Does this now validate the use of torture?

Saw an answer where it said don't be surprised if we see muslims water boarding our troops. This would be a step up for them since what we've seen is them decapitating American citizens with a dull knife. Look, these terrorists aren't subject to the Geneva Convention. They are the lowest filth and scum you can imagine. If torturing them will save American lives, I'm all for it. From what I understand, no enhanced interrogation techniques were used at Guantanamo, but I'd of been in favor of it if it had been.
