ZOMG war is ugly WTF LOL
Waterboarding only causes emotional damage.
Sigh. This is factually incorrect.
Waterboarding can cause lung damage, dry drowning, brain damage due to asphyxiation or death. This is in addition to severe psychological damage, obviously.
Secondary damage of severe bruising and broken bones nearly always occurs due to involuntary struggling or spasms unless proper medical restraints are used to immobilize the subject.
The entire point of waterboarding is to trigger the body's natural reaction to drowning. Basically, to make the body think it is in the process of dying. That process makes the brain do specific things. If you were to waterboard an infant or person without higher level brain functions, their body would react the same as if you or a terrorist were being waterboard. Involuntary spasming, gag reflex, pain responses, etc. Ergo, it is not merely psychological torture.
As for the law. Torture is specifically defined under Title 18, Part I, Chapter 113C, § 2340. (

I'm not sure how folks got into the mindset that one can debate if torture is acceptable or not. It's illegal to do so in America (or its possessions) or to be done by Americans. Conspiring to do so is also illegal. That's like debating whether or not grand theft auto is acceptable or not. It is currently a crime. It is specifically illegal and specifically defined. One can, of course, debate whether torture should be legalized.
Obviously any specific case of activity that may be construed as torture is up to a federal court to decide if it meets the criteria. But, yes, waterboard is torture and therefore is illegal under Title 18, Part I, Chapter 113C, § 2340 unless otherwise allowed by law (not EO). This is not 'opinion', this is following the legal definition as specified by Title 18, Part I, Chapter 113C, § 2340
The correct question should be 'should torture be made legal' or 'should exemptions be passed into law amending § 2340 and the War Crimes Act to allow torture under specific circumstances'. Proclaiming torture (of any kind fitting the criteria specified in §2340) is legal is proveably false. Proclaiming waterboarding does not fit the criteria specified in §2340 is also proveably false, but each instance would obviously have to be judged on its specific circumstances in a federal court. The whole 'innocent until proven guilty' thing applies to torturers.
