I think the defenders are of two kinds. There are plenty of people that were privileged by the regime, and they honestly want it to succeed. Consider the number of people in RUssia that are nostalgic for communism --- it was good for them.
And for others, as you said so well, it is either be killed by a crowd of Iraqis after torture or by a bullet from an American gun. All I care about is that they don't take any of our boys with them when they go down.
You too, Cardinal, have a good day.
