ya, and khalid sheikh mohammad lasted for 2.5 minutes doing that... do you think he would have talked using another way??? nope
people can piss and moan all the want about whether it is torture or not, I could care less... they did what they needed to do to get quality intel out of mohammad, it WORKED, it SAVED LIVES...
edit - and fwiw, i don't consider the water board to be remotely in the same league of torture as methods like "death by a thousand cuts", bone breaking, having your finger nails ripped out, electric shock, tooth extraction, branding, forced circumcision and many others...
