Of course taking out Saddam was the right thing to do, he did have weapons but moved them, just like Iran is now permitted to do with our blessing. Saddam was a murderer and now ISIS is using his gas.
The Christians, Jews and others being executed for being Christian, Jewish or some other non-approved theology disagree with you.
Taking out Saddam destabilized the entire region and unleashed Jihad in Middle East, North, Central Africa and on the West. This is W legacy. Saddam was in a box going nowhere. W put family business ahead of the nation business, that is an unforgivable transgression.
