Not to mention if he went through actual torture you would think the methods we use would seem like a cakewalk.
That's what I was thinking, myself.
Decent and civilized people are squeamish about using torture, and so rare and gentle in its application.
The North Vietnamese on the other hand never had any such qualms.
I suspect the "worst" "torture" that anyone has been subjected to under our system, is much kinder, much gentler, than the "easiest" torture endured by those under the control of socialists and terrorists.
Given what he went through, I'm sure to John McCain, "waterboarding" is a cakewalk, an absolute cakewalk.
