I do for many reasons:

1) Saddam was the current generation of Hitlers, We have found hundreds now have mass graves with hundreds of bodies, nd they where even blindfolded, Which shows they where mass killed, and the eyewitness's who have told stories of how his brother would put people in cages with his live Lions and watch the get eaten to death, And countless rapes of woman and young girls. The people of Iraq had to live a life non of us in a country as blessed as ours can even picture in our head, and this is why so many people want to say there is no way the stories can be true, Well just because we dont have it happen here doesnt mean it doesnt happen. He killed thousands of innoscent people ( His own people ) and jailed thousands more on false charges.

2)He has used chemical weapons against other countrys and even his own people, So just because we havent found any yet or even if we dont, he has had them so they are out there somewhere.

3)Terrorism: The country was yet another location for Al Quida to hide and train thier people, Saddam was involved in so many levels in this, against his own people and other countrys.

In order to help stabalize the middle east we had to do this, The bad part is the new battle ground for terrorism has shifted to Iraq, and itmay keep the US from getting hit here, But now Alquida till we can stabalize the country thats where the war on terrorism will be fought, But better there then here I say.
