During WWII, the Allies captured 5,000,000 Germans. Over 750,000 were sent back to America. Some of them were given jobs. Part of the US war effort was to make sure that the Germans knew how well they'd be treated if they surrendered. The obvious reason was that we wanted them to surrender.
Many of them, maybe even millions, didn't fire off every last round before they surrendered. They did not, when out of ammunition, fix bayonets and fight that way. They did not, in many instances, fight to the death to kill American troops.
This saves American lives. Donald Rumsfeld, John Yoo, John Bybee, David Addington, and others, obviously don't care about the troops. Rumsfeld kills troops dead.
How hard would you fight if you thought you would be tortured, perhaps killed, perhaps never to return home? How much of your last breath would be expended to make sure the people who wanted to do this to you died first?
American torturers kill Americans.
