in a religious state like Iran aren't helping ...
o) We pretty much know now that there are no WMDs in Iraq and apparently, they didn't have a WMD program. However, Saddam did intentionally put up a facade, pretending he had WMDs. Apparently one of his aides confided this to interrogators, saying that Saddam believed that if he could make the U.S. believe he had WMDs, they'd leave him alone (ironic, eh?).
So he was trying to make it look like he had WMDs, intentionally defying UN weapons inspectors instead of cooperating. As Bush pointed out, that's in violation of a U.N. resolution passed to keep Iraq in line. "You don't cooperate with our inspectors and we'll kick your ass over a teakettle."
Granted, Bush had the U.S. and its "coliation of the willing" act without U.N. blessings (especially since France, Germany, and Russia were determined to stop any action in Iraq), so the justification of this part is debatable.
I don't know what to say, really. Reconstruction of countries has worked before - need I mention Japan? (U.S. General MacArthur instated a benevolent military control of the country afer it surrendered) I don't think we have a MacArthur to deal with Iraq and its many people ... that and, as far as I know, there wasn't that many insurgencies or rebellions against the U.S. authorities in Japan.
For those that agree with the reasons I supported the war, but didn't support the war themselves, let's look at a different option; an assasination of Saddam Hussein without a full scale invasion.
If the CIA used an assasination attempt to remove Saddie Hussie, it would have left a power vaccum that would have been filled through blood - and most likely, Iraq would be left with someone as bad or worse than Saddam's Ba`athist government.
And if we left Iraq alone, the people would still be suffering with no hope of change. At least now, if the insurgencies don't win and the Iraq government succeeds, they have a brighter future.
Is war itself justified? That depends on the reason. If your people were facing genocide from an enemy, oh hell yeah, I'd say war is justified; you have nothing to lose, seeind as if you just let the enemy take you over, you'd die in a purging.
I don't feel that wars over resources aren't really justified, though. *waits for someone to say that Iraqi Freedom was really about the oil*
