Trouble is, most of the hated is transferred toward America and the American military. The terrorists are living among the "good" Iraqis.
Those who dream of Saddam's Return, no doubt are helping the terrorists. The remainder are the ones that count. But even many of those who support the terrorists will see it is pointless, and give up on them. The tide is already turning against the terrorists.
Executing Saddam is an important step for the Iraqis to control their country. They should execute him, then have a trial. The sooner they execute him the better for everyone.
