Something that I think is really important to remember is that we never did torture POW's prior to Iraq 2. In fact, our good and fair treatment of POW's is often times spoken of having saved thousands of lives during WWII. The German soldiers all rushed to surrender to US forces, but fought to the death against the Russians, because they knew what would happen to them with both parties.
I guess my question would be, do you think that Russians were justified in torturing and killing german soldiers? How about Japan with US, Chinese and Korean soldiers? Was it OK for Vietnamese to torture US POW's?
While most people in the US don't care about the Geneva Convention, or rather don't really understand it, most people in the world do.
If you are going to be a moral authority on ANYTHING as a person, group or country, then you need to be above reproach.
The damage that torturing has done to our standing in the world is going to take alot to repair.
