Not all those found guilty in WWII where punished ie: Japanese commander in China/Korea, that used biological warfare on civilians and captured soldiers. He later became the head of a huge multinational medical company. Several Germans where brought to the US to assist with the space program, their past buried and gone. Yes, the US, Britain and more so Russians tortured. The Russians talked about it several years ago, they took captured germans, tortured them, once they talked they would be taken away to be shot or hung. The level of torture the US is alleged to have done in Iraq, is tame in comparison.
