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 s 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.
