My opinion on Iraq is that it was the right war, but the wrong method we choose to go about fighting it.
What Bush should have done...
(If all events up until our liberation of Iraq were the same)
2003 March - Invade and oust Saddam.
2003 Dec. 15, 2003 - Capture and Execution of Saddam
2004 Jan 1 - Declare victory and leave.
Repeat as necessary. They will get the message.
I almost forgot.
March 2003 - Congress declares war.
