the only counter-argument I have heard to this is:
do you want the enemy doing the same thing to our troops when captured?
personally, I think they already do much worse to our troops, so to me it's a moot point.
You gotta be kidding yourself if you think that these terrorsits treat our tropps well when they are captured. Beatings, drills,disfiguring, beheadings and other mideval methods of torture are employed by these 3rd world contries and terrorists who were never present at the Geneva Accords. Waterboarding is the least of what they are doing. If we need to live up to what was signed in Geneva fine. Turn these thugs over to a country that never signed or have a liason interrogator from say Pakistan but the boot to them. You won't hear anyone whining inhumane blah blah blah then.
