Torture is def not the way to go. Been proven that info you get from torture often is not true. MAIN REASON: if our troops our captured by a government (not terrorsist) you hope that in return that government DOES NOT torture our troops. It will also encourage the enemy to surrender a losing fight thus saving lives on both sides if they know they won't be tortured. On the other hand they will fight to last breath even if facing a sure death if they think they will be treated with harm. Thus resulting in more casulties for both sides.
AND is against the Geneva Convention which we should stand by. Here is link for it if you wish to read up on it:
